Troubleshooting
Remedial action
• Remove the cause of the
stiff movement or blockage
• Check the encoder cable
and replace, if necessary
• Replace the encoder
If the stepper motor is not
supplied with current:
• Check the stepper motor
cable and replace,
if necessary
• Replace the stepper motor
• Remove the cause of the
stiff mechanical movement
or blockage
• Check the connection of
the encoder cable and
replace, if necessary
• Check connection cables
• Check stepper motor for
stiff movement
• Perform a software update
• Replace the control
• Replace the stepper motor
• Check the mains voltage
• Remove the blockage or
the cause of the stiff
movement
• Replace the stepper motor
• Replace the control
• Correct the cause of not
moving freely
• Replace the stepper motor
• Replace the control
