The parameters are functions that can be connected to a digital input terminal. The text DigIn Slot A.2 means the second input on the slot A. It is also possible to connect the functions to time channels. The time channels work as terminals.

It is possible to monitor the statuses of the digital inputs and the digital outputs in the Multimonitoring view.

It is possible to monitor the mechanical brake with the monitoring value Application Status Word 1 in the monitoring group Extras and advanced.

The Mechanical brake control function controls an external mechanical brake with a digital output signal. The mechanical brake is opened/closed when the drive output frequency breaks the opening/closing limits.

The motor stall protection function gives protection to the motor against short overloads. An overload can be caused, for example, by a stalled shaft. It is possible to set the reaction time of the stall protection shorter than that of the motor thermal protection.

The stall status of the motor is specified with parameters P3.9.3.2 Stall Current and P3.9.3.4 Stall Frequency Limit. If the current is higher than the limit, and the output frequency is lower than the limit, the motor is in a stall status.

The stall protection is a type of overcurrent protection.

A maintenance counter tells that maintenance must be done. For example, it is necessary to replace a belt or to replace the oil in a gearbox. There are 2 different modes for the maintenance counters, hours, or revolutions*1000. The value of the counters increases only during the RUN status of the drive.

When the value of a counter is more than its limit, an alarm, or a fault shows. It is possible connect the alarm and fault signals to a digital output or a relay output.

When the maintenance is completed, reset the counter with a digital input or parameter P3.16.4 Counter 1 Reset.

Each of the three detection levels (Warning S1, Warning S2, Alarm/Fault) has a configurable timer associated that delays the response. The timing principle is like an electrical fuse where the response time is long for low levels and it is short for high levels.

The Multi-pump function allows controlling a maximum of 6 motors, pumps, or fans with the PID controller.

The AC drive is connected to a motor, which is the regulating motor. The regulating motor connects and disconnects the other motors to/from the mains with relays. It is done to keep the right setpoint. The Autochange function controls the sequence in which the motors start to make sure that they wear equally. It is possible to include the regulating motor in the autochange and interlock logic, or set it to be always Motor 1. It is possible to remove motors momentarily with the Interlock function, for example for maintenance.

If the PID controller cannot keep the feedback in the set bandwidth, a motor, or motors are connected or disconnected.

When to connect and/or add motors:

• The feedback value is not in the bandwidth area.

• The regulating motor operates at a close to maximum frequency (-2 Hz).

• The 2 previous conditions are true for longer than the bandwidth delay.

• There are more motors available.

When to disconnect and/or remove motors:

• The feedback value is not in the bandwidth area.

• The regulating motor operates at a close to minimum frequency (+2 Hz).

• The 2 previous conditions are true for longer than the bandwidth delay.

• There are more motors that operate than the regulating one.

The programming of inputs of the AC drive is flexible. It is possible to use freely the available inputs of the standard and optional I/O for different functions.

It is possible to expand the available capacity of I/O with option boards. It is possible to install the option boards in the slots C, D, and E. For more data on the installation of option boards, see the Installation Guide.

Use the Auto-cleaning function to remove dirt or other material from the pump impeller. It is also possible to use the function to clear a blocked pipe or valve. It is possible to use the auto-cleaning, for example, in wastewater systems to keep the performance of the pump satisfactory.

Use the Frost protection function to protect the pump from frost damages. If the pump is in sleep mode and the temperature that is measured in the pump goes below the set protection temperature, operate the pump at a constant frequency (that is set in P3.13.10.6 Frost Protection Frequency). To use the function, install a temperature transducer or a temperature sensor on the pump covering or on the pipe line near the pump.

It is possible to program the source of the frequency reference in all the control places, except the PC tool. When using PC, it always takes the frequency reference from the PC tool.

When pressurizing a long pipe that has many outlets, the best position for the sensor is in the middle of the pipe (the position 2 in the figure). It is also possible to put the sensor directly after the pump. This gives the right pressure directly after the pump, but farther in the pipe, the pressure drops with the flow.

The motor thermal protection prevents the motor from becoming too hot.

The AC drive can supply a current that is higher than the nominal current. The high current can be necessary to the load, and it must be used. In these conditions, there is a risk of a thermal overload. Low frequencies have a higher risk. At low frequencies, the cooling effect and the capacity of the motor decrease. If the motor has an external fan, the load reduction at low frequencies is small.

The motor thermal protection is based on calculations. The protection function uses the output current of the drive to know what is the load on the motor. If the control board is not energized, the calculations are reset.

To adjust the thermal protection of the motor, use the parameters from P3.9.2.1 to P3.9.2.5. It is possible to monitor the thermal status of the motor on the display of the control panel.

With a PM motor, use the I/f Start function to start the motor with constant current control. A high power motor gives the best effect. With a high power motor, the resistance is low and it is not easy to change the U/f curve.

The I/f Start function can also give a sufficient torque for the motor at start up.

A priming pump is a smaller pump that primes the inlet of the main pump to prevent suction of air.

The priming pump function controls a priming pump with a digital output signal. It is possible to set a delay to start the priming pump before the main pump starts. The priming pump operates continuously while the main pump operates. If the main pump goes into sleep mode, the priming pump also stops for that time. When waking up from sleep mode, the main pump, and the priming pump start simultaneously.

Use the advanced sensorless control function in applications where good speed accuracy or high performance at low speed is necessary, but encoder speed feedback is not used. With the advanced sensorless control, a simple closed loop motor control can be replaced with a high-performance open loop motor control. An example of a possible application is an extruder.

The advanced sensorless control function is not supported when a sine filter, a harmonic filter, or a synchronous reluctance motor is used.

This control mode is sensitive about accurate motor parameterization and requires expert knowledge in the commissioning. We strongly recommend NOT enabling this mode for regular open loop motor control applications or when expert knowledge is not available.

The advanced sensorless control has a similar control structure to the closed loop control but with Voltage Vector Control. The selection between frequency, speed, and torque control is still done with P3.1.2.1 Control Mode.

When commissioning the sensorless control function, always do these steps:

• Do identification with rotation (P1.15/P3.1.2.4 = 2).

• Set reasonable minimum frequencies (P3.3.1.1-3.3.1.4).

• Use motor stall protection (P3.9.3.1-3.9.3.4).

With an induction motor, always use start magnetization to build up rotor flux. With a PM motor, using start magnetization is highly recommended to make sure that the rotor alignment is correct.

The identification with rotation is necessary because the advanced sensorless control is sensitive about accurate motor parameterization. We recommend using minimum frequencies because continuous operation at or near zero frequency can cause instability of control and must be prevented. The motor stall protection function protects the motor if there is instability at low frequency that can cause continuous high current that increases the motor temperature.

In the speed control mode with an induction motor, especially the generator side must be considered because the flux frequency is smaller than the shaft frequency because of the slip frequency.

Use the Preset frequencies function in processes where more than 1 fixed frequency reference is necessary. There are 8 preset frequency references available. The selection of a preset frequency reference can be made with the digital input signals P3.3.3.10, P3.3.3.11, and P3.3.3.12.

The motor underload protection makes sure that there is a load on the motor when the drive operates. If the motor loses the load, a problem can occur in the process. For example, a belt can break or a pump become dry.

The motor underload protection can be adjusted with parameters P3.9.4.2 (Underload Protection: Field Weakening Area Load) and P3.9.4.3 (Underload Protection: Zero Frequency Load). The underload curve is a squared curve between the zero frequency and the field weakening point. The protection is not active below 5 Hz. The underload time counter does not operate below 5 Hz.

The values of the underload protection parameters are set in percentage of the nominal torque of the motor. To find the scaling ratio for the internal torque value, use the data in the nameplate data of the motor, the motor nominal current, and the nominal current of the drive IH. If another current than the nominal motor current is used, the precision of the calculation decreases.

It is possible to select the target input for the signal of the analog frequency reference from the available analog inputs.

When the parameter P3.1.2.1 (Control Mode) is set to Torque control open loop, the motor torque is controlled. The motor speed changes to agree with the actual load on the motor shaft. P3.3.2.7 (Torque Control Frequency Limit) controls the motor speed limit.

Find the applicable functions for digital inputs as parameters in parameter group M3.5.1. To give a digital input to a function, set a value to the correct parameter. The list of applicable functions shows in Group 3.5: I/O Configuration > #X002668 > table_yjr_rgx_k1b.

Use the joystick parameters when controlling the frequency reference or the torque reference of the motor with a joystick. To control the motor with a joystick, connect the joystick signal to an analog input and set the joystick parameters.

Use the Jogging function to override the normal control momentarily. Use this function, for example, to control the process slowly to a special status or position during maintenance. There is no need to change the control place or other parameters.

Only when the drive is in stop state, it is possible to activate the Jogging function. It is possible use 2 bi-directional frequency references. Activate the Jogging function from the fieldbus or by digital input signals. The Jogging function has a ramp time that is used always when jogging is active.

The Jogging function starts the drive at the set reference. A new start command is not necessary. The control place does not affect it.

The Jogging function can be activated from the fieldbus in bypass mode with Control Word bits 10 and 11.

Use the Input pressure supervision to make sure that there is enough water in the inlet of the pump. When there is enough water, the pump does not suck air and there is no suction cavitation. To use the function, install a pressure sensor on the pump inlet.

If the input pressure of the pump goes below the set alarm limit, an alarm shows. The setpoint value of the PID controller decreases and causes the output pressure of the pump to decrease. If the pressure goes below the fault limit, the pump is stops and a fault shows.

The Soft fill function is used to move the process to a set level at a slow speed before the PID controller starts to control. If the process does not go to the set level during the timeout, a fault shows.

It is possible to use the function to fill an empty pipe slowly and prevent strong currents of water that could break the pipe.

We recommend always using the Soft fill function when using the Multi-pump function.

The AC drive has different counters based on the operation time of the drive and the energy consumption. Some of the counters measure total values and some can be reset.

The energy counters measure the energy that is taken from the supply network. The other counters are used to measure, for example, the operation time of the drive or the run-time of the motor.

It is possible to monitor all the counter values from the PC, control panel, or fieldbus. When using the PC or the control panel, it is possible to monitor the counter values in the Diagnostics menu. When using fieldbus, it is possible to read the counter values with the ID numbers.

The timer functions make it possible for the internal RTC (real-time clock) to control functions. All the functions that can be controlled with a digital input, can also be controlled with the RTC, with time channels 1–3. It is not necessary to have an external PLC to control a digital input. It is possible program the closed and opened intervals of the input internally.

To get the best results of the timer functions, install a battery, and make the settings of the real-time clock carefully in the Start-up wizard. The battery is available as an option.

The monitoring values related to temperature input settings are only available if a B8 or BH option board is installed.

The frequency reference of the Motor Potentiometer is available in all the control places. It is possible to change the motor potentiometer reference only when the drive is in the run state.

Before or after baseline run, each measurement point can be modified by parameter. One array includes 10 points in steady state and 9 points in ramp state.

In some processes, it can be necessary to avoid some frequencies because they make problems of mechanical resonance. With the Prohibit frequencies function, it is possible to prevent the usage of these frequencies. When the input frequency reference increases, the internal frequency reference stays at the low limit, until the input frequency reference is above the high limit.

For stator winding monitoring, the motor currents are being evaluated for evolving unbalances. For this purpose, current unbalance is computed and monitored. If there are the unbalanced grid voltages, a resonance-like oscillation can occur if the motor frequency matches the grid frequency.

Start and stop commands must be given differently in each control place.

When Fire mode is active, the drive resets all faults that occur and continues to operate at the same speed until it is not possible. The drive ignores all commands from the keypad, fieldbuses, and the PC tool. It only obeys the signals Fire Mode Activation, Fire Mode Reverse, Run Enable, Run Interlock 1, and Run Interlock 2 from I/O.

The Fire mode function has 2 modes, the Test mode, and the Enabled mode. To select a mode, write a password in parameter P3.17.1 (Fire Mode Password). In the Test mode, the drive does not automatically reset the faults, and the drive stops when a fault occurs.

It is also possible to configure Fire mode with the Fire mode wizard, which can be activated in the Quick Setup menu with parameter B1.1.4.

When the Fire mode function is activated, an alarm shows on the display.

Use the feedback supervision to make sure that the PID Feedback value (the process value or the actual value) stays in the set limits. Use this function, for example, to find a pipe break and stop the flooding.

These parameters set the range in which the PID Feedback signal stays in correct conditions. If the PID Feedback signal does not stay in the range, and this continues longer than the delay, a Feedback supervision fault (the fault code 101) shows.

Use this parameter to enable the Load Drooping function. The Load drooping function enables a speed drop as a function of load. Use this function when a balanced load is necessary for mechanically connected motors. This is called static drooping. The function can also be used when a dynamic drooping is necessary because the load changes. In static drooping, the Load Drooping Time is set to 0, so that the drooping cannot decay. In dynamic drooping, the Load Drooping Time is set. The load is momentarily drooped with energy from the system inertia. This decreases the current torque spikes when the load changes suddenly.

If the motor has a nominal frequency of 50 Hz, the motor is loaded with the nominal load (100% of the torque), and Load Drooping is set to 10%, the output frequency is let to decrease 5 Hz from the frequency reference.

Use this parameter to adjust the stator voltage in permanent magnet motors.

It is possible to use this parameter only when the parameter P3.1.2.2 Motor Type has the value PM motor. If induction motor is selected as the motor type, the value is automatically set to 100%, and the value cannot be changed.

When changing the value of P3.1.2.2 (Motor type) to PM Motor, the parameters P3.1.4.2 (Field Weakening Point Frequency) and P3.1.4.3 (Voltage at Field Weakening Point) increase automatically to be equal with output voltage of the drive. The set U/f ratio does not change. This is done to prevent the operation of the PM motor in the field weakening area. The nominal voltage of the PM motor is much lower than the full output voltage of the drive.

The nominal voltage of the PM motor agrees to the back EMF voltage of the motor at nominal frequency. But in a different motor manufacturer, it can be equal to, for example, the stator voltage at nominal load.

Stator Voltage Adjust helps to adjust the U/f curve of the drive near the back EMF curve. It is not necessary to change the values of many U/f curve parameters.

The parameter P3.1.2.13 gives the output voltage of the drive in percentage of the nominal voltage of the motor at the nominal frequency of the motor. Adjust the U/f curve of the drive above the back EMF curve of the motor. The motor current increases the more the U/f curve is different from the back EMF curve.

Use this parameter to set the flying start options. The parameter Flying Start Options has a checkbox selection of values.

The bits can receive these values.

• Search the shaft frequency only from the same direction as the frequency reference

• Disable the AC scanning

• Use the frequency reference for an initial guess

• Disable the DC pulses

• Flux build with current control

The bit B0 controls the search direction. With the bit set to 0, the shaft frequency is searched in 2 directions, the positive and the negative. With the bit set to 1, the shaft frequency is searched only in the frequency reference direction. It prevents the shaft movements for the other direction.

The bit B1 controls the AC scanning that premagnetizes the motor. In the AC scanning, the system sweeps the frequency from the maximum towards zero frequency. The AC scanning stops when an adaptation to the shaft frequency occurs. To disable the AC scanning, set the bit B1 to 1. If the value of Motor Type is permanent magnet motor, the AC scanning is disabled automatically.

Use the bit B5 to disable the DC pulses. The primary function of the DC pulses is to premagnetize the motor and examine the rotation of the motor. If the DC pulses and the AC scanning are enabled, the slip frequency tells which procedure is applied. If the slip frequency is less than 2 Hz, or the motor type is PM motor, the DC pulses are disabled automatically.

The bit B7 controls the rotation direction of the injected high frequency signal, which is used in the flying start of synchronous reluctance machines. Signal injection is used to detect the frequency of the rotor. If the rotor is in a blind angle when the signal is injected, the rotor frequency is undetectable. Reversing the rotation direction of the injection signal solves this problem.
