    Hi!
    I have the exact same alarms on my Mazak VTC-30C with Mazatrol M-Plus. Did you solve this problem?
    My 24V power supply failed. I repaired it, but the following errors remain and cannot be reset.
    2 EMERGENCY STOP
    2 EMERGENCY STOP
    382 SPINDLE POWER CUT MALF.
    383 PLC EMERGENCY STOP RELAY FAULT
    385 ESTOP SAFETY RELAY FAULT
