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.21)
→ 9.1 Memory allocation (P.30)
Electric
noise
Connect to Ground correctly.
Avoid bundling the cables.
Refer to the controller operation manual and
take appropriate measures.
→ 3.4 Mounting (P.15)
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.41)
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.11)
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.30)
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.11)
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.49)
The 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 actuator returns to
the origin correctly.
Perform the Return to Origin
position operation several times to
check the Origin position.
Take measures to make the actuator operate
normally (remove foreign matter that
interferes with the actuator movement, etc.)
Incorrect
parameters
Check that the parameter values are
appropriate and the program is
correct.
Review the maximum speed, the
maximum acceleration and the
maximum deceleration of the actuator.
Modify the parameters and test the operation.
→ 10. Settings and Data Entry (P.41)
Unsuitable
specification
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.11)
