7. Operation in the “8 Points” and “16 Points” Modes <Practical
Operation>
7.1 How to Start
(1) Confirm that the connector end (CN1) of the extension cable is firmly plugged into the connector on the actuator
cable.
(2) Connect the PLC and the parallel I/O.
(3) If the actuator has a brake, set the brake release switch to OFF.
(4) Supply 24 VDC to the control power supply.
Cut off the motor-drive power supply (actuate an emergency stop) beforehand.
(5) Confirm that the slider or rod is not contacting the mechanical end. If the slider or rod is contacting the
mechanical end, or when the slider or rod is positioned between the mechanical end and home, move the
slider/rod away from the home position toward the direction opposite to the mechanical end.
If the actuator is equipped with a brake, move the slider/rod after releasing the brake by turning on the brake
release switch. At this time, pay attention to prevent the load from falling by its dead weight and protect your
hand, robot, and the work part from injuries/damages.
If the screw lead is too short and the actuator cannot be moved by hand, change the setting of parameter No. 28,
“Direction of excited-phase signal detection” to the direction opposite to the mechanical end.
Warning: Turning on the servo while the slider or rod is still contacting the mechanical end may disable
accurate detection of the excited phase, resulting in malfunction or excitation detection error.
(6) Connect a PC or teaching pendant and set the minimum parameters required.
x If the pause input is not used, set parameter No. 15 “Pause input disable selection” to “1.”
x To select “16 points,” set parameter No. 25 “PIO pattern selection” to “2” or “3.” (This setting is required.)
For details, refer to 8, “Parameter Settings.”
(7) Cancel the emergency stop so that the motor drive power will be supplied.
 The controller servo will be turned on and a green LED lamp will illuminate on the motor cover.
(8) If the pause signal (*STP) is enabled, turn the signal ON from the PLC.
 The position complete output (PEND) will turn ON.
 A red LED lamp indicates an alarm. Remove the cause of the alarm.
For details, refer to 9, “Troubleshooting.”
(9) Perform home return.
