The electric
actuator does
not move
correctly.
Inappropriate
specifications
Check that the combination of
the electric actuator and
controller is correct?
If the blank controller is used,
check that the written data is
identical with the actuator used.
Check if the product number of the
used electric actuator matches with the
electric actuator which is applicable to
the controller.

3. Product Specifications
If the 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.
Signal timing
Check the timing of the signal
from the PLC to the controller.
Both PLC processing delay and
controller scan delay are generated.
Ensure that 15 ms or more should be
maintained between signals.

Data writing
failure
Is the data (step data or
parameters) written correctly?
One of the following actions occurred
during data writing (while the power
supply LED (green) was on).
・
Turn off the controller input power
supply
・
Disconnected/ connected cables.
Input correct data (step data,
parameter) again and confirm
operation.

Insufficient
speed
Inappropriate
basic
parameters
Check that the parameter values
are correct.
Check the max. speed and
acceleration speed of the electric
actuator and be sure to input the
correct parameters.

7. Setting Data Entry
Inappropriate
step data
Is the operation pattern
trapezoidal?
In case of such operation, the electric
actuator may start slowing down before
it reaches the maximum speed. Modify
the setting to make the moving distance
longer or the acceleration larger.

For example, keep 40 mm minimum
distance from the cylinder with auto
switch.
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.
