What to do if the motor is not running on a Danfoss Controller?
- DDavid EsparzaAug 25, 2025
If your Danfoss Controller's motor isn't running, first ensure the motor is connected and check the service switch. If you're using a 24 V DC option card, make sure mains power is applied to run the unit. If the LCP is stopped, press [Auto On] or [Hand On], depending on the operation mode, to start the motor. Ensure a valid start signal is applied to initiate motor operation. If the motor coast signal is active, apply 24 V on terminal 27 or program this terminal to 'No operation'. Also, verify that the reference signal source is correctly programmed, checking settings in parameter group 3-1* References, wiring, scaling of terminals, and the reference signal itself.
