17. Troubleshooting
Refer to the table below for troubleshooting. When none of the causes in the troubleshooting can be
confirmed, it is presumed that the product is faulty and normal operation can only be recovered by the
replacement of a part.
It is possible that this product may be damaged due to the operating conditions (applications). Please contact
SMC to discuss appropriate measures.
17.1 Operation errors
Problem
Possible
cause
Investigation method and location of
possible cause
Countermeasure
Does not
operate
at all.
Power fault
Is the green LED on the controller ON?
Check the power, voltage and current
supplied to the controller.
External
equipment
failure
Check that the PLC connected to the
controller operates correctly.
Test operation of the controller on its own.
Refer to the Operation Manual and take
appropriate measures.
Incorrect
wiring
Is the wiring connected correctly?
Check if the controller is wired correctly, if
there are no broken wires or short circuits
with reference to the controller operation
manual.
Correct the wiring and confirm that the
input/output of each signal is correct.
Separate the power supply for the CN1
controller and the CN5 I/O signal power
supply.
Alarm
generated
Check if the controller has generated an
alarm? Check the type of alarm.
If applicable, check the type of alarm
referring to this operation manual.
Refer to the Operation Manual and take
appropriate measures.
Lock
release
error
Is the lock releasing sound generated when
the lock switch is turned on and off?
If there is no sound of lock release, the lock
brake may be broken.
→ If the problem persists, please contact
SMC.
Unsuitable
specification
Check if the controller
’s specifications are
appropriate, the power supply is suitable
and the controller is compatible with the
actuator.
If a blank controller is used, check that the
written data is identical with the actuator
used.
Check that the product number of the
actuator used matches with the actuator
which is applicable to the controller before
use.
If a blank controller is used, write the data,
which is identical with the product number of
the actuator used.
Influence of
a magnetic
force
Check if there is equipment which generates
the magnetic force, such as a magnet or
electro-magnetic coil around the actuator.
The equipment, which generates the
magnetic force, should be kept away from the
motor.
For example, keep 40 mm minimum distance
from the cylinder with auto switch.
