The speed loop monitor is activated if the following conditions occur
simultaneously:
•
Parameter
S-0-0080, Torque/force command value
is at the
torque/force limit.
•
S-0-0080, Torque/force command value
and actual velocity have
different signs.
•
The actual velocity is higher than 20 rpm or 20 mm/min.
•
Actual acceleration and control deviation have different signs.
Cause
Remedy
Motor phases (U, V, W) interchanged so that
commutation of motor is incorrect
Check motor cable connection and correct phase
assignment, if necessary
Incorrect encoder arrangement
Correct encoder arrangement (inverting rotational
direction of encoder can possibly resolve problem)
Speed loop setting incorrect
Check speed loop setting according to Application
Manual
Commutation offset incorrect
Replace motor (in the case of MHD, MKD, MKE motors);
in the case of kit motors, make commutation settings
Motor encoder defective
Replace motor encoder (or motor)
