5. Operation Using I/O Signals

z Normal Operating Procedure

The operating procedure in a normal condition is explained below.
[1] Confirm that the slider or rod is not contacting a mechanical end or that the work is not contacting any peripheral

equipment.

[2] Cancel the emergency stop or connect the motor drive power.
[3] Supply the 24-VDC I/O power.
[4] Supply the 24-VDC controller power.
[5] Input a servo-on signal from the PLC (if the servo-on input is enabled).
[6] First, input a rear end move command signal from the PLC (to cause the actuator to stand by at the rear end).
[7] Start automatic operation.

(Note 1) : Excited-pole detection time = 0.2 to 12 sec

Normally the detection of excited pole completes in approx. 0.2 sec, although the exact time varies from one
actuator to another due to individual differences and also depending on the load condition. If the detection of
excited pole has failed, the excited-pole detection operation will be continued for up to 12 sec.
