Brushless motor with sine/cosine encoder on motor
The internal position units are interpolated encoder counts. The correspondence with the load

where:
Enc_periods
–
is the rotary encoder number of sine/cosine periods or lines per revolution
Interpolation
–
is the interpolation level inside an encoder period. Its a number power of 2
between 1 an 256. 1 means no interpolation
Encoder_accuracy
–
is the linear encoder accuracy in [m] for one sine/cosine period
Tr
–
transmission ratio between the motor displacement in SI units and load displacement
in SI units
6.2. Speed units
The internal speed units are internal position units / (slow loop sampling period) i.e. the position
variation over one slow loop sampling period
6.2.1.
Brushless / DC brushed motor with quadrature encoder on motor
The internal speed units are encoder counts / (slow loop sampling period). The correspondence
with the load
speed in SI units
