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.
7.3.5. MDT Module
7.3.5.1. MDT (M) Module (RMC150)
The MDT module for the RMC150 interfaces to Magnetostrictive Displacement Transducers
(MDTs). These absolute-position transducers are especially well suited for hydraulic
applications because of their non-contact design, robustness, modularity, and resistance to
contaminants. The RMC150 MDT module supports transducers with Start/Stop and Pulse Width
Modulated (PWM) outputs. The RMC150 can be configured to trigger from the rising or falling
edges on Start/Stop transducers. MDTs with SSI output are supported by the RMC150 SSI
Module.
See the MDT Fundamentals topic for details on how MDT feedback works.
Features
• Two axes of MDT feedback per module
• Up to 0.001” resolution using Start/Stop
• Up to 0.0001” resolution using PWM with multiple recirculations
• Supports internal transducer recirculations
• Transducer length up to 398 inches (10.1 m) (4 ms loop time)
• Differential (recommended) or single-ended interface
• Two isolated, ±10 V, 12-bit control outputs per module
• Current output up to ±200 mA with VC2124 converter option
Part Number
The part number of the MDT module is Mn, where n is the number of MDT modules.
