Al-1323 (Input Power Overvoltage (Conv)) - YASKAWA Motoman UP6 Instructions Manual

AL-1323 (INPUT POWER OVERVOLTAGE (CONV))

Excessive input-voltage of SERVOPACK may damage the regenerative resistor.
CAUTION
Before checking the wiring connections, turn
OFF the control power supply.
Use a tester to confirm that all the LEDs on
the SERVOPACK and converter are unlit and
that no charged electricity remains.
(It may take a few minutes until all the
electricity is discharged.)
