(11) Stop Mode: - It defines the power saving method on standby after completion of
positioning to the target position set in the “Position” field of the position
number.
0: Invalid power saving method * The default setting is 0 (invalid).
1: Auto servo OFF method. Delay time defined with the parameter No. 36
2: Auto servo OFF method. Delay time defined with the parameter No. 37
3: Auto servo OFF method. Delay time defined with the parameter No. 38
4: Full servo control method
Full servo control method
The holding current can be reduced by servo-controlling the pulse motor.
The degree of reduction varies depending on the actuator model, load condition, etc.,
but the holding current decreases approximately by a factor of 2 to 4.
No displacement occurs since this method maintains the servo ON status.
The actual holding current can be checked on the monitoring screen of PC-compatible
software.
Auto servo OFF method
When a given length of time has elapsed after completion of positioning, the servo OFF
status is automatically entered.
(Since the holding current does not flow, the power consumption can be saved by the
same amount.)
When a movement command is subsequently given fr om PLC, the status returns to
the servo ON and the actuator starts to move.
