occasionally.
Voltage drop
Check if there has been any
temporary voltage drop in the
power supply.
(If there is a temporary voltage
drop in the power supply, the
EMG terminal of CN1 power
connector will turn OFF so the
electric 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 the power
supply has inrush current restraining
specification.

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.

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.

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.
