movable
stroke
Was the stopper of electric
actuator adjusted?
Check the set position of the stopper of
electric actuator.
Perform the stroke study when adjusting
the stopper of electric actuator.
→ 7.1(3) Stroke study
→ 7.1(7) Intermediate position setting
After performing Stroke study,
were all the intermediate positions
re-registered?
After learning the stroke, be sure to
register all intermediate positions (position
numbers 3 to 14 (E)) again.

Wiring fault
Is the wiring connected correctly?
Check if the wiring is connected correctly
or if there is broken wire or short-circuit by
referring to this Operation Manual.
Correct the wiring and check that the input
/ output of each signal is correct.
Separate the power supply for the CN1
controller and the CN4 I/O signal power
supply.

Inappropriate
specifications
Check that the combination of the
electric actuator and controller is
correct?
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.

Signal
timing
Check the timing of the signal from
the PLC to the controller.
PLC processing delay and controller scan
delay are generated. Please ensure an
interval of 15ms (30 ms if possible) or
more between input signals, and maintain
the signal state.

te step data
Is the operation pattern
trapezoidal?
In case of such operation, the electric
actuator may start slowing down before it
reaches the maximum speed. Modify the
setting to make the moving distance
longer or the acceleration larger.

Inappropriate
specifications
Check that the combination of the
electric actuator and controller is
correct?
Check if the electric actuator is
operating within the specification
range.
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.
Check if the operating condition of the
electric actuator is within the specification
range.

Speed
change in
auto mode
Change the value of the speed or
acceleration switch in auto mode.
Go to speed adjustment in auto mode to
change the speed and acceleration.
→ 7.2 Setting of the speed and the
acceleration
Voltage
drop
Check if there has been any
temporary voltage drop in the
power supply.
(If there is a temporary voltage
drop in the power supply, the EMG
terminal of CN1 power connector
will turn OFF so the electric
actuator will stop. However, this
stop will be released when the
voltage recovers.)
There is a possibility of a momentary
voltage drop because the capacity of the
power supply is insufficient, or the power
supply has inrush current suppression
type.
