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 the
origin correctly.
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.)
Inappropriate
basic
parameters
Check that the parameter values
are appropriate and the program
is correct.
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
Inappropriate
specifications
Check that the combination of
the electric actuator and
controller is correct?
If the blank controller is used,
check that the written data is
identical with the actuator used.
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 electric
actuator does
not move
correctly.
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 PWR
controller input and the parallel I/O signal
power supply.

6.4 Parallel I/O Wiring Example P.36
Inappropriate
specifications
Check that the combination of
the electric actuator and
controller is correct?
If the blank controller is used,
check that the written data is
identical with the actuator used.
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.
Influence of a
magnetic
force
Check if there is equipment
which generates the magnetic
force, such as a magnet or
electro-magnetic coil around the
actuator.
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.
Signal timing
Check the timing of the signal
from the PLC to the controller.
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
time P.46
Data writing
failure
Is the data (step data or
parameters) written correctly?
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.
