The electric
actuator does
not move
correctly.

How to diagnose the trouble
cause
If it is a pushing operation,
repeat return to origin operations
Incorrect
several times to check if the
origin position
electric actuator returns to the
origin correctly.
Inappropriate Check that the parameter values
basic are appropriate and the program
parameters is correct.
Check that the combination of
the electric actuator and
controller is correct?
Inappropriate
If the blank controller is used,
specifications
check that the written data is
identical with the actuator used.
Is the wiring connected
Wiring fault
correctly?
Check that the combination of
the electric actuator and
controller is correct?
Inappropriate
If the blank controller is used,
specifications
check that the written data is
identical with the actuator used.
Check if there is equipment
Influence of a which generates the magnetic
magnetic force, such as a magnet or
force electro-magnetic coil around the
actuator.
Check the timing of the signal

from the PLC to the controller.
Is the data (step data or

parameters) written correctly?
failure
Perform the return to origin position
operation several times to check the
origin position.
Take measure to make the electric
actuator operates normally (remove
foreign matters that interferes with the
electric actuator movement, etc.)
Check the max. speed, acceleration
speed, and deceleration speed of the
electric actuator and be sure to input the
correct parameters.
→ 7. Setting Data Entry P.37
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.
→ 3. Product Specifications P.16
If the blank controller is used, write the
data, which is identical with the product
number of the actuator used.
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 PWR
controller input and the parallel I/O signal
power supply.

Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the
controller.
→ 3. Product Specifications P.16
If the blank controller is used, write the
data, which is identical with the product
number of the actuator used.
The equipment, which generates the
magnetic force, should be kept away
from the motor.
For example, keep 40 mm minimum
distance from the cylinder with auto
switch.
Both PLC processing delay and
controller scan delay are generated.
Ensure that 2 times or more of the
communication cycle should be
maintained between signals.
→ 8.4 Controller input signal response
One of the following actions occurred
during data writing (while the power
supply LED (green) was on).
・Turn off the controller input power supply
・Disconnected/ connected cables.
Input correct data (step data, parameter)
again and confirm operation.
