4. Description of Operating Functions
4.4.4 Push & Hold Operation
The actuator can continue to hold work in position while the rod end is pushing it, like an air cylinder.
Therefore, it can be used in the operation of work clamping or press fit process.
(1) Basic operation
After moving to the target position set as shown below, the actuator will move at the set push speed and push
work by the push amount set as the maximum.
When a push force reaches a certain value in the middle of push & hold operation, the position complete signal

y- Concept of push direction
When work is pushed in the direction which increases the coordinate value from the start position toward the
target position as shown above, the push direction will be positive (+). On the other hand, when work is pushed in
the direction which decreases the coordinate value, the push direction will be negative (-). If the positioning band
is entered with an incorrect sign, the position will deviate by twice the positioning band, as shown below.
Therefore, exercise sufficient caution.
