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.
7.3.4.2. Analog (A) Module (RMC150)
Four 12-bit Analog Inputs
The Analog (A) module for the RMC150 provides four 12-bit resolution analog voltage or
current inputs. This module does not include control outputs. The Analog (A) module is
typically used for reference inputs, such as from a joystick, or for the secondary input of a
position-pressure or position-force axis. The Analog (H) module front bezel is labeled Analog
Inputs.
In addition to the Analog (A) module, the RMC150 supports the following analog modules:
 Analog (H) Module
Two control outputs and four 16-bit inputs for controlling position, velocity, pressure,
or force.
 Analog (G) Module
Two control outputs and two 16-bit analog voltage inputs for voltage-feedback
position, velocity, pressure, or force control applications.
Features
• Four isolated 12-bit inputs
• 8 times oversampling
• ±10 V, ±5 V, and 4-20 mA input ranges
• +10 V exciter output
Part Number
The part number of the Analog (A) module is An, where n is the number of Analog (A)
modules.
For example, RMC150E-M1-A1 is an RMC150E with one MDT and one Analog (A) module.
RMC150E-S2-A2 is an RMC150E with two SSI and two Analog (A) modules.
