40-55 Modulation Index
Default value: 100%
Setup:
All setups
Data type: Uint8
This parameter is for IPM and SPM motors in VVC+ control principle only.
Activate this parameter by setting parameter 14-03 Overmodulation to [2] User Defined. Use this parameter to set the maximum
modulation index and thus trim the application, especially if running with high-power motors without sine-wave filters. Increasing the
maximum modulation index increases the motor voltage and improves efficiency and stability. Setting the modulation index too high
may lead to torque ripples on the motor shaft.
40-56 Rotor Position Estimation Gain
Default value: 100%
Setup:
All setups
Data type: Uint16
When running IPM with high speed, high load, and low mains voltage, there is an increased risk of nuisance alarms. To reduce the risk of
alarms, decrease the value, which then increases control stability.
