Operation stops
intermittently
Incorrect
wiring
Is the wiring connected
correctly?
Refer to the controller operation
manual to confirm wiring, and
check for broken wires and
short-circuits.
Correct the wiring so that the
input/output of each signal is performed
appropriately.

5. External Connections (P.20)

9.1 Memory allocation (P.29)
Electric
noise Connect to Ground correctly.
Avoid bundling the cables.
Refer to the controller operation manual
and take appropriate measures.
→
3.4 Mounting (P.17)
Incorrect
parameters
Check that the parameter
values are correct.
Also, check the cables are not
bundled.
Take appropriate measures according
to this manual.

10. Settings and Data Entry (P.38)
Voltage
drop
Check for a temporary voltage
drop in the power supply?
(If there is a temporary voltage
drop in the power supply, the
“EMG” signal from the PWR
connector
will turn OFF so the
actuator will stop. However, this
stop will be released when the
voltage recovers.)
There is a possibility of a momentary
voltage drop because the capacity of
the power supply is insufficient, or if the
power supply is "inrush-current control"
type.
If necessary, replace the power supply.
→
3. Specifications (P.13)
Failure of
pushing
operation.
Check that “INP” turns ON
during a pushing operation.
(If completion of the pushing
operation is detected by “INP”,
the PLC cannot confirm
completion)
Check “INP” signal before the energy
saving mode is turned ON.
→
9.1 Memory allocation (P.29)
Unsuitable
spec.
Check if the controller’s
specifications are appropriate,
the power supply is suitable and
the controller is compatible with
the actuator.
Take appropriate measures according
to this manual.
→
3. Specifications (P.13)
Signal
timing Check the timing of the signal
from the PLC to the controller.
Set the interval time between signals to
more than twice the communication
cycle time, when the signals are to be
continuously input, because PLC
processing delays and controller
scanning delays can occur.
→
11.4 Controller input signal
response time (P.46)
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 an
operation after SVRE output is turned
ON.
Alarm
condition
Is controller alarm generated?
Refer to the controller operation manual,
and take appropriate measures based
on the operation manual.
