Setback time (integral component) for feed rate
controller
Setback time TN is the time during which the I
component causes the same change in control
magnitude as the P component.
Exceptions:
1. KP = 0 : I controller
TN is the reciprocal of integration
constant KI, i.e. big value = slow
controller.
KI = 1/TN in %/(mA/s)
2. TN = 0 : P controller
I component is removed.
3. KP=TN= 0 : Controller output = elevation
