setting is not allowed. When this happens, the encoder falls into an error
signalling the faulty condition through the diagnostic LEDs (see on page 33).
WARNING
When you enable the scaling function (
enter scaled values next to the
6001-00 Programmable pulse per revolution
6002-00 Programmable total measuring range
consistent with the physical values. In the case of inconsistent values, the
system does not go online and visually warns about the wrong parametrization
and fault condition by means of the diagnostic LEDS.
WARNING
Every time you change the value in this object then you are required to set a
new preset value (see the
object).
EXAMPLE
We connect the HM58
16
/
16384
rotary encoder.
The physical resolution is as follows:
Hardware counts per revolution:
(2
16
)
Hardware number of turns:
6502-00 Number of distinguishable
= 16,384 (2

)
Total hardware resolution:
*
6502-00 Number of distinguishable revolutions
= 1,073,741,824 (2

)
In the specific installation 2,048 counts/rev.
1,024 turns are required:
1. Enable the scaling function:
, bit 2
= “1”
2. Counts per revolution:
6001-00 Programmable pulse per revolution
= 2,048 (0000 0800h)
3. Total resolution:
6002-00 Programmable total measuring range
= 2048
1024 = 2,097,152 (0020 0000h)
NOTE
We suggest setting values which are power of 2 (2
