0.1...999.9 digit 10 Affects the P-response of the controller
Derivative time
dt
0...9999 s 80 Affects the D-response of the controller.
Within dt = 0, the controller has no D-
response.
For modulating controllers, dt = rt / 4 or
0 must be entered.
Integral action time
rt
0...9999 s 350 Affects the I-response of the controller.
With rt = 0, the controller has no I-
