PI control
A generic PI controller is available in parameter group 87 Master position for sync
correction. The controller is enabled by parameter 87.32, and configured in group
85 PI control.
The value of the controller output is defined in percent (1 = 100%) to be added
based on follower speed. For example, a value of 0 will not change the axis speed
while a value of 1 will increase the speed by 100%. -1 will stop the axis and -2 invert
the direction.
