Instance Attribute 24 - Velocity Value
This instance attribute contains the current velocity value of the encoder.
Instance Attribute 25 - Velocity Format
This instance attribute contains the format in which the current velocity value of the encoder is displayed.
The following two values are possible:
- 0x1F05 (counts per millisecond, CPMS)
- 0x1F0F (revolution per minute, rpm)
The device supports counts per millisecond (0x1F05) with a predefined factor (per 10 milliseconds, 100
milliseconds or 1000 milliseconds). The factor is adjusted via attribute 26.
Instance Attribute 26 - Velocity Resolution
This instance attribute contains the factor for the velocity format (attribute 25). The factor is called “Supported
resolutions” in the following table.
Unit
Supported resolutions
0x1F05 (counts per ms)
10, 100, 1000
0x1F0F (turns per minute)
1
Instance Attribute 42 - Physical Resolution Span
This instance attribute contains the physical resolution of the encoder. It can be read out in the form of
scanning steps per revolution. The value can also be interpreted as number of distinguishable steps per one
complete span. For rotary devices a span equals one revolution.
Possible values are:
8192 = 0x2000 (for "MT16ST13" device variant)
16384 = 0x4000 (for "MT16ST14" device variant)
262144 = 0x40000 (for "MT13ST18" device variant)
