10.3 FAULT CODESTable 61: Fault codesFaultcodeFault ID Fault name Possible cause How to correct the fault1 1 Overcurrent (hard-ware fault)There is too high a current(>4*I H) in the motor cable.Its cause can be 1 of these.• a sudden heavy loadincrease• a short circuit in themotor cables• the motor is not thecorrect typeDo a check of the loading. Do acheck of the motor. Do a check ofthe cables and connections. Makean identification run. Do a check ofthe ramp times.2 Overcurrent (softwarefault)2 10 Overvoltage (hard-ware fault)The DC-link voltage ishigher than the limits.• too short a decelera-tion time• high overvoltage spikesin the supply• Start/Stop sequencetoo fastSet the deceleration time longer.Activate the overvoltage controller.Do a check of the input voltage.11 Overvoltage (softwarefault)3 20 Earth fault (hardwarefault)The measurement of cur-rent tells that the sum of themotor phase current is notzero.• an insulation malfunc-tion in the cables or themotorDo a check of the motor cables andthe motor.21 Earth fault (softwarefault)5 40 Charging switch The charging switch is open,when the START commandis given.• operation malfunction• defective componentReset the fault and restart thedrive. If the fault occurs again, askinstructions from the distributornear to you.7 60 Saturation• Defective componentThis fault cannot be reset from thecontrol panel. Switch off the power.DO NOT RESTART THE DRIVE orCONNECT THE POWER! Askinstructions from the factory. If thisfault shows together with F1, do acheck of the motor cables andmotor.VACON · 172 FAULT TRACING10 TEL. +358 (0)201 2121 · FAX +358 (0)201 212 205
