34.08 DispParam2Sel (select signal / parameter to be displayed in the DCS Control Panel row 2) 
Index pointer to the source of the DCS Control Panel second display row [e.g. 114 equals 
ArmVoltAct (1.14)]. 
Int. Scaling:  1 == 1   Type:  I  Volatile:  N 
34.15 DispParam3Sel (select signal / parameter to be displayed in the DCS Control Panel l row 3) 
Index pointer to the source of the DCS Control Panel third display row [e.g. 116 equals 
ConvCurAct (1.16)]. 
Int. Scaling:  1 == 1   Type:  I  Volatile:  N 
Overview of the PID controller: 
 
40.01 KpPID ( p-part PID controller) 
Proportional gain of the PID controller
. 
 
The controller generates 15 % output with 
KpPID (40.01) = 3, if the input is 5 %. 
Int. Scaling:  100 == 1  Type:  I  Volatile:  N 
40.02 TiPID (i-part PID controller) 
Integral time of the PID controller
. TiPID (40.02) defines the time within the integral part of the controller 
s the same value as the proportional part. 
 
The controller generates 15 % output with
 KpPID (40.01) = 3, if the input is 5 %. On that condition and with 
 = 300 ms follows: 
  the controller generates 30 % output, if the input is constant, after 300 ms are elapsed (15 % from 
proportional part and 15 % from integral part). 
Int. Scaling:  1 == 1 ms  Type:  I  Volatile:  N 
40.03 TdPID (d-part PID controller) 
PID controller derivation time. 
TdPID (40.03) defines the 
time within the PID controller derives the error value. 
The PID controller works as PI controller, if
 TdPID (40.03) is set to zero. 
Int. Scaling:  1 == 1 ms  Type:  I  Volatile:  N 
40.04 TdFiltPID (filter time for d-part PID controller) 
Derivation filter time.
 
Int. Scaling:  1 == 1 ms  Type:  I  Volatile:  N 
40.06 PID Act1 (PID controller actual input value 1 index) 
Index pointer to the source of the PID controller actual input value 1. The format is 
-xxyy, with: - = negate 
xx = group and yy = index [e.g. 101 equals MotSpeedFilt (1.01)]. 
Int. Scaling:  1 == 1   Type:  SI  Volatile:  N
