9.5.12 Number of counts per Measuring Range -- [CMR]
This scaling parameter shows the number of distinguishable steps over the total measuring
range and corresponds with the scaled measuring range.
For
rotary encoders
the data range (hex) is specified for:
Octet 44
Octet 45
Octet 46
Octet 47

The
linear encoder
KHK53-P always supports a max. range of 16,777,216 steps. This corre-
sponds with a resolution of 2**24 or [01.00.00.00] in hex format.
9.5.13 Serial Number
The encoder serial number is given as an ASCII string with ten (10) characters. If the number is
not used, the string only contains asterisks (*) --- hex code: [2A].
9.6 Manufacturer-Specific Diagnostics (Manufacturer Class)
This part is contained in the Class 2 diagnostics (table 9.5.1 from entry “manufacturer-specific)
as an extension of 4 bytes.
9.6.1 Station Address
Gives the device address number (station or device address number) which is stored in the
EEPROM and must not match with the setting shown for the external DIP switches.
9.6.2 Encoder Status
Displays the encoder status. Bit no. 0-3 corresponds with the parameter value 'Operating
Mode’. The remaining bits are used for internal settings.
The value is different for the individual encoder types and corresponds – with few
exceptions – to diagnostic octet 9 (operating status).
