The control power supply voltage within the driver is out of a range.
<Countermeasure>
Make sure that the voltage supplied to the control power (C24V) of the driver
is appropriate.
If one power supply is commonly used for the control power and the
motor power, or the power supply is ”inrush current restraining type”, a
power voltage drop may be caused due to a voltage drop during the
acceleration/deceleration.

Also, a regenerative electric power may be generated to cause an alarm due
to the method of operation of the electric actuator.
<Countermeasure>
Make sure that the operating conditions are within the specifications.
Please refer to the manual or the catalogue of the electric actuator for the
method of operation of the electric actuator.
<Contents>
The output current accumulated value exceeds the specified value.
<Countermeasure>
Check whether the movement of the electric actuator is obstructed.Also
confirm whether the electric actuator load, speed, acceleration and
deceleration are within the specification range of the electric actuator.
<Contents>
Failed to reach to the set position within the set time limit during origin operation,
Move operation or JOG operation. This alarm is not generated by operation
triggered by pulse signal.
<Countermeasure>
Eliminate any obstructions that interfere with the electric actuator
movement. Also, make sure that the load, speed, acceleration and
deceleration are within the range of the electric actuators.
<Contents>
This occurs when communication is interrupted while operating with the
controller setting kit or the teaching box.
<Countermeasures>
Do not remove the cable during operation by the controller setting kit or
teaching box.
<Contents>
Abnormality in communication with the encoder.
<Countermeasure>
Check the connection of the actuator cable.
<Contents>
Unable to find the motor phase within the set time.
(When the servo motor is turned on (SVON is turned on) first time after the
power is applied, the electric actuator needs to move a little to find the motor
phase. However, if this electric actuator movement is prevented, this alarm
will be activated.)
