Push & Hold Mode
First, cause the position complete signal to turn ON by referring to 7.1, “How to Start.”
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 stepper 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.
