What to do if desired input is not obtained on Panasonic GM1 Controller?
- EErin WatsonSep 9, 2025
If the desired input is not obtained, consider both software (program or I/O allocation) and hardware (wiring or power supply) factors. Here’s a troubleshooting process: 1. If the input display LED is unlit, proceed to the next step. If it is lit, skip to step 4. 2. Recheck the wiring of the input devices for loose terminals. 3. Check if the correct voltage is applied to the input terminals. If voltage is present, there may be an abnormality in the unit’s input part. If voltage is absent, there may be an issue with the power supply or the input device. 4. Use the GM Programmer to monitor the input state. If the monitored state is OFF, there's probably an issue with the input unit. If the monitored state is ON, the program may have an abnormality.
