BEI Sensors MHK5 Absolute Hollow Shaft Encoder - Manual (Page 22)

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 35.
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.
The user only has to take care of this parameter if
the parameters are set “manually” in hex-code.
Octet 39 Bit 1 Type
0 Singleturn
1 Multiturn
5.1.9 Velocity time base
With this parameter the user can choose the time
base for the velocity output (version 2.2). The time
base is specified in bits 4 and 5 of octet 39.
Time base Bit 4 Bit 5
Steps / second 0 0
Steps / 100 ms 1 0
Steps / 10 ms 0 1
RPM (revolutions per minute) 1 1
