How can motor stalling be reduced on an ATV320 besides adjusting IR compensation?
Resolution:
Motor stalling can be caused by mechanical issues with the motor or driven load, excessive load, or a speed loop that is not properly adjusted for the application.
Before adjusting the drive parameters, verify that there are no mechanical issues with the motor or driven load. Check that the motor and load can rotate freely and that there is no binding, excessive friction, blockage, or other condition that could cause excessive motor load.
If the mechanical system is operating correctly, the speed loop can be tuned based on the selected motor control type (CtT):
- When CtT = Standard, adjust the SPGU parameter.
- When CtT = SVCV, adjust the SPG and SIT parameters.
Proper speed loop adjustment can help improve motor response and reduce stalling. Make parameter changes carefully and verify motor operation under actual load conditions.
