Push [POWER OFF].
Set the main circuit breaker to the OFF position.
Lock the main circuit breaker. Use an approved lock with an approved safety tag.
Danger: If the voltage indicator light is on, do not touch the electrical components. The high voltage in the electrical cabinet can kill you. Wait for the voltage indicator LED to go off fully.

|Symptom||Possible Cause||Corrective Action|
Alarm 123 SPINDLE DRIVE FAULT
Alarm 119 OVERVOLTAGEAlarm 292 HIGH VOLTAGE POWER SUPPLY FAULT
Alarm 650 DC BUS OVERVOLTAGEAlarm 444 REGEN REMAINED ON TOO LONG
Alarm 237 SPINDLE FOLLOWING ERRORAlarm 647 REGEN LOAD SHORTED
|The REGEN load is open or has a short circuit.||Measure the REGEN resistors.|
|The Vector drive is defective.||Chek the REGEN circuit at the vector drive.|
|The REGEN elements glow red/overheat when the machine is idle and is in [EMERGENCY STOP]
or Alarm 444 REGEN REMAINED ON TOO LONG
|There is a problem with the incoming AC power.||Measure the incoming AC Power.|
|The REGEN elements glow red/overheat when the machine is idle, and the servos are enabled. The symptom disappears when the [EMERGENCY STOP] is pressed,
or Alarm 444 REGEN REMAINED ON TOO LONG
|There is a short on any of the servo motors and/or spindle motor.||Measure the resistance to the servo motors and the spindle motor.|
|Lathes: The REGEN elements glow red/overheat when the machine runs constant surface speed G96 or when the spindle decelerates after a new chuck or part was installed.||The deceleration/acceleration cycles are too aggressive.||Review and reduce the spindle speed of acceleration/deceleration cycles.|
Check each one of the servo motors and spindle motor. Measure the resistance from each one of the motor cables to chassis. Make sure that each one of the wires measures open to chassis. With the machine power off, disconnect all of the cables from each one of the amplifiers and measure the resistance of each terminal to the amplifier enclosure. Each terminal must measure open to the amplifier enclosure.
Review and reduce the spindle speed of acceleration/deceleration cycles.
Make sure the deceleration/acceleration cycles are not too aggressive during G96 Constant Surface Speed cycles.
Add short dwell times between passes.
