Judging completion of pressing operation
(1) For Standard type (PIO pattern 0 to 2)
The operation monitors the torque (current limit value) in percent in “Pressing” of the position
table and turns pressing complete signal PEND ON when the load current satisfies the
condition shown below during pressing. PEND is turned ON at satisfaction of the condition if
the work is not stopped.

In accordance
with actuator
The servo gain is also called position loop gain or position control system proportion gain.
The parameter defines the response when a position control loop is used. Increasing the set
value improves the tracking performance with respect to the position command. However,
increasing the parameter value excessively increases the changes of overshooting.
When the set value is too low, the follow-up ability to the position command is degraded and it
takes longer time to complete the positioning.
For a system of low mechanical rigidity or low natural frequency (every object has its own
natural frequency), setting a large servo gain number may generate mechanical resonance,
which then cause not only vibrations and/or noises but also overload error to occur.
