4.25.7.10 Overvoltage motor cutoff
The module supply voltage is continually monitored. Its status can be read. The error "Module power supply error"
occurs when the voltage is above or below the limits.
If the supply voltage on the module rises or falls outside the limit values (e.g. due to regeneration), then the motor
output is switched off.
The outputs are reactivated as soon as the supply voltage is back in the valid range and the error bit is reset.
