Parameters and firmware blocks196Group 46 FAULT FUNCTIONSDefinition of drive behaviour upon a fault situation.An alarm or a fault message indicates abnormal drive status. For the possiblecauses and remedies, see chapter Fault tracing.46Firmware block:FAULT FUNCTIONS(46)This block• configures supervision of externalfaults by defining the source (forexample, a digital input) for externalfault indication signal• selects the reaction of the drive(alarm; fault; continuation at safespeed in some cases) uponsituations like local controlcommunication break, motor/supplyphase loss, earth fault, or SafeTorque Off function activation• shows the codes of the latest faults,the time at which the active faultoccurred, and the alarm words.Block inputs located in otherparameter groups22.10 SPD SUPERV EST (page 153)22.11 SPD SUPERV ENC (page 153)22.12 SPD SUPERV FILT (page 153)Block outputs located in otherparameter groups8.01 ACTIVE FAULT (page 113)8.02 LAST FAULT (page 113)8.03 FAULT TIME HI (page 113)8.04 FAULT TIME LO (page 113)8.05 ALARM LOGGER 1 (page 113)8.06 ALARM LOGGER 2 (page 114)8.07 ALARM LOGGER 3 (page 114)8.08 ALARM LOGGER 4 (page 115)8.09 ALARM LOGGER 5 (page 115)8.10 ALARM LOGGER 6 (page 115)8.15 ALARM WORD 1 (page 116)8.16 ALARM WORD 2 (page 116)8.17 ALARM WORD 3 (page 117)8.18 ALARM WORD 4 (page 117)FAULT FUNCTIONS 33MISC_3 2 msec (10)22.10 SPD SUPERV EST(Drive value)22.11 SPD SUPERV ENC(Drive value)22.12 SPD SUPERV FILT(Drive value)< 46.01 EXTERNAL FAULT(Drive value)46.02 SPEED REF SAFE(Drive value)46.03 LOCAL CTRL LOSS(Drive value)46.04 MOT PHASE LOSS(Drive value)46.05 EARTH FAULT(Drive value)46.06 SUPPL PHS LOSS(Drive value)46.07 STO DIAGNOSTIC(Drive value)46.08 CROSS CONNECTION(Drive value)46.09 STALL FUNCTION(Drive value)46.10 STALL CURR LIM(Drive value)46.11 STALL FREQ HI(Drive value)46.12 STALL TIME(Drive value)8.01 ACTIVE FAULT8.02 LAST FAULT8.03 FAULT TIME HI8.04 FAULT TIME LO8.05 ALARM LOGGER 18.06 ALARM LOGGER 28.07 ALARM LOGGER 38.08 ALARM LOGGER 48.09 ALARM LOGGER 58.10 ALARM LOGGER 68.15 ALARM WORD 18.16 ALARM WORD 28.17 ALARM WORD 38.18 ALARM WORD 4
