5.8 Units
For the conversion of different units, the DSP 402 profile provides the so-called Factor
group. From this group, encoTRive implements the following partial quantity:
5.8.1 Object 0x608F: Position encoder resolution
This parameter defines the ratio between position increments and motor revolutions:
srevolution Motor
increments Position
resolution encoder Position
Formula 1: Position encoder resolution
The fraction counter is defined in subindex 1, the denominator in subindex 2.
The default value is
srevolution Motor
increments Position
4096

4096
resolution encoder Position
Default
Formula 2: Default value, position encoder resolution
5.8.2 Object 0x6090: Speed encoder resolution
This parameter defines the ratio between speed increments per second and motor
revolutions per second:
sec
srevolution Motor
sec
increments Speed
resolution encoder Speed
Formula 3: Speed encoder resolution
The fraction counter is defined by subindex 1, the denominator by subindex 2.
The default value is
srevolution Motor
increments Speed
