Chapter 1 Fault Messages
X Input Prot’n #1 32 Standard external fault/warning input included allowing the
end-user to install a protective relay (for example, input feed
protection relay) auxiliary contact that can activate a drive
fault or warning, depending on configuration of InputProt1
Class (P440).
• Check device responsible for the auxiliary contact to this input and investigate the fault
indicated by the device’s fault message.
• Investigate internal and external causes for this fault code.
• Check the 120V signal through the external device.
• Check the XIO board inputs and parameter status bits.
X InputProt’n #2 36 Standard external fault/warning input included allowing the
end-user to install a protective relay (for example, input feed
protection relay) auxiliary contact that can activate a drive
fault or warning, depending on configuration of InputProt2
Class (P444).
• Check device responsible for the auxiliary contact to this input and investigate the fault
indicated by the device’s fault message.
• Investigate internal and external causes for this fault code.
• Check the 120V signal through the external device.
• Check the XIO board inputs and parameter status bits.
• REVISION 9003 and higher, this input is dedicated to line filter capacitor protection. An
open circuit on this input will trigger the line filter capacitor protection. For additional
information see fault code 135
X Inv A1 Fault 677 Inverter A1 fault
: The inverter OIBBS diagnostic subsystem
has detected a fault.
• Ensure the OIB2s are installed in the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Inv A1 PwrSupply 678 Inverter A1 power supply out of range: The inverter OIBBS
diagnostic subsystem has detected a fault. A1 boost converter
output voltage is out of range.
• Ensure OIB2s are installed in the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X InvA2D Convrsion 189 This fault indicates that the analog to digital converters on the
ACB were not able to completely transmit the data to the slave
processor using the DMA within the sampling period.
• Cycle control power to see if the fault remains, and replace the ACB or DPM.
X Inv A2GateBufFlt 679 Inverter A2 gate buffer fault
: The inverter OIBBS diagnostic
subsystem has detected a fault. A2, the gate buffer has
detected a fault.
• Verify all the connection to the inverter OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X InvAnlg SelfTest 186 On power up the drive has detected that dc offset on some
analog feedback channels is high. The offending channels are
indicated by parameters InvAnlg SelfTst1 (P96) and InvAnlg
SelfTst2 (P251) in the Diagnostic group.
• Cycle control power to see if the fault remains, and replace the ACB if necessary.
• Using a multimeter, check the DC offset on the circuit when this fault is present. The
feedbacks that cause this fault can be determined by looking at parameter (P96 and P251)
in the Diagnostic group.
• See Technical Note PF7000_GEN-12, Line/Motor ADC/DAC Faults on Initial Power-Up
• See Technical Note PF7000-4

X Inv Gate Act Flt 691 Inverter gate active fault: The safety control system has
detected a failure in the non safety-related drive control
system to perform an orderly shutdown in preparation for
activation of the safety function. The safety function has been
executed independent of the non-safety related control
system.
• Check LV wiring/connectors to OIBBS and ACB.
• Verify the drive settings.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for further actions.
