Quadrature with Analog Output 6.3
Transducer Interface Modules 6-31
We begin by calculating the exact Scale:
With the exact Scale value, we must choose the Prescale Divisor and the rounded Scale value.
The highest divisor value we can use is 8. Multiplying the exact scale by this divisor value and
rounding gives us the following parameters:
Scale = 30418
Prescale Divisor = 8
Next, we must calculate the offset:

6.3.1 Quadrature with Analog Output Overview
The QUAD module is one of two RMC modules with an interface for quadrature encoder
feedback. This module provides analog drive output, while the STEP interface module provides
stepper drive output. Together, these modules allow the RMC100 series motion controllers to
control a wide range of motors and linear actuators with quadrature encoder feedback. For details
on the STEP module, see Quadrature with Stepper Output Overview.
