Figure 10.6  - Mathematical model of the motor and amplifier in three operational modes

Encoder

The encoder generates N pulses per revolution.  It outputs two signals, Channel A and B, which are in quadrature. 
Due to the quadrature relationship between the encoder channels, the position resolution is increased to 4N 
quadrature counts/rev.

The model of the encoder can be represented by a gain of

Kf = 4N/2

π

       [count/rad]

For example, a 1000 lines/rev encoder is modeled as

Kf = 638

DAC

The DAC or D-to-A converter converts a 16-bit number to an analog voltage.  The input range of the numbers is 
65536 and the output voltage range is +/-10V or 20V.  Therefore, the effective gain of the DAC is

K= 20/65536 = 0.0003 [V/count]
