5.1 Parameters
Manufacturer specific parameters are described in greater detail below. For a
description of parameters based on the encoder profile (that are also supported), see
section 4.
5.1.1 Activation of manufacturer specific parameters
• The manufacturer specific parameter byte 26 is activated with Bit 6 in Octet 9.
• Manufacturer specific Octets 27 ... 39 are further activated in Octet 26.
If Encoder class P+F 2.1 or P+F 2.2 is selected, this happens automatically. These
bits only need to be considered if parameters are assigned "manually" in
hexadecimal.
5.1.2 Desired measurement steps
The parameter "Desired measurement steps" is used to program the device so that
any number of measurement steps can be implemented in reference to one
revolution, the entire measurement range or any given partial measurement range.
What the measurement steps refer to is specified with the parameter "Resolution
reference" (see section 5.1.3). If "per revolution" is selected here as the reference for
the desired measurement steps, the measurement range can be adjusted with the
parameter "Overall resolution". The rules listed in section 4.1.6 must be taken into
consideration for this.

For many projecting tools, the value must be divided up into high word
and low word; for more information see section 7.4, page 34.
