Scaling
P2h: High scaling value
Adjustment range:
-1999
≤ P2h ≤ 9999
When setting P2h, a decimal point position can be defined, which
is then also valid for P2l and PV0. If, with this setting, the value is
below the lower scaling value, the lower scaling value will be set to
the same value as the upper.
P2l: Low scaling value
Adjustment range:
-1999
≤ P2l ≤ P2h
Feed forward control
(Applicable to the
feed forward control structure only)
Kps: Proportional action coefficient gain of the PDT1 element
Adjustment range:
-999.0 ≤ Kps ≤ 999.9
Tds: Derivative action time of the PDT1 element
Adjustment range:
-1999
≤ Tds ≤ - 9999 (in sec.)
Ts: Time constant of the PDT1 element
Adjustment range:
0
≤ Ts ≤ 9999 (in sec.)
PV0: Operating point:
Adjustment range:
P2l ≤ PV0 ≤ P2h
Filter 2
Fg2: Limiting frequency (-3 dB) of the filter at input 2
Adjustment range:
0.1
≤ Fg2 ≤ 20.0 (in Hz)
0.1 Hz: strong damping (time constant = 1.6 sec)
20 Hz: weak damping (time constant = 0.01 sec)
Sub-menu of the main menu option Controller 1
(Only when using the cascade control structure)
RPar 1
Controller parameter of the main controller when using cascade control
Kp1: Proportional action coefficient gain
Adjustment range:
0.001
≤ Kp1 ≤ 999.9
Tr: Reset time
Adjustment range:
0.4
≤ Tr ≤ 9999 (in sec.)
With the setting 9999, the I-portion of the controller is switched off
(P or PD controller)
