WARNING
Every time you change the value in this object then you are required to set a
new preset value (see the
6003 Preset value
object) and finally save the new
parameters (see the
Store parameters
function).
EXAMPLE
We install the HM58
16
/
16384
PL multiturn encoder.
Its physical resolution is as follows (see the order code):
 Hardware counts per revolution:
6501 Singleturn resolution
= 65,536
(2 16 )
 Hardware number of revolutions:
6502 Number of revolutions
= 16,384
(2 14 )

Total hardware resolution:
6501 Singleturn resolution
*
6502
Number of revolutions
= 1,073,741,824 (2
30
)
In the specific installation 2,048 counts/rev.

1,024 turns are required:
 Enable the scaling function:
6000 Operating parameters
, bit 2
Scaling
function = “1”

Counts per revolution:
6001 Measuring units per revolution
= 2,048
(0000 0800h)
 Total resolution:
6002 Total measuring range in measuring
units
= 2048

1024 = 2,097,152 (0020 0000h)
NOTE
We suggest setting values which are power of 2 (2
n
: 2, 4, …, 2048, 4096, 8192,…)
to be set in the
6001 Measuring units per revolution
and
6002 Total
measuring range in measuring units
objects to avoid counting errors.
WARNING
If
6001 Measuring units per revolution
and/or
6002 Total measuring
range in measuring units values change, the 6003 Preset value must be
updated in accordance with the new resolution. A new preset operation is also
required.
