Undervolt-
age (insuffi-
cient voltage
between P
and N)
The main circuit power
supply voltage fell below
the operation guaran-
tee range during Servo
ON.
Incorrect wiring of the
main circuit power sup-
ply
If the power supply cables are not
wired to the main circuit power sup-
ply terminals (L1, L2, L3), connect
them.
The low power supply
voltage is applied to the
Servo Drive.
Increase the power supply capacity
if it is small. Measure the applied
power supply voltage, and apply the
voltage according to the specifica-
tion.
The long time was set in
Momentary 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.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
When there is a failure in inrush
current prevention circuit, in some
cases, this error occurs.
01 Main Circuit
Power Sup-
ply Phase
Loss Error
The phase loss of the
main circuit power sup-
ply was detected.
Incorrect wiring, for
example the single-
phase power supply is
input to a 3-phase input
type Servo Drive.
Confirm the Servo Drive specifica-
tions, and perform the correct wir-
ing.
In the case where the
single-phase power
supply is input to a sin-
gle- and 3-phase input
type Servo Drive, the
phase loss detection is
enabled.
Set Main Circuit Power Supply -
Phase Loss Detection Enable
(4320-02 hex) to 0 (disabled).
The power supply volt-
age is low or insufficient.
Improve power supply conditions by
increasing the power supply capac-
ity or the like.
Broken wiring of the
main circuit power sup-
ply input
Replace the main circuit power sup-
ply input cable.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
