POWER
Lit while power flows between P and N terminals.
REGEN
Lit during regeneration operation.
ALARM-REGEN
Lit for regeneration resistance disconnection or regeneration transistor damage.
ALARM-OV
Lit when overvoltage occurs.
Note 1. When the error detection function operates, an alarm is output from the Unit.
Note 2. Create a sequence so that the power supply (R-T) to the Servo Driver is cut off when an alarm
is generated.
Note 3. When the error detection function operates and the Servo Driver’s power supply is cut off, the
Regeneration Unit won’t be restored to its normal status until 2 to 3 seconds have elapsed,
even if the power supply is turned on again. (Normal status is restored after the electrolytic
capacitor in the Servo Driver has been discharged and the voltage between P and N drops.)
Note 4. Does not conform to EC Directives.
