10 Troubleshooting and remedial
actions
During actuator operation, the actuator or driver may fail to function properly due to
an improper speed setting or wiring. When the actuator cannot be operated correctly,
refer to the contents provided in this section and take appropriate action. If the
problem persists, contact your nearest office.
If ALARM LED is not blinking
If the actuator does not operate properly even though the ALARM LED is not
blinking, refer to the table below:
Phenomenon
Possible cause
Remedial action
•
The actuator is not
excited.
•
The actuator can be
turned with the hands.
C.OFF input is “ON.”
Turn the C.OFF input to “OFF”
and confirm that the actuator is
excited.
Bad connection for CW
or CCW input.
•
Check the connections of the
controller and driver.
•
Review the specifications
(voltage and width) for the input
pulse.
In 2-pulse input mode,
the CW and CCW pulse
inputs are both “ON” at
the same time.
Input the pulse signal either to the
CW or CCW input. Make sure the
terminal with no input is set to
“OFF.”
The actuator does not
run.
In 1-pulse input mode,
the pulse signal is
connected to the DIR.
input.
Connect the pulse signal to the
PLS input.
When 2-pulse input
mode is selected, the
CW and CCW pulse
inputs are connected in
reverse.
Connect the CW pulse input to
the CW pulse input and CCW
pulse input to CCW pulse input.
The actuator rotates in
the direction opposite
that which is specified
(The CW and CCW
inputs provided as
driver input signals
indicate the opposite
directions to the output
table’s direction of
rotation).
When 1-pulse input
mode is selected, the
DIR. input is set in
reverse.
Set to “ON” when setting the CW
direction or “OFF” when setting
the CCW direction.
Actuator operation is
unstable.
Bad connection of the
pulse signal line.
•
Check the connections of the
controller and driver.
•
Review the specifications
(voltage and width) for input
pulse.
