resolution of the encoder (type label) is used.
For our example this would be (with a
standard encoder, 12 Bit resolution):
4096 steps/revolution x 3 revolutions = 12288
steps
Enter this value (12288) as „physical impulses“
and set the „desired measuring units“ to 400. Now the encoder increases the position value
by 400 steps on a measuring range of 12288
physical steps (3 revolutions).
Note: With many software tools it is necessary
to divide the value into high and low word,
refer to page 34.
5.1.8 Encoder type
The encoder type (Singleturn or Multiturn) is
specified in bit 1 octet 39. Generally this bit is
set automatically if the encoder version is
selected. Not used. The encoder type is set
automatically with using parameters resolution and total range, if total range is equal to
resolution, the encoder type is singleturn..

5.1.9 Velocity time base
With this parameter the user can choose the
time base for the velocity output (version BEI
IDEACOD 2.2). The time base is specified in bits
4 and 5 of octet 39.
