MICROMASTER 440 Parameter List
236 6SE6400-5BB00-0BP0
P2267 Max. value for PID feedback Min: -200.00
CStat: CUT Datatype: Float Unit: % Def: 100.00
P-Group: TECH Active: Immediately QuickComm.: No Max: 200.00
Sets the upper limit for the value of the feedback signal in [%].
Note:
- P2267 = 100 % corresponds to 4000 hex
- When PID is enabled (P2200 = 1) and the signal rises above this value, the inverter will trip with F0222 .
P2268 Min. value for PID feedback Min: -200.00
CStat: CUT Datatype: Float Unit: % Def: 0.00
P-Group: TECH Active: Immediately QuickComm.: No Max: 200.00
Sets lower limit for value of feedback signal in [%].
Note:
- P2268 = 100 % corresponds to 4000 hex
- When PID is enabled (P2200 = 1) and the signal rises below this value, the inverter will trip with F0221.
P2269 Gain applied to PID feedback Min: 0.00
CStat: CUT Datatype: Float Unit: - Def: 100.00
P-Group: TECH Active: Immediately QuickComm.: No Max: 500.00
Allows the user to scale the PID feedback as a percentage value [%].
A gain of 100.0 % means that feedback signal has not changed from its default value.
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
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
