In accordance with
actuator
This is the parameter to set the velocity in pressing operation.
If a change to the setting is required, make sure to have the setting below the maximum
pressing velocity of the actuator. Setting it fast may disable to obtain the specified pressing
force. Also when setting at a low velocity, take 5mm/s as the minimum.

Judging completion of pressing operation
Monitoring the torque (current limit) set in “Pressing Force” in the operation condition table
in %, it turns ON the pressing complete signal PE* when the load current during pressing
operation comes to the following condition. PE* turns ON once the condition is satisfied even
if the work is not stopped.
