How to troubleshoot a dark or non-functional display on Danfoss DC Drives?

M
Matthew BarnesJul 31, 2025
If the Danfoss DC Drives display is dark or has no function, check the input power source. Also, check for any missing or open fuses, or a tripped circuit breaker. Ensure the LCP is receiving power, and if faulty, replace the LCP or connection cable. Verify that there are no shortcuts on the control voltage (terminal 12 or 50) or at the control terminals, and wire the terminals correctly. Use only LCP 101 (P/N 130B1124) or LCP 102 (P/N 130B1107). Adjust the contrast by pressing [Status] + [?]/[?]. If the display (LCP) is defective, replace it. For an internal voltage supply fault or defective SMPS, contact your supplier.

What to do if the Danfoss FC 102 DC Drives display is intermittent?

R
Ricky JacksonAug 16, 2025
If the Danfoss DC Drives display is intermittent, it might be due to an overloaded power supply (SMPS) caused by improper control wiring or a fault within the frequency converter. If the display stays lit, check the control wiring for shorts or incorrect connections. If the display continues to cut out, follow the procedure for a dark display.
