with actuator
This is the parameter to set the speed in pressing operation.
The setting is done considering the actuator type when the product is delivered. [Refer to List
of Connectable Actuator Specifications in the last pages.]
If a change to the setting is required, make sure to have the setting below the maximum
pressing speed of the actuator. Setting it fast may disable to obtain the specified pressing
force. Also when setting at a low speed, take 5mm/s as the minimum.

Judging completion of pressing operation
This function monitors the torque (current limit) set in % in “Pressing” or “Pressing Force” in
the position table, and turns the pressing complete signal PEND ON when the load current
during a pressing operation meets the condition shown in the diagram below. PEND is turned
ON at satisfaction of the condition if the work is not stopped.
