X Inv PSD Fault 690 Inverter power structure diagnostic fault: The safety control
system has detected a fault in one or more SGCTs. Incorrect
SGCT unit feedback was detected.
• Resolve all other faults first
• Ensure there are OIB2s are installed in the OIBBS, not the OIBs
• Ensure proper configuration setting of the SPS with drive hardware
• Check the LV wiring from the input device feedback
• Check the LV wiring/connectors to the OIBBS and ACB.
• Verify correct STO configuration settings
• Turn off all the power supplies to the drive and replace the SGCTs according to the
procedures in the User Manual.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare part(s)
for replacement.
X Inv S1 Stuck 672 Inverter S1 stuck: The inverter OIBBS diagnostic subsystem
has detected a fault.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Inv S2 Stuck 673 Inverter S2 stuck
: The inverter OIBBS diagnostic subsystem
has detected a fault.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Inv S3 Timeout 676 Inverter S3 timeout: The inverter OIBBS diagnostic subsystem
has detected a fault. A problem of timing function on the
OIBBS has been detected.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Inv STOInp Invld 675 Inverter safety input invalid: The inverter OIBBS diagnostic
subsystem has detected an invalid control input state.
• Verify the wiring of 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 Inv Temp Out Rng 667 Inverter temperature out of range
: The inverter OIBBS
diagnostic subsystem has detected an out of range
temperature.
• Verify the airflow in the low voltage control compartment.
• Shut off the control power to let the temperature in the control compartment cool.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X X X Inv TFBFbk Error 499 The drive has lost the fiber-optic signal from the specified
temperature feedback board.
• Verify that bit-1 of parameter P274 is set correctly.
• Check for damaged fiber-optic cable or loose connection.
X Inv WtchDg T Out 665 Inverter watchdog timeout: A failure of the Inverter OIBBS
diagnostic subsystem was detected.
• Verify all the connections for OIBBS, OIB2 on inverter side.
• This fault will only reset upon cycling control power.
• Cycle the control power, and if the same fault still trips the drive, contact the manufacturer
for spare parts of the OIBBS, OIB2 and/or the connections for replacement.
