The motor excitation currents d-axis and q-axis are controlled separately. Torque
compensation affects q-axis current only.
Compensation voltage= q-axis voltage compensation (calculated by q-axis current) x C3-00
Adjustment:
Normally there is no need to change this parameter setting. However, adjust this setting by
scaling of 0.05 in the following situations.
· Increase the setting when using a long motor cable
· Decrease the setting when the motor oscillates
· During running at low speed, adjust C3-00 to keep the output current below the drive
rated current
Note:
· Do not change the setting in Sensorless Voltage Vector Control as it will reduce the torque accuracy.
