Front Panel Description
No. Name Description
(1) Power
ON A green LED that indicates +5 VDC power is
applied properly from the LEGEND-MC
amplifier to the controller.
(2) Alarm/
Error A red LED that will flash on initially at power up
and stay lit for approximately 1-8 seconds. After
power up, the LED will illuminate for the
following reasons:
•The axis has a position error greater than the error
limit. The error limit is set by using the command
ER.
•The reset line on the controller is held low or is
being affected by noise.
•There is a failure in the controller and the
processor is resetting itself.
•There is a failure in the output IC which drives
the error signal.
(3) CN6 9 pin male D-Sub serial port connector
(4) CN5 3M 50 pin high density I/O connector
(5) RST Reset switch. Causes the controller to reboot, and
load the application program and parameters from
flash. If the program contains an #AUTO label, it
will automatically execute.
(6) Ethernet
status A green LED that is lit when there is an Ethernet
connection to the controller. This LED tests only
for the physical connection, not for an active or
enabled link.
(7) Ethernet
status The yellow LED indicates traffic across the
Ethernet connection. This LED will show both
transmit and receive activity across the
connection. If there is no Ethernet connection or
IP address assigned, the LED will flash at regular
intervals to show that the BOOTP packets are
being broadcast.
