Investigation method and the
location of possible causes
Countermeasures
Displaced
from the
origin
position
In case of return to origin position on the
pushing or retracting end position, does
the actuator travel to the origin position?
Perform return to origin position several
times to check the origin position.
Check actuator's operation (if foreign matter
is caught in the product etc.).
Inappropriate
parameter
input
Check if the values for the parameter
are appropriate and the program is
correct.
Reconfirm the target position,
positioning time and load mass.
Modify the parameters to appropriate ones
and test the operation.

8. Setting Data input (P.29)
Unsuitable
specification
Check that the Basic Parameter Setup
settings in the controller (product number
and mounting orientation of the Card
Motor) correspond to the product number
and mounting orientation of the Card
Motor that is connected to the controller.
Set the product number and mounting
orientation of the Card Motor to the controller.

12.2 Basic Parameter Setup window (P.51)
Use in a
strong light
source.
Check that the Card Motor is not
exposed to a strong light source such as
direct sunlight.
Install a light shielding plate as a cover.
Displacement
Signal timing
The Card Motor has been commanded to
execute a new relative step data whilst
the table of the Card Motor was still
moving.
A relative positioning has been performed
from a position with remained deviation.
In relative positioning the table moves the set
travel distance from the current table
position.Therefore ensure that the initial table
starting position is where the table is supposed
to be before starting relative positioning.

8.2 Step Data Setup setting method and
movement profiles (P.32)
Incorrect
wiring
Check if the wiring is correct.
Refer to the operation manual of the
controller to check wiring, broken wires
and short-circuits.
Correct wiring and check if the input/output of
each signal is correct.
Separate the power supply for the
CN1controller power supply and the CN5 I/O
signal power supply.

4. External connection (P.17)
→
7.4 Parallel I/O connector wiring
(Example)
(P.28)
Unsuitable
specification
Check that the Basic Parameter Setup
settings in the controller (product number
and mounting orientation of the Card
Motor) correspond to the product number
and mounting orientation of the Card
Motor that is connected to the controller.
Set the product number and mounting
orientation of the Card Motor to the controller.

12.2 Basic Parameter Setup window (P.51)
Doesn't
move to the
correct
position
Signal timing
Check the timing of the signals from the
PLC to the controller.
The DRIVE signal is turned OFF whilst a
step data is being executed.
PLC processing and controller scan delay
times are generated. Ensure an interval of 2
msec or more between input signals, and
maintain the signal state for at least 2 msec.
When the DRIVE signal is turned OFF, the
table of the Card Motor stops on the spot,
and holds the position.
If it is required that the operation is
completed, do not turn OFF the DRIVE signal
until the operation has been completed.
