Range
POSITIVE LIMIT
405
0.00 to 105.00 %
The upper limit of the PID algorithm.
NEGATIVE LIMIT 406 -105.00 to 0.00 %
The lower limit of the PID algorithm.
O/P SCALER (TRIM)
407
-3.0000 to 3.0000
The ratio that the limited PID output is multiplied by in order to give the final PID Output. Normally this ratio would be between 0 and 1.
INPUT 1 410 -300.00 to 300.00 %
PID setpoint input. This can be either a position/tension feedback or a reference/offset.
INPUT 2
411
-300.00 to 300.00 %
PID feedback input. This can be either a position/tension feedback or a reference/offset
RATIO 1 412 -3.0000 to 3.0000
This multiplies Input 1 by a factor (Ratio 1).
RATIO 2
413
-3.0000 to 3.0000
This multiplies Input 2 by a factor (Ratio 2).
DIVIDER 1 418 -3.0000 to 3.0000
This divides Input 1 by a factor (Divider 1).
DIVIDER 2
414
-3.0000 to 3.0000
This divides Input 2 by a factor (Divider 2).
ENABLE 408 DISABLED / ENABLED
Enables or disables the PID output.
INT. DEFEAT
409
OFF / ON
When ON, the Integral term is disabled. The block transfer function then becomes P+D only.
HI RES PROP GAIN 1259 0.000 to 100.000
Additive, high resolution, proportional term gain. This value is added to PROP GAIN to form the total proportional term gain. Its default value is
0.000 (unused).
