Technology controller: Speed droop
A parameterizable feedback loop can be connected in parallel to the I and P components of the technology controller (acts on summation
point of setpoint and actual value). This loop can be activated and deactivated by settings in parameter U496 (loop can also be
deactivated by setting U497 = 0).
U496 Source for control bit for speed droop injection
(2496)
0 = binector B0000
*
1 = binector B0001
S00
etc.
(B170)
U497 Speed droop
(2497)
Example:
S00
A 10% speed droop setting causes a 10% reduction in the setpoint at a
FDS
100% controller output ("softening" of closed-loop control).
