Cause and
correction
Assumed cause Correction Prevention
Incorrect wiring of the main cir-
cuit power supply
If the power supply cables are not
wired to the main circuit power
supply terminals (L1, L2, L3), con-
nect them.
Check the wiring of the main circuit
power supply before use.
The low power supply voltage is
applied to the Servo Drive
Increase the power supply capac-
ity if it is small. Measure the
applied power supply voltage, and
apply the voltage according to the
specification.
Apply the voltage appropriate for
the Servo Drive.
The long time was set in Momen-
tary Hold Time and the voltage
was decreased momentarily
Remove the cause that momentar-
ily decreased the voltage.
Set a short time in the Momentary
Hold Time so as not to detect this
error due to a momentary
decrease in voltage.
Set an appropriate value in the
Momentary Hold Time.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
