Voltage drop
Check for a temporary
voltage drop in the power
supply.
(When a voltage
dropoccurs, the EMG
terminal of the CN1 power
connector will turn OFF
and the electric actuator
will stop. However, this
stop will be released when
the voltage recovers).
A momentary voltage drop may have
occurred because the power supply
capacity is inadequate or the power supply
is an inrush current suppressor type.

Inappropriate
specifications
Check that the
combination of the electric
actuator and driver is
correct?
Check if the product number of the used
electric actuator matches with the electric
actuator which is applicable to the driver.

Signal timing
Check the timing of the
signal from the PLC to
the driver.
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 driver scanning delays can occur.

signal
Pushing
operation
Check that the TLOUT
output is ON during a
pushing operation.
In any of the following conditions, the
TLOUT signal is turned OFF.
1. Alarm sounds: When an alarm sounds,
turn OFF the TL input, and then turn it
ON again.
2. Return to origin command: During return
to origin, do not turn ON the TL input.
Also, if you command a return-to-origin
during pushing, turn OFF the TL input
and then turn it ON again.
3. Do not turn on TL input while the servo is
OFF (SVRE output is OFF). Signal is not
recognized.
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 driver alarm generated?
Refer to the driver operation manual, and
take appropriate measures. Take
appropriate measures based on the
operation manual.
