RMC70/150 and RMCTools User Manual
Part Number
The part number of the Resolver module is Rn, where n is the number of Resolver
modules.
For example, RMC150E-R1 is an RMC150E with one Resolver module. RMC150E-R3-Q1 is
an RMC150E with three Resolver modules and one Quadrature module.
Setting Up the Resolver Module
1. Wire the resolver according to the RMC150 Resolver Wiring topic.
2. Set the following parameters:
• Resolver Resolution
• Reference Amplitude
• Reference Frequency
3. Scale the axis. Typically, resolvers will use Rotary Scaling. Notice that one revolution
of the resolver will always consist of 65,536 counts on the RMC, regardless of the
resolver resolution parameter.
