6.11.5. Step motor open-loop control. Incremental encoder on load
In open-loop control configurations with incremental encoder on load, the motor position is not
computed.
6.11.6. Step motor closed-loop control. Incremental encoder on motor
The internal motor position units are motor encoder counts. The correspondence with the motor
position in SI units is:

where:
No_encoder_lines
–
is the motor encoder number of lines per revolution
6.11.7. Brushless motor with sine/cosine encoder on motor
The internal motor position units are interpolated encoder counts. The correspondence with the
motor position in SI units is:

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
6.12. Motor speed units
6.12.1. Brushless / DC brushed motor with quadrature encoder on motor
The internal motor speed units are encoder counts / (slow loop sampling period). The
correspondence with the motor
speed in SI units is:
For rotary motors: ] IU [ Speed _ Motor
