Stability
Symptom Cause Remedy
Motor runs away when the loop is
closed.
Wrong feedback polarity. Invert the polarity of the loop by
inverting the motor leads (brush type)
or the encoder.
Motor oscillates. Too high gain or too little
damping.
Decrease KI and KP. Increase KD.
Operation
Symptom Cause Remedy
Controller rejects command.
Responded with a ?
Invalid Command Interrogate the cause with TC or
TC1.
Motor does not complete move. Noise on limit switches stops the
motor.
To verify cause, check the stop
code (SC). If caused by limit
switch noise, reduce noise.
During a periodic operation, motor
drifts slowly.
Encoder noise Interrogate the position
periodically. If controller states
that the position is the same at
different locations it implies
encoder noise. Reduce noise. Use
differential encoder inputs.
Same as above. Programming error. Avoid resetting position error at
end of move with SH command.
