motor not moving but drawing current

[msingh]

Hi,

equipment:

NUCLEO-F303RE

X-NUCLEO-IHM07M1

Maxon motor 496653 with 5.8:1 gear ratio

Motor Profiler 5.4.4

MotorControl Workbench 5.4.4 (MCWB)

STM32CubeMX 5.5

STM32CubeIDE 1.4.0

Project details: I have created a position control project following the AN5464 and I am attempting to drive the motor.

Issue: Motor not able to rotate. When the motor should be rotating it drawn current gradually increments up to +-400mA without achieving any movement. I have tried using the MCWB which doesn't show any faults and I can also see the measured currents (IQ and Flux) changing but the measured speed remains to 0 (as the motor is not rotating at all).

Thoughts: I am guessing there is an issue with either the position or speed PIDs. I have managed to create a project using the IHM08M1 and I have attempted to use the same PID settings but they didn't help.

I would appreciate anyone sharing their thoughts.

Kind Regards
