APA
Pressure loop gain
Set the proportional gain of the pressure loop. When "0" is set, the pressure command will be
0.
PT02
AIA
Pressure integral compensation
Set the integral time constant of the pressure loop.
PT03
ADA
Pressure incomplete integral coefficient
Set the incomplete integral factor of the pressure loop.
When "10000" is set, the proportional integral control will be set.
When "0" is set, the proportional control will be set.

Name and function
Explanation
For manufacturer setting
Selection of pressure increasing direction for positioning address
Select a pressure increasing direction for the positioning address.
0: Pressure increases as the positioning address decreases
1: Pressure increases as the positioning address increases
For the pressure control mode, the servo motor rotation direction
and the pressure increasing direction are as follows with a
combination of "Rotation direction selection" in [Pr. PT14].

This is available with servo amplifiers with software version B7 or
later.
In addition, a controller compatible with this function is required.
Forward/reverse-side stop function
Enable/disable the forward/reverse-side stop function.

To use the forward/reverse-side stop function, a controller
compatible with this function is required.
When using the Motion controller of
R64MTCPU/R32MTCPU/R16MTCPU, set the forward/reverse-side
stop function to "_ 1 _ _" in [Pr. PT12].
For the mode in which the pressure control axis keeps reversing
with an error of the pressure sensor (load cell) during the pressure
control, set software stroke limit with the servo system controller.
For details, refer to the manuals for servo system controllers.
