4-12 TroubleshootingI/O Faults and AlarmsThe table below contains a list of I/O-specific faults and alarms, the type offault or alarm, the action taken when the drive faults, the parameter used toconfigure the fault or alarm (if applicable), and a description and action(where applicable).Table 4.E I/O Fault and Alarm Types, Descriptions and ActionsEventFault Configuration AutoNo. (1) Fault/Alarm Text Type Action Parameter Reset Description/Action(s)xx000 No Entryxx001 Analog In Loss Configurable P53/P63Analog input has a lost signal.[Anlg InX LssActn]xx002 Motor PTC Trip Configurable P40Motor PTC (Positive Temperature Coefficient) over[PTC Cfg]temperature.xx005 Relay0 Life Configurable P106Predictive maintenance.[RO0 LifeEvntActn]xx006 Relay1 Life Configurable P116Predictive maintenance.[RO1 LifeEvntActn]xx010 Anlg Cal Chksum Non-Reset CoastThe checksum read from the analog calibration data doesFaultnot match the checksum calculated.

For open wire detection to work, the encoder signalsmust be differential (not single ended). The Z channel is onlychecked when enabled. See P1 [Encoder Cfg].xx001 Phase Loss Configurable P3More than 30 phase loss (open wire) events have occurred[Fdbk Loss Cfg]over an 8 millisecond time period. The same restrictions asfor Open Wire detection apply.xx002 Quadrature Loss Configurable P3Quadrature loss events occur when simultaneous edge[Fdbk Loss Cfg]transitions occur on both the A and B encoder channels.This fault will occur when more than 10 quad loss eventsover a 10 millisecond time period are detected. Only validwhen both A and B channels are used (not Bit 1 “A ChanOnly”) in P1 [Encoder Cfg].xx058 Module Defaulted Fault Coast Module was commanded to write default values.(1) xx indicates the port number.
