Error and System Messages

Appendix B

B-42

Message Description

SYSTEM MODULE GROUND F AULT The 1394 system modulehasdetected a ground fault. The systemgenerates a ground fault

when thereis an imbalance in theDCbusof greaterthan 5A. This drive errorcan be caused by

incorrect wiring (verifymotor and ground wiring),motormalfunction,or an axis moduleIGBT

malfunction.

SYSTEM MODULE OVER TEMP The 1394 containsa thermal sensorwhich sensesthe internalambienttemperature. Causes

could be:thatthecabinetambienttemperature is above rating. The machinedutycycle

requiresan RMScurrentexceeding thecontinuousrati ng of thecontroller. The airflow accessto

the1394 is limitedorblocked. Thisdoesnot necessarilyindicatea motorovertemperature.

Motorovertemperture sensorsshould be wired directlyintothe E-Stopstring.

SYSTEM MODULE OVER VOL TAGE The 1394 systemmodule buss voltageexceedsthemaximumoperatingvoltage. T he dcpower

busiscontinuouslymonitored. Ifit exceedsa presetlevel(810V dc),a faultissensed and the

powersupplyis disabled. T here are severalpossible causesforthiserror.

• an undersized shuntrequirement

• a blown shunt regulator fuse

• a malfunctioning shunt regulator transistor

• the power driver board is malfunctioning and incorrectly sensing the bus voltage

• an incorrectly set CNC acc/dec rate

• an excessive input line voltage

• the system inertia is toohigh causing excessiveenergy to bereturnedto thepower supply bus

• a vertical axis with insufficient counterbalancing is overdriving the servomotor and causing excessive

energy to be returned to the power supply bus

• an incorrect power supply is installed in your system. Make sure you are usinga CNC

power supply

SYSTEM MODULE PHASE LOSS The 1394 systemmodulehasdetected a loss ofone of the inputpowerphases. T he

three --phaseinput line is monitored and a faultwill be issuedwhen a phase loss isdetected.

Typical causesinclude, one ormoreinput line fuseshave opened,contactormalfunction, or

incorrectwiring.

SYSTEM MODULE UNDER VOLTA GE The 1394 systemmodule voltage doesnotmeet theminimum operatingvoltage. T he DC power

bussshall activate theunder voltagelimitwhen thebusdrops to275VDCor less. Itwillclearat

300 Vdc. Typical causesinclude low voltageonthethreephaseinput.
