30-21 High Starting Torque Current [%]
Default value: Size related
Setup: All setups
Data type: Uint32
Set the high starting current that should be applied for the time specified in parameter 30-20 High Starting Torque Time. The increased
current will improve the starting torque and starting performance in demanding applications. The high starting torque current is valid
for VVC+ and flux in speed open loop. The parameter can be used with the following motors:
SPM

30-22 Locked Rotor Protection
Default value: [0] Off
Setup: All setup
Data type: Uint8
Available for PM motors only, in flux sensorless mode and VVC+ open-loop mode.

30-23 Locked Rotor Detection Time [s]
Default value: Size related
Setup: All setups
Data type: Uint8
Time period for detecting the locked rotor condition. A low parameter value leads to faster detection.
30-24 Locked Rotor Detection Speed Error [%]
Default value: 25%
Setup:
All setups
Data type: Uint32
Detects locked rotor condition for SPMSM at high speed.
