TORQUE CONTROL IN OPEN LOOP CONTROL
P3.3.2.8.1 OPEN LOOP TORQUE CONTROL MINIMUM FREQUENCY (ID 636)
Use this parameter to set the output frequency limit below which the drive operates in the
frequency control mode.
P3.3.2.8.2 OPEN LOOP TORQUE CONTROL P GAIN (ID 639)
Use this parameter to set the P gain for the torque controller in the open loop control mode.
The P Gain value 1.0 causes a 1 Hz change in the output frequency when the torque error is
1% of the motor nominal torque.
P3.3.2.8.3 OPEN LOOP TORQUE CONTROL I GAIN (ID 640)
Use this parameter to set the I gain for the torque controller in the open loop control mode.
The I Gain value 1.0 causes the integration to reach 1.0 Hz in 1 second when the torque error
is 1% of the motor nominal torque.
10.4.4
TORQUE CONTROL IN ADVANCED SENSORLESS CONTROL
P3.3.2.9.1 SENSORLESS TORQUE CONTROL P GAIN (ID 1731)
Use this parameter to set the P gain for the torque controller in the sensorless control mode.
The P Gain value 1.0 causes a 1 Hz change in the output frequency when the torque error is
1% of the motor nominal torque.
This parameter is always active in sensorless torque control.
P3.3.2.9.2 SENSORLESS TORQUE CONTROL I GAIN (ID 1732)
Use this parameter to set the I gain for the torque controller in the sensorless control mode.
The I Gain value 1.0 causes the integration to reach 1.0 Hz in 1 second when the torque error
is 1% of the motor nominal torque.
This parameter is always active in sensorless torque control.
10.4.5
PRESET FREQUENCIES
You can use the Preset frequencies function in processes where more than 1 fixed frequency
reference is necessary. There are 8 preset frequency references available. You can make the
selection of a preset frequency reference with the digital input signals P3.3.3.10, P3.3.3.11,
and P3.3.3.12.
P3.3.3.1 PRESET FREQUENCY MODE (ID 182)
Use this parameter to set the logic of the digital input preset frequencies.
With this parameter, you can set the logic which one of the preset frequencies is selected
into use. There is a selection of 2 different logics.
The number of preset speed digital inputs that are active defines the preset frequency.
