EM58 – HS58 - HM58 MODBUS TCP/IP
Resolution [103-104]
registers in compliance with the
following relation:
Transmitted position =
Counts per revolution [101-102]
*
Real position
≤
Total Resolution [103-104]
Singleturn resolution [113-114]
NOTE
To know whether the
Scaling function
is currently enabled,
you can read the bit 0
Scaling function
of the
Status
word [5-6] input registers, see on page 69.
WARNING
Every time you enable/disable the scaling function and/or
change the scaling values (see the
Counts per revolution
[101-102]
and
Total Resolution [103-104]
registers),
then you are required to set a new preset value (see the
Preset value [105-106]
registers) and finally save the new
parameters (see the
Save parameters
function).
Code sequence
bit 1 It defines whether the position value output by the encoder
increases (count up information) when the encoder shaft
rotates clockwise (0 = CW) or counter-clockwise (1 = CCW).
If the bit 1
Code sequence
= 0, the absolute position value
increases
when the encoder shaft rotates
clockwise
; on
the contrary, if the bit 1
Code sequence
= 1, the absolute
position value
increases
when the encoder shaft rotates
counter-clockwise . CW and CCW rotations are viewed
from the shaft end.
WARNING
Changing this value causes also the position calculated by
the controller to be necessarily affected. Therefore it is
mandatory to execute a new preset (see the
Preset value
[105-106]
registers) and save the parameters after setting
this item.
NOTE
To know whether the
Code sequence
is currently enabled,
you can read the bit 1
Code sequence
of the
Status word
[5-6]
input registers, see on page 69.
