96Warnings and AlarmsThe table below gives the drive’s warnings and alarms and indicateswhether the fault trip locks the drive. After a Trip Lock Fault, the inputpower must be removed, the cause of the fault corrected, and inputpower restored to reset the drive. A Trip can be reset manually in anyone of three ways.1) Pressing the keypad key RESET2) A digital input3) Serial communicationIn addition, an automatic reset may be selected in parameter 400,Reset Function which will reset all non-trip lock faults.Wherever an “X” is placed under both Warning and Alarm in the tablebelow, this means that a Warning precedes the Alarm. It can also meanthat it is possible to program whether a given fault is to result in aWarning or an Alarm. This is possible, for example, through parameter117, Motor Thermal Protection. After a trip, the motor will be coastingand the drive’s Alarm and Warning indications will flash. If the fault isremoved, only the Alarm will flash. After a reset, the drive will be readyto start operation again.No. Description Warning Alarm Trip Locked1 10 Volts low (10 VOLT LOW) X2 Live zero fault (LIVE ZERO ERROR) X X4 Mains failure (MAINS PHASE LOSS) X X X5 Voltage warning high (DC LINK VOLTAGE HIGH) X6 Voltage warning low (DC LINK VOLTAGE LOW) X7 Overvoltage (DC LINK OVERVOLT) X X8 Undervoltage (DC LINK UNDERVOLT) X X9 Inverter overloaded (INVERTER TIME) X X10 Motor overloaded (MOTOR TIME) X X11 Motor thermistor (MOTOR THERMISTOR) X X12 Current limit (CURRENT LIMIT) X X13 Over current (OVERCURRENT) X X14 Earth fault (EARTH FAULT) X X15 Switch mode fault (SWITCH MODE FAULT) X X16 Short-circuit (CURR.SHORT CIRCUIT) X X17 Serial communication timeout (STD BUSTIMEOUT) X X18 HPFB bus timeout (HPFB TIMEOUT) X X19 Fault in EEprom on power card (EE ERROR POWER) X20 Fault in EEprom on control card (EE ERROR CONTROL) X22 Auto-optimisation not OK (AMA FAULT) X29 Heat-sink temperature too high (HEAT SINK OVERTEMP.)
