As you can see, the encoder is required to carry out more than 93,000
revolutions, this cannot be as the hardware number of revolutions is, as stated,
4,096 (see the
6502-00 Number of hardware distinguishable revolutions
object). When this happens, the encoder falls into an error signalling the faulty
condition through the diagnostic LEDs (see on page 34).
WARNING
Every time you enable the scaling function (bit 2
in the
object) and/or change the value in the scaled
values (
6001-00 Measuring units per revolution
objects), then you are required to set a new preset value (see
object) and finally save the new parameters (see the
object).
NOTE
Please refer to the “7 - Setting-up” section on page 79 for an example of how
the
6001-00 Measuring units per revolution
object is to be set.

WARNING
This object is active only if the bit 2
object is set to ”=1”; otherwise it is ignored and the
system uses the physical values (
6501-00 Physical singleturn resolution
6502-00 Number of hardware distinguishable revolutions
) to calculate the
position information.
This object sets a custom number of distinguishable steps over the total
measuring range. The total resolution of the encoder results from the product of
6001-00 Measuring units per revolution
Number of
revolutions

Allowed values are equal to or less than the
