RMC70/150 and RMCTools User Manual
The part number of this Resolver module is RWn, where n is the number of Resolver
modules.
For example, RMC150E-RW1 is an RMC150E with one Resolver (RW) module. RMC150E-
RW3-Q1 is an RMC150E with three Resolver (RW) modules and one Quadrature module.
Setting Up the Resolver Module
1. Wire the resolver according to the RMC150 Resolver Wiring topic.
2. Set the Resolver Resolution.
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.

LEDS
Axis 0 LED
Axis LED applies to the Drive 0 output or feedback input 0 as described below:
1. If Drive 0 is assigned to an axis that has an input (i.e. isn't output-only), then that
axis will own the Axis 0 LED.
2. Otherwise, if a reference input axis (no output) uses input 0, then that axis will own
the Axis 0 LED.
3. Otherwise, if Drive 0 is assigned to an output-only axis, then that axis will own Axis 0
LED.
Axis 1 LED
Axis 1 LED applies to the Drive 1 output or feedback input 1 as described below:
