Voltage
drop
Check for a temporary voltage
drop in the power supply?
There is a possibility of a momentary
voltage drop because the capacity of the
power supply is insufficient, or if the power
supply has “inrush current suppression
type
”.
→ 3.1 Basic specifications
Inappropriate
specifications
Check if a product with a suitable
specification was selected.
Reconfirm the combination of the
power supply and the electric
actuator and controller.
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.

Servo on
time
When the power supply for the
motor is applied (or STOP input is
turned off), commandscan be
given after ALARM output is ON?
Just after the motor power is supplied, it
may take 10 seconds until ALARM output
depending on the
electric actuator
position. Command operation after
ALARM output is turned ON.
Alarm
occurring
Is the controller alarm occurring?
Refer to the instruction manual of the
controller and confirm the type of alarm.
Take appropriate measures according to
the contents.
→ 11. Alarm Detection
Command
the position
number
repeatedly
Same position number specified?
The operation is not performed when the
position number of the current stop
position is specified repeatedly. There is
no operation start either when the position
number to which the current stop position
number is registered is specified.
Check if the position number specified
before operation, the position number
which specifies the position and
operation, and the registered position
number are not overlapped.
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.
→ 8.5 Response time for the controller
input signal
The electric
actuator
does not
move to the
correct
position.
Incorrect
origin
position
If it is a pushing operation, repeat
return to origin operations several
times to check if the electric
actuator returns to origin correctly.
Perform the return to origin position
operation several times to check the origin
position.
Take measures to make the electric
actuator operate normally (remove foreign
matter that interferes with the actuator
movement, etc.)
Change of
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.
→7.1(7) Intermediate position setting
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.
