Delta RMC151 - Manual (Page 687)

7 Hardware
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.
7.3.9. DI/O Module
7.3.9.1. DI/O Module (RMC150)
The Discrete I/O module for the RMC150 contains eight discrete outputs and eighteen discrete
inputs. The discrete I/O are compatible with signals ranging from 5 to 24 VDC.
Discrete I/O can be used for the following purposes:
• Turn outputs on and off with commands
• Use discrete I/O in User Programs
• Use discrete inputs to start User Programs
• Physical Limit Inputs
Part Number
The DI/O Module can be placed in slot 0, 3, 4, or 5 of the RMC150 backplane. However,
because the backplane connector of slot 0 (the leftmost slot) is different from that of slots
3-5, the part number of a DI/O module for slot 0 differs from a DI/O module for slots 3-5.
If placed in slot 0, the part number is DI/O. If placed in slots 3, 4, or 5, the part number
is Dn, where n is the number of D modules. Multiple Discrete I/O modules can be placed
in the same rack.
Slot Part Number
0 DI/O
This must be added to the end of the part
number, for example RMC150E-M1-H2-DI/O.
3-5 Dn
where x is the number of DI/O modules, for
example RMC150E-M1-D2.
