What to do if my WEG DC Drive motor does not run?
- A
  Andrew SimonAug 2, 2025
  If your WEG DC Drive motor isn't running, there are several potential causes: * **Incorrect wiring:** Check both the power and control connections. Ensure 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 (if used):** Verify the external signal is properly connected and check the status of the speed potentiometer. * **Incorrect programming:** Ensure parameters are correctly programmed for your application. * **Fault:** Check if the inverter has been disabled due to a detected fault condition. * **Motor stall:** Reduce the motor load or increase P169 or P136/P137.

  If the motor speed on your WEG DC Drives is too high or too low, consider these potential reasons: * **Programming error (reference limits):** Verify that the values set for P133 (minimum frequency) and P134 (maximum frequency) align with the motor's specifications and the application's requirements. * **Signal of the reference control:** Examine the control signal level of the reference and review the programming (gains and offset) at P234 to P236. * **Motor nameplate:** Ensure that the motor being used is appropriate for the application's demands.

What to do if the display is OFF on my WEG DC Drive?
- M
  Megan SanchezAug 18, 2025
  If the display is OFF on your WEG DC Drive, the power supply may be the issue. Ensure the power supply is within the correct range: * **200-240 V models:** The voltage should be between 170 V and 264 V. * **110-127 V models:** The voltage should be between 93 V and 140 V.

What to do if motor speed oscillates in WEG DC Drives?
- A
  Ashley BrownAug 26, 2025
  If the motor speed oscillates in your WEG DC Drives, consider the following: * **Loose connections:** Disable the inverter, switch OFF the power supply, and carefully tighten all connections. * **Defective speed potentiometer:** Replace the speed potentiometer if it is defective. * **Variation of the external analog reference:** Determine the cause of the variation.
