P2261
PID setpoint filter timeconstant
Min: 0.00
CStat:
CUT
Datatype: Float Unit:
s
Def:
0.00
P-Group: TECH
Active: Immediately
QuickComm.: No
Max: 60.00
Sets a time constant for smoothing the PID setpoint.
Note:
0 = no smoothing
r2262
CO: Filtered PID setp. after RFG
Min: -
Datatype: Float Unit:
%
Def:
-
P-Group: TECH
Max: -
Displays the filtered PID setpoint after the PID ramp-function generator (PID_HLG) as percentage.
Parameter r2262 is obtained from the filtered parameter r2260 that is filtered using the PT1 filter with time
constant P2261.
Note:
r2262 = 100 % corresponds to 4000 hex

Def:
0
P-Group: TECH
Active: Immediately
QuickComm.: No
Max: 1
Sets the PID controller type.
Possible Settings:
0
D component on feedback signal
1
D component on error signal
