Caution
Note1
Normal operation is possible up to AC power supply 1.5
cycle instantaneous stop. The detection of control power
supply error or Servo ready OFF is operated in 1.5 to 2
cycle instantaneous stop.
Note2
When main power supply voltage goes up or down with an
easy slope or the voltage stops instantaneously, main
circuit short voltage or main circuit phase missing may be
detected.
Note3
In case control power supply voltage +5V drops by turning
it off, the alarm can not be cleared even if detecting control
power supply error that +5V does not drop thoroughly and
returns. In this case turn off the control power supply.
Note4
When the instantaneous stop of control power becomes
long the detected control power supply error is not left in
alarm history because the condition is regarded as
shutting off the power supply and turning it on again. (If
the instantaneous stop exceeds one second, it is sure to
be regarded as power supply intercept.)
