Code sequence
This is intended to set whether the count increases (count up information) when
you rewind the wire or when you pull the wire out.
Setting 0 (bit 0
Code sequence
= 0) causes the position value to increase when
you rewind the wire; on the contrary, setting 1 (bit 0
Code sequence
= 1)
causes the position value to increase when you pull the wire out.
Default = 1
To know whether the Code sequence is currently set to “Count up rewinding
the wire” or “Count up pulling the wire out”, you can read the bit 0
Code
sequence
of the
6500-00 Operating status
object, see on page 77.
WARNING
Every time you change the
Code sequence
, then you are required to set a new
preset value (see the
6003-00 Preset value
object).
Scaling function
This is meant to enable / disable the scaling parameters
6001-00 Units per
revolution
and
6002-00 Total Measuring Range
.
When the scaling function is disabled (bit 2
Scaling function
= 0), the encoder
uses its own physical resolution (i.e. hardware counts per revolution and number
of hardware revolutions, see the encoder identification label and the
6501-00
Hardware counts per revolution
and
6502-00 Hardware number of turns
objects; see also on page 21) to arrange the absolute position information.
On the contrary, when the scaling function is enabled (bit 2
Scaling function =
1), the encoder uses the custom resolution set next to the 6001-00 Units per
revolution
and
6002-00 Total Measuring Range
objects according to the
following relation:
