7. Operation of MEC Related Controllers
191
[Auto motor power (Auto servo) OFF]
The motor power (servo) will turn off automatically upon elapse of a specified period after completion of
positioning. When the next positioning command is issued, the motor power (servo) turns on automatically
and positioning is performed. Since no holding current flows while the motor is at standstill, power
consumption can be reduced.
[Statuses of position detection output signals when the push function is not used]
Even when the motor power (servo) is turned off, as long as the actuator is positioned within the positioning
band (parameter No. 1) the start point detection signal (LS0), end point detection signal (LS1) or
intermediate point detection signal (LS2) will turn ON according to the applicable position, just like when a
sensor is used. Accordingly, the position detection signal that has turned ON will remain ON after
completion of positioning unless the actuator moves.
[Status of position complete signals when the push function is used]
In push-motion operation, the motor power (servo) does not turn off automatically while the actuator is
pushing the work part.
If the actuator has missed the work part, the motor power (servo) turns off automatically.
Once the motor power (servo) turns off, a position complete status is lost. Accordingly, the push complete
signal 0 (PE0), push complete signal 1 (PE1) and push complete signal 2 (PE2) will all turn OFF regardless
of the stop position.
Caution: No holding torque is applied in the auto servo OFF mode. Since the actuator will move in
this condition if an external force is applied, pay due attention to contact and safety when
setting any operation involving auto motor power (servo) OFF.
