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
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 15 ms or more time should
be maintained between the input
signals.

8.4 Controller input signal
response time
SVON time
Check if the electric actuator is
operated when the SVRE output
is turned on after the SVON
input is turned on.
When power is applied, it may take up
to 10 seconds (max. 20 sec.) from
SVON input to SVRE output
depending on the electric actuator
position. Command operation after
SVRE output is turned ON.
Alarm
condition
Is controller alarm generated?
Refer to the controller operation
manual, and take appropriate
measures. Take appropriate measures
based on the operation manual.

12. Alarm Detection
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.

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
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.
