Push & Hold Mode

Example of use in operation)

The actuator is caused to move back and forth in the push & hold mode and positioning
mode. The position 280 mm from the home is set as position 1, and the position 40 mm
from the home is set as position 2.
Movement to position 1 is performed in the push & hold mode (the actuator is caused to
contact the load and push it in the counter-motor direction). The maximum push amount
at position 1 is set as 15 mm, and the current-limiting value during the push & hold
operation by the servo motor is set as 50%. Movement to position 2 is performed in the
positioning mode. The travel speed to position 1 is set as 200 mm/sec, and that to
position 2 is set as 100 mm/sec.
