The actuator
does not move
correctly.
Incorrect
wiring
Is the wiring 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.

5. External Connections (P. 22 )
⇒
10.1 Memory allocation (P. 32 )
Unsuitable
specification
Check if the controller’s
specifications are appropriate, the
power supply is suitable and the
controller is compatible with the
actuator.
Take appropriate measures according to
this manual.
⇒
3. Specifications (P. 12 )
Signal
timing Check the timing of the signal
from the PLC to the controller.
Set the interval time between signals to
more than twice the communication
cycle time, when the signals are to be
continuously input, because PLC
processing delays and controller
scanning delays can occur.
⇒
12.4 Controller input signal
response time (P. 52 )
Data not
stored
correctly
Check whether data (step data,
parameter) is written correctly.
Do not turn OFF the controller
input power or remove the
cable while data is being written
(green light flashing).
Input correct data (step data, parameter)
again and confirm operation.

3.2 Parts Description (P. 13 )
⇒
11. Settings and Data Entry (P. 44 )
Speed not
achieved
Incorrect
parameters
Check that the parameter
values are correct.
Review the maximum speed
and the maximum acceleration
of the actuator.
Modify the values of the parameters
and test the operation.
⇒
11. Settings and Data Entry (P. 44 )
Operation
pattern is
not suitable.
Check if a trapezoidal
acceleration/deceleration is
programmed for the actuator
operation. In case of such
operation, the actuator may
start slowing down before it
reaches the maximum speed.
Modify the setting to make the moving
distance longer or the acceleration
larger.
⇒
11. Settings and Data Entry (P. 44 )
Unsuitable
specification
Check if the controller’s
specifications are appropriate,
the power supply is suitable and
the controller is compatible with
the actuator.
Take appropriate measures according to
this manual.
⇒
3. Specifications (P. 12 )
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 of CN1 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 "inrush-current control"
type.
If necessary, replace the power supply.
