八、Protective function
1) Short circuit protection
When a phase-to-phase short circuit occurs or an internal overcurrent occurs in the driver, the
red light of the driver flashes once and blinks repeatedly within 3 seconds. At this point, the fault
must be discharged and the power-on reset should be resumed.
2) Overvoltage protection
DM542 When the input voltage is higher than 60V, the red light of the driver flashes twice,
and it flashes repeatedly within 3 seconds. At this point, the fault must be discharged and the
power-on reset should be resumed.
3) Motor open circuit protection
When the motor is open or not connected, the drive driver flashes red 4 times and flashes
repeatedly within 3 seconds. At this point, the fault must be discharged and the power-on reset
should be resumed.
