3.2.5 If the Servomotor Fails to Start
If the servomotor fails to start or unexpected indication is given, it is recommended to undergo the
procedure described in “13.5.8 Diagnosis to be Made If the Servomotor Fails to Start” on page 13-29,
using PC Loader.
3.2.6 Shutdown
If the power is turned off with the servo-on signal turned on, the servo amplifier detects a low voltage
alarm.
•
If the power is turned off for an interval longer than the main power shutoff detection time (PA2_68)
with the servo-on signal being turned on, and if the power is supplied again, a main circuit low
voltage alarm (LVP) is detected.
•
If the power is turned on again with the servo-on signal being turned on after one second or more
since the main power shutoff detection time (PA2_68) has elapsed, the main circuit low voltage
alarm is not detected.
•
If the DC link voltage drops below about 200V and the power is restored within one second with the
servo-on signal being turned on, the main power undervoltage is detected. If the duration exceeds
one second, the main power undervoltage is not detected.
Even if the main power undervoltage alarm is detected, there is no effect on the servo amplifier.
However, do not repeat to turn the power on or off to start or stop the servomotor.
Repetitive power-on and shutdown will cause breakage to the servo amplifier.
If the operation command is turned off before the power is shut off, the main power undervoltage is not
detected.
This type of the servo amplifier does not cause the output shaft of the servomotor to coast to stop even
if an alarm reset signal is supplied.
The alarm reset signal resets alarm detection (activation of a protective function of the servo amplifier).
If the power is shut off during operation, the servo amplifier turns off the ready for servo-on [RDY]
signal to stop the internal CPU.
