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:
1. 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.
2. Otherwise, if a reference input axis (no output) uses input 1, then that axis will own
the Axis 1 LED.
3. 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.
7.3.6. SSI Module
7.3.6.1. SSI (S) Module (RMC150)
Important!
The SSI module requires RS-422 (5V differential) SSI inputs. It does not support single-ended
SSI inputs or higher voltage inputs.
The SSI module for the RMC150 interfaces to feedback devices using the Synchronous Serial
Interface (SSI) standard. Many types of transducers are available with SSI, including
magnetostrictive displacement transducers (MDTs), absolute encoders, and laser measuring
devices. SSI has a number of advantages over other transducer interfaces. First, it offers
higher noise immunity. Second, it gives absolute positions. Third, it supports a wide variety of
