Move
occasionally
The pushing
operation
defective.
Check during pushing operation
the INP output signal is turning
on.
(On completion of pushing the
operation the output INP signal is
generated, the PLC cannot
confirm the completion of
driving.)
If the controller version is below SV1.00
The pushing force is reduced when the
energy saving mode is turned on. If the
pushing force is reduced to a value less
than the value in step data “trigger LV”
the INP output signal is turned off.
Check the INP output signal before the
energy saving mode is turned on.
→ 6.3 The parallel I/O signal is detailed
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.
Leave an interval of a minimum of 15 ms
(recommendation is 30 ms) between
input signals and maintain the state of
the signal for a minimum of 15 ms
(recommendation is 30 ms), because
PLC processing delays and controller
scanning delays can occur.
→ 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?
Check if the product number of the used
electric actuator matches with the
electric actuator which is applicable to
the controller.
