953 Fault Status B
Fault Status B
RO 32-bit
Integer
Indicates the occurrence of conditions that have been configured as faults.
Bit 0 “Aux InputFlt” –
Bit 1 “OverVoltage” – Over voltage trip occurred.
Bit 2 “Drive OL” – Indicates the drive is overloaded. P940 [Drive OL Count] reached 100%.
Bit 3 “Heatsink OT” – Indicates the drive heatsink is over temperature. P943 [Drive Temp Pct] reached 100%.
Bit 4 “TransistorOT” – Indicates the transistor (IGBT) junction is over temperature. P941 [IGBT Temp Pct] reached 100%.
Bit 5 “SinkUnderTmp” – Indicates the heatsink temperature is under -18.7 °C (-2 °F).
Bit 6 “Excess Load” – Motor did not come up to speed in the allotted time during autotune.
Bit 7 “Overspd Lmt” – When set, indicates that a F25 “OverSpeed Limit” fault has occurred. This is a non-configurable fault. An overspeed condition results when
the motor speed falls outside of its normal operating range. The limits of this range are established by P521 [Max Rev Speed] - P524 [Overspeed Limit] = (lower
limit) and P520 [Max Fwd Speed] + P524 [Overspeed Limit] = (upper limit). In flux vector control mode or scaler control mode with encoder, the motor speed used
is a 2msec averaged value of P131 [Active Vel Fdbk]. In scaler control mode without an encoder, the overspeed check uses P1 [Output Frequency]. The overspeed
condition must exist for at least 16 milliseconds before it causes a fault to occur.
Bit 8 “Prchrg Open” – Precharge relay is open.
Bit 9 “SafetyBrdFlt” – Safety board is in a faulted state.
Bit 10 “IRVoltsRange” – The Autotune IR voltage exceeded the range of P73 [IR Voltage Drop].
Bit 11 “FluxAmpsRang” – The Autotune Flux Current exceeded the range of P75 [Flux Current Ref].
Bit 12 “IXOVoltRange” – The Autotune Ixo voltage exceeded the range of P74 [Ixo Voltage Drop].
Bit 13 “AuRstExhaust” – The value set in P348 [Auto Rstrt Tries] has been exceeded.
Bit 14 “SW OverCur” – Drive output current has exceeded the 1ms 250% current rating.
Bit 15 “HW OverCur” – Drive output current has exceeded the hardware current trip limit.
Bit 16 “TrqPrvSpdBnd” – The allowable deviation between actual motor speed and ramped speed set in P1105 [Speed Dev Band] has been exceeded.
Bit 17 “TPEnclsCfg” – The Torque Proving function has been configured as Encoderless. Read the Attention statement under Lifting/Torque Proving on page 356
.
Bit 18 “Ground Fault” – Current path to earth ground greater than 25% drive rated current detected.
Bit 19 “OW Alarm TO” – An A65 “OW TrqLvl Timeout” alarm has occurred.
Bit 20 “Over Travel” – The selected digital input for one of the over travel directions is active.
Bit 21 “TrvlLimCflct” – Travel limits are in conflict.
Bit 22 “End Lmt Sw” – The selected digital input for one of the end limit switches, P196 [DI Fwd End Limit] or P198 [DI Rev End Limit], has detected a falling edge
and P313 [Actv SpTqPs Mode] is not set to 1 “Speed Reg.”
