Message Description
SYSTEM MODULE GROUND FAULT T he 1394 systemmodulehas detecteda ground fault. The system generatesa ground fault
whenthere isan imbalancein the DCbusofgreater than5A. Thisdrive errorcan becausedby
incorrectwiring(verifymotorand ground wiring),motormalfunction,oran axis module IGBT
malfunction.
SYSTEM MODULE OVER TEMP The 1394contains athermalsensorwhichsensestheinternal ambienttemperature. Causes
couldbe:thatthe cabinet ambienttemperatureisabove rating. T he machinedutycycle
requires an RMS currentexceeding the continuous rating ofthe controller. The airflowaccessto
the 1394 is limited orblocked. This does notnecessarilyindicate amotorovertemperature.
Motorovertemperturesensorsshouldbe wired directly into the E-Stop string.
SYSTEM MODULE OVER VOLTAGE T he 1394 systemmodulebuss voltageexceeds the maximumoperating voltage. The dcpower
busis continuouslymonitored. Ifitexceeds a preset level (810Vdc),afaultis sensedand the
powersupplyisdisabled. There are severalpossiblecauses forthis error.
• an undersized shuntrequirement
• a blown shunt regulatorfuse
• 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
• thesystem inertia is too high causing excessive energy to be returned to thepowersupply bus
• a vertical axis with insufficient counterbalancing is overdriv ing the servomotor and causing excessive
energy to be returned to the power supply bus
• an incorrect power supply is installed in your system. Makesure you are usinga CNC
power supply
SYSTEM MODULE PHASE LOSS T h e 1394 systemmodulehas detected a loss ofoneoftheinputpowerphases. The
three--phase input line ismonitored and a faultwillbe issued whena phaselossisdetected.
Typicalcausesinclude,oneormoreinputlinefuses haveopened,contactormalfunction,or
incorrect wiring.
SYSTEM M ODULEUNDER VOLTAGE The 1394 systemmodulevoltage doesnotmeetthe minimumoperatingvoltage. The DCpower
bussshallactivatetheundervoltagelimitwhen the busdropsto 275 VDCor less. Itwillclearat
300 Vdc. Typicalcauses include low voltage onthethree phaseinput.

THREAD FEEDRATE TOO LARGE Thelead is too large inthreading mode. Programslower spindle speed.
THREAD LEAD ERROR T he thread lead wastoolargeortoosmall. Thiscommonly occurswhen cutting a variable
