What to do if my WEG DC Drives motor does not run?

  Krista CastilloJul 28, 2025
  If your WEG DC Drives motor isn't running, there are several potential causes to investigate: * **Wiring:** Ensure the power and control connections are correctly wired. Specifically, check that the digital inputs (DIx) programmed for Start/Stop, General Enable, or No External Fault are connected to GND (pin 5 of the control connector XC1). * **Analog Reference:** Verify that the external signal is properly connected and check the status of the speed potentiometer, if one is being used. * **Programming:** Confirm that the parameters are correctly programmed for your specific application. * **Fault:** Check if the drive has been disabled due to a detected fault condition. * **Motor Stall:** Try reducing the motor load, or increase the values of parameters P169 or P136/P137.

How to fix motor speed that is too high or too low on WEG CFW-10 EASYDRIVE?
- J
  joshuanguyenAug 19, 2025
  If the motor speed is too high or too low on your WEG DC Drives, check the following: * **Programming Error:** Verify that the values of parameter P133 (minimum frequency) and P134 (maximum frequency) are appropriate for the motor and application. * **Reference Control Signal:** Check the control signal level of the reference and the programming (gains and offset) at parameters P234 to P236. * **Motor Nameplate:** Ensure that the motor being used meets the requirements of the application.
