MICROMASTER 420 Parameter List

82 6SE6400-5BA00-0BP0

r1912 Identified stator resistance Min: -

Datatype: Float Unit: Ohm Def: -

P-Group: MOTOR Max: -

Displays measured stator resistance value (line-to-line) in [Ohms]

Note:

This value is measured using P1910 = 1 or 2 , i.e., identification of all parameters with/without change.

P2000 Reference frequency Min: 1.00

CStat: CT Datatype: Float Unit: Hz Def: 50.00

P-Group: COMM Active: first confirm QuickComm. No Max: 650.00

Full-scale frequency setting used by serial link (corresponds to 4000H), analog I/O and P/D controller.

Example:

If a BICO connection is made between two parameters or alternatively using P0719 or P1000, the 'unit' of

the parameters (standardized (Hex) or physical (i.e. Hz) values) may differ. MICROMASTER implicitly

makes an automatic conversion to the target value.

Notice:

Reference variables are intended as an aid to presenting setpoint and actual value signals in a uniform

manner. This also applies to fixed settings entered as a precentage. A value of 100 % correspondes to a

process data value of 4000H, or 4000 0000H in the case of double values.

In this respect, the following parameters are available:

P2001 Reference voltage Min: 10

CStat: CT Datatype: U16 Unit: V Def: 1000

P-Group: COMM Active: first confirm QuickComm. No Max: 2000

Full-scale output voltage (i.e. 100 % ) used over serial link (corresponds to 4000H).

Example:

P2001 = 230 specifies that 4000H received via USS denotes 230 V.

If a BICO connection is made between two parameters, the 'unit' of the parameters (standardized (Hex) or

physical (i.e. V) values) may differ. MICROMASTER implicitly makes an automatic conversion to the target

value.
