<Countermeasure> Make sure that the voltage supplied to the control
power (C24V) of the controller is appropriate.
Caution
If a single power supply is used for both the control power and the
motor power, or the power supply is "inrush-current control type", a
power voltage drop may be caused due to a voltage drop during
acceleration/deceleration.

(When the servo motor is turned ON (
“SVON” turns ON) for the first time
after the power is applied, the actuator needs to move a little to find the
motor phase. However, if this actuator movement is prevented, this alarm
will be activated.)
<Countermeasure> Make sure there are no obstructions that interfere with the
actuator movement and then turn ON the servo motor (
“SVON” turns ON).
