Problems
Possible
causes
Investigation method
Countermeasures
Does not
operate at
all.
Incorrect
wiring
Check that the wiring is 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.
Prepare a separate power supply for the
main control, motor drive and motor control,
and input/ output signals.

Alarm
generated
Check if the controller has generated an
alarm? Check the type of alarm, referring
to this Operation Manual.
Refer to this manual and take appropriate
measures.
-> 13. Alarm detection
Lock release
error
When the unlock switch is turned ON or
OFF there is an unlocking sound made.
If there is no sound of lock release, the
lock brake may be broken.
-> If the problem persists, please contact
SMC.
Unsuitable
specification
Check that the controller parameter
settings for the product model and power
supply specification are appropriate for the
actuator connected.
Check that the actuator product number
matches the controller parameters.
Check that the power supply specification
is correct,

Check if the controller has generated an
alarm? Check the type of alarm, referring
to this manual.

Check that the wiring is connected
correctly?
Refer to this manual to confirm wiring, and
check for broken wires and short-circuits.

control, and input/ output signals.

Electrical
noise
Connect to Ground correctly.
Avoid bundling the cables.
Refer to this manual and take appropriate
measures.
-> 4.4 Mounting
Incorrect
parameters
Check that the parameter values are
correct.
Check that the appropriate parameters are
used for the actuators connected.
Modify the values of the parameters and test
the operation.
-> 9. Settings Data Entry
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 terminal in the
motor control power 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
an “inrush-current protection”
type.
-> 4. Product Specifications
Failure of
pushing
operation.
Check that the INP turns on during a
pushing operation.
(If completion of the pushing operation is
detected by the INP, the PLC cannot
confirm the completion).
Check the INP output signal before the
energy saving mode is turned on.
