LED Indicators
There are seven LED status indicators on the DSM314 module, described below:
STAT
Normally ON. FLASHES to provide an indication of operational errors. Flashes
slow
(four times/second) for Status-Only errors. Flashes
fast
(eight times/second) for errors
which cause the servo to stop.
ON:
When the LED is steady ON, the DSM314 is functioning properly. Normally,
this LED should always be ON.
OFF:
When the LED is OFF, the DSM314 is not functioning. This is the result of a
hardware or software malfunction which will not allow the module to power up.
Flashing:
When the LED is FLASHING, an error condition is being signaled.
Constant Rate, CFG LED ON
:
The LED flashes slow (four times/second) for Status Only errors and fast (eight
times/second) for errors which cause the servo to stop. The
Module Error
Present
%I status bit will be ON. An error code (hex format) will be placed in
the
Module Status Code
%AI word or one of the
Axis Error Code
%AI words.
Constant Rate, CFG LED Flashing
:
If the STAT and CFG LEDs both flash
together
at a constant rate, the DSM314
module is in boot mode waiting for a new firmware download. If the STAT and
CFG LEDs both flash
alternately
at a constant rate, the DSM314 firmware has
detected a software watchdog timeout due to a hardware or software
malfunction.
Irregular Rate, CFG LED OFF
:
If this occurs immediately at power-up, then a hardware or software malfunction
has been detected. The module will blink the STAT LED to display two error
numbers separated by a brief delay. The numbers are determined by counting
the blinks in both sequences. Record the numbers and contact GE Fanuc for
information on correcting the problem.
OK
The OK LED indicates the current status of the DSM314 module.
ON:
When the LED is steady ON, the DSM314 is functioning properly. Normally,
this LED should always be ON.
OFF:
When the LED is OFF, the DSM314 is not functioning. This is the result of a
hardware or software malfunction which will not allow the module to power up.
CFG
This LED is ON when a module configuration has been received from
the PLC.
EN1
When this LED is ON, the Axis 1 Drive Enable relay output is active.
EN2
When this LED is ON, the Axis 2 Drive Enable relay output is active.
EN3
When this LED is ON, the Axis 3 Drive Enable relay output is active.
EN4
When this LED is ON, the Axis 4 Drive Enable relay output is active.
