P2270 PID feedback function selector
Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: TECH Active: Immediately QuickComm. No Max: 3
Applies mathematical functions to the PID feedback signal, allowing multiplication of the result by P2269
(gain applied to PID feedback).
Possible Settings:
0 Disabled
1 Square root (root(x))
2 Square (x*x)
3 Cube (x*x*x)
P2271 PID transducer type Min: 0
CStat: CUT Datatype: U16 Unit: - Def: 0
P-Group: TECH Active: Immediately QuickComm. No Max: 1
Allows the user to select the transducer type for the PID feedback signal.
Possible Settings:
0 Disabled
1 Inversion of PID feedback signal
Value:
P2271 = 0 : [default]
If the feedback signal is less than the PID setpoint, the PID controller will increase motor speed to correct
this.
P2271 = 1 :
If the feedback signal is greater than the PID setpoint, the PID controller will reduce motor speed to correct
this.
Notice:
It is essential that you select the correct tranducer type.
If you are unsure whether 0 or 1 is applicable, you can determine the correct type as follows:
1. Disable the PID function (P2200 = 0).
2. Increase the motor frequency while measuring the feedback signal.
3. If the feedback signal increases with an increase in motor frequency, the PID transducer type should be
0.
4. If the feedback signal decreases with an increase in motor frequency the PID transducer type should be
set to 1.
r2272 CO: PID scaled feedback Min: -
Datatype: Float Unit: % Def: -
P-Group: TECH Max: -
Displays PID scaled feedback signal in [%].
Note:
r2272 = 100 % corresponds to 4000 hex
r2273 CO: PID error Min: -
Datatype: Float Unit: % Def: -
P-Group: TECH Max: -
Displays PID error (difference) signal between setpoint and feedback signals in [%].
Note:
r2273 = 100 % corresponds to 4000 hex
