- Cascade Controller with 4 Servo Controllers
Tag Entry Displayed value or function, required input
DEADB % Input of dead band in relation to measuring range (0 - 100 % sat)
Cascade [Controller] Display of the selected servo controller with its parameters
Minimum % Input of minimum output limit, considering the minimum setpoint
for servo controller (0 - 100 % = measuring range process value)
Maximum % Input of maximum output limit, i.e. the maximum setpoint for servo
controller (0 - 100 % = measuring range process value)
XP % Input of proportional range for servo controller [PARAM] in relation
to measuring range
TI sec Input of reset time ifor servo controller [PARAM]
TD sec Input of rate time for servo controller [PARAM]
Hysteresis m:s Delay time for switching over to cascade
Mode off / auto Mode of servo controller after switching off the pO
