BEI Sensors MHK5 Absolute Hollow Shaft Encoder - Manual (Page 18)

5.1 Parameter
In the following the manufacturer specific
parameters are described in detail. The parameters according to the Profile for Encoders
are supported too, description: see chapter 4.
5.1.1 Activate manufacturer-specific parameters
The manufacturer-specific parameter byte 26 is
activated with bit 6 in octet 9.
Bit 7 in octet 26 activates further parameter bytes
(27-39).
Usually this happens automatically if the encoder
versions 2.1 or 2.2 are selected. It is only
important for the user to observe this if the
parameters are entered “manually” (directly using
hex-code).

5.1.2 Desired measuring units
The parameter „desired measuring units“ is used to
program any required number of steps over 1 revolution, over the whole measuring range or over
a part of the measuring range.
The reference for the desired measuring units is
specified with the parameter „Desired measuring
units reference“ (cp. 5.1.3). If “per revolution” is
selected the measuring range can be adapted with
the parameter “total measuring range”. Please
observe the rules in section 4.1.6.
Note: With many software tools it is necessary to
divide the value into high and low word, refer to
page 35.
