Cause and
correction
Assumed cause Correction Prevention
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. Confirm the Servo Drive specifica-
tions, and perform the correct wir-
ing.
In the case where the sin-
gle-phase power supply is input
to a single- 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).
Disable the phase loss detection
when you input the single-phase
power supply to a single- and
3-phase input type Servo Drive.
The power supply voltage is low
or insufficient Improve power supply conditions
by increasing the power supply
capacity or the like. Improve power supply conditions
by increasing the power supply
capacity or the like.
Broken wiring of the main circuit
power supply input Replace the main circuit power
supply input cable. Confirm that the main circuit power
supply input cable is not broken
before use.
Servo Drive failure If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive. None
