Cause : Undervoltage when opening the brake comes when the brake is being opened, it is detected that the power supply voltage is less than 24 V - 10% = 21.6V.
Alarm value (r2124, interpret decimal): Supply voltage fault [0.1 V].
Example: Alarm value = 195 --> voltage = 19.5 V
- Check the 24 V voltage for stability and value.
