Error Reporting
GFK-1742A Appendix A Error Reporting A-17
A
1 Motor power wiring (U, V and W) may be shorted to ground or connected with improper
phase connections. Check the wiring and connections. Check the servomotor for shorts to
motor frame. Replace the motor if shorted.
2 Improper motor type code may be configured or excessive values for tuning parameters.
Confirm that the proper motor is configured and lower gain values.
3 The amplifier maintenance manual will describe the procedure for monitoring motor current
signals (IR and IS). If the waveforms are abnormal replace the amplifier. If excessive noise is
observed check grounds and especially the cable shield grounds for the command cable (K1)
to the amplifier.
4 The motor may be operating in violation of duty cycle restrictions. Calculate the amount of
cooling time needed based on the duty cycle curves published for the particular motor.
5 The motor may be over loaded. Check for excessive friction or binding in the machine.
6 For all the above problems, allow ten minutes cooling of the amplifier with minimum or no
motor loading then cycle amplifier power to reset.
LED Indicators
There are seven LEDs on the DSM314 module which provide status indications. These LEDs are
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 that 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 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 that will not allow the module to power up.
