(5) Set parameters
 Before the 24-V I/O power supply is connected, PIO power monitor can be disabled temporarily by changing
the applicable parameter setting.
Parameter No. 74, “PIO power monitor”: 0 (Enable)
 1 (Disable)
Note) After the 24-V I/O power supply has been connected, be sure to reset parameter No. 74 to “0” to
enable PIO power monitor.
 If the host PLC or other host controller is not yet wired and the servo-on signal cannot be input, the servo-on
input can be disabled temporarily by changing the applicable parameter setting.
Parameter No. 21, “Servo-on input”: 0 (Enable)
 1 (Disable)
Note) After the host PLC, etc., has been wired, be sure to reset parameter No. 21 to “0” to enable the
servo-on input.
Change the safety speed, if necessary.
The factory-set safety speed is “100 mm/sec.” (If the maximum speed is less than 100 mm/sec, the safety speed
conforms to the maximum speed.)
 Select a desired PIO pattern using the applicable parameter.
Parameter No. 25, “PIO pattern selection”: 0 to 5
When a parameter has been changed, the new setting will become effective once the power is reconnected or
software is reset.
(6) Check the servo-on status
When the servo turns on, the SV LED indicator will illuminate in green. (In the MANU teaching mode, the servo
will not turn on even when the servo-on signal is input after the AC power has been turned on.)
If the servo-on input is disabled by the parameter and the controller is in the AUTO mode, the servo will turn on
automatically after the controller has started.
(7) Operate with the PC or teaching pendant
While the servo is on, perform the operation check specified below. For details on the operating method, refer to
the operation manual for your PC software or teaching pendant.
[1] Use the PC or teaching pendant to set a target position in the “Position” field of the position table.
[2] Perform home return.
[3] Move the actuator to the specified position.
(8) Check the actuation of the emergency stop circuit
While the actuator is operating, press the emergency stop button to confirm that an emergency stop will be
actuated.
Caution: When the teaching pendant is disconnected, an emergency stop is actuated momentarily. The
emergency stop will be cancelled immediately thereafter, but the actuator and other equipment that
are operating when the teaching pendant is disconnected will stop.
Therefore, do not disconnect the teaching pendant when an actuator or any other equipment is
operating.
Also pay attention to the design of the emergency stop circuit that includes the emergency stop
switch on the teaching pendant.
