What to do if Danfoss DC Drives display is dark?
- J

  If the Danfoss DC Drives display is dark and there's no function, several issues could be the cause. First, check the input power source to ensure it's properly connected. Next, verify that fuses haven't blown or the circuit breaker hasn't tripped, and follow the recommendations provided. Inspect the LCP and connection cable, and replace if faulty. Ensure there are no shortcuts on the control voltage (terminal 12 or 50) or at control terminals, and wire the terminals properly. Confirm you're using the correct LCP (LCP 101 (P/N 130B1124) or LCP 102 (P/N 130B1107)). Try adjusting the contrast by pressing [Status] + [?]/[?]. If the display (LCP) is defective, replace it. If the internal voltage supply fault or SMPS is defective, contact supplier.

Why is the display on my Danfoss VLT AutomationDrive FC 300 intermittently turning off?

  Derrick GilbertAug 11, 2025
  An intermittent display on Danfoss DC Drives can be caused by an overloaded power supply (SMPS) due to improper control wiring or a fault within the adjustable frequency drive. If the display stays lit, the problem is likely in the control wiring; check for shorts or incorrect connections. If the display continues to cut out, follow the procedure for a dark display.

  If the Danfoss DC Drives display is dark or has no function, several issues could be the cause. First, check the input power source. Also, check for missing or open fuses, or a tripped circuit breaker. Ensure that the LCP has power, and if it doesn't, replace the faulty LCP or connection cable. Also, verify that there isn't a shortcut on the control voltage (terminal 12 or 50) or at the control terminals, and if there is, wire the terminals properly. Confirm that you're using the correct LCP (LCP 101 (P/N 130B1124) or LCP 102 (P/N 130B1107)). Check the contrast setting by pressing [Status] + [?]/[?]. If the display is still defective, replace the LCP or connection cable. If the SMPS is defective, contact your supplier.
