The active speed of rotation is greater than the maximum speed of rotation of the motor that means 111.1% of MaxVel is exceeded.

An MH3 motor indicating a diagnostic message 8122 Shutdown due to velocity limit can also provoke the diagnostic messages 8107 Overcurrent or 8119 Power stage short-circuit / ground fault.

Cause

Solution

Error occurs on a CAM movement function (for example, MultiCam()) due to incorrect curve or profile data.

Verify and correct if necessary the curve data and program.

Jumps occurred in the master encoder.

Verify and correct if necessary the master encoder.

An error occurred on a CAM movement function due to an incorrect position manipulation, for example, FC_SetposSingle() function.

Verify and correct if necessary the program.

Detected hardware error: Commutation error, that is, the motor encoder (SinCos) is not calibrated or leveled.
