3. SIGNALS AND WIRING
3.3 Alarm occurrence timing chart
CAUTION
When an alarm has occurred, remove its cause, make sure that the operation
signal is not being input, ensure safety, and reset the alarm before restarting
operation.
When an alarm occurs in the servo amplifier, the base circuit is shut off and the servo motor is coated to a
stop. Switch off the main circuit power supply in the external sequence. The alarm is deactivated by
switching control circuit power off, then on or by turning on the error reset command or CPU reset
command from the servo system controller. However, it cannot be deactivated unless the cause of the
alarm is removed.
Note 1. Shut off the main circuit power as soon as an alarm occurs.
2. At overcurent (32) alarm occurrence, the dynamic brake does not operate. The servo motor coasts to a stop.
3. When control circuit power switches off, the dynamic brake does not operate. The servo motor coasts to a stop.

(1) Overcurrent, overload 1 or overload 2
If operation is repeated by switching control circuit power off, then on to reset the overcurrent
(32), overload 1 (50) or overload 2 (51) alarm after its occurrence, without removing its cause,
the servo amplifier and servo motor may become faulty due to temperature rise. Securely
remove the cause of the alarm and also allow about 15 minutes for cooling before resuming
operation.
(2) Instantaneous power failure
Undervoltage (10) occurs if power is restored after a 40ms or longer power failure of the control
circuit power supply or after a drop of the bus voltage to or below 20VDC. Control circuit power
switches off if it has failed, is not restored, and remains failing. When the power failure is reset
in this state, the alarm is reset and the servo amplifier returns to the initial state.
