Range

6501-00 Hardware counts per

revolution

The value in the  

6001-00 Units per revolution

  object must be less than or

equal to the value in the  

6501-00 Hardware counts per revolution

  object.

The total custom resolution in the  

6002-00 Total Measuring Range

  object

must be less than or equal to the maximum physical value (

6501-00 Hardware

counts per revolution

 * 

6502-00 Hardware number of turns

).

Default = 0

To know whether the 

Scaling function

 is currently enabled, you can read the

bit 2 

Scaling function

 of the 

6500-00 Operating status

 object, see on page

77.

WARNING

When you enable the scaling function (bit 2 

Scaling function

 = 1), please enter

scaled values next to the 

6001-00 Units per revolution

 and 

6002-00 Total

Measuring Range

 objects that are consistent with the physical values. In the

case   of   inconsistent   values,   the   system   will   warn   about   the   wrong
parametrization and fault condition by means of the dedicated objects and
visually by means of the diagnostic LEDs.

WARNING

Every time you enable the scaling function and/or change the scaled values (see
the 

6001-00 Units per revolution

  and  

6002-00 Total Measuring Range

objects),  then you are required to set a new preset value (see the  

6003-00

Preset value

 object).

6001-00 Units per revolution

[Unsigned32, rw]

WARNING

This   object   is   active   only   if   the  bit   2  

Scaling   function

  in  the  

6000-00

Operating parameters

  object is set to ”=1”; otherwise it is ignored and the

system uses the physical values (

6501-00 Hardware counts per revolution

and  

6502-00   Hardware   number   of   turns

)   to   calculate   the   position

information.

This   object   sets   a   custom   number   of   distinguishable   steps   per   revolution
(custom singleturn resolution).
