Resolver (R) Module (RMC150)

Two Control Outputs and Two Resolver Inputs

The Resolver (R) module for the RMC150 interfaces to resolvers. The Resolver module front bezel is labeled RES.

Features

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

Wire the resolver according to the RMC150 Resolver Wiring topic.
Set the following parameters:
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:

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.
Otherwise, if a reference input axis (no output) uses input 0, then that axis will own the Axis 0 LED.
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:

If Drive 1 is assigned to an axis that has an input (i.e. isn't output-only), then that axis will own the Axis 1 LED.
Otherwise, if a reference input axis (no output) uses input 1, then that axis will own the Axis 1 LED.
Otherwise, if Drive 1 is assigned to an output-only axis, then that axis will own the Axis 1 LED.

LED Colors

State	Description
Steady Off	No power or the output/input is not assigned to an axis.
Steady Green	The axis is either in closed loop control or is a reference axis. The axis is not halted.
Flashing Green	The output is in open loop and the axis is not halted (not possible for reference axes).
Flashing Red	A Closed Loop Halt or External Halt has occurred because an error bit is set (not possible for reference axes). The LED will not turn red due to a halt caused by a halt command.
Steady Red	An Open Loop Halt or Direct Output Halt has occurred because an error bit is set (for reference axes, any halt has occurred). The LED will not turn red due to a halt caused by a halt command.
