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:

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))

Square (x*x)

Cube (x*x*x)

P2271

PID transducer type

Min: 0

CStat:

CUT

Datatype: U16 Unit:

Def:

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

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
