Fault Messages Chapter 1
X Inv General Flt 671 Inverter general fault: The SGCTs have passed their
operational lifetime and maintenance needs to be completed.
• Verify the LV connections and configuration of the input device feedback to the OIBBS.
• Verify the drive configuration
• Cycle the control power
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare part
replacement.
X Inv Heartbeat 132 The master processor has detected that the slave DSP
software has either over-run or failed to initialize.
• Verify DC Control voltages on ACB.
• Cycle power and replace DPM board if necessary.
X X X InvHS TempSensor 503 The specified temperature reading is out of normal range. • Verify that bit-1 of parameter P274 is set correctly.
• Ensure that the temperature sensor is correctly plugged in and is not damaged.
X Inv InpCtctrClsd 689 Inverter input contactor closed
: The safety control system has
detected a fault in the drive input contactor control system.
The input device indicates closed when it was commanded to
open by the OIBBS.
• Verify the input contactor. In case the contactor has any problem(s), stop running the drive
and contact the manufacturer.
• Verify the low voltage wiring of the input contactor / circuit breaker control command.
• Verify the low voltage wiring of input contactor feedback.
• Cycle the control power.
X Inv NSR PS Rng 668 Inverter non safety-related power supply out of range: The
inverter OIBBS diagnostic subsystem has detected an out of
range power supply voltage of the 24Vdc power supply.
• Verify the STO system power supply/connection to the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for spare parts of the power
supply and/or OIBBS for replacement.
X Inv OIB Detected 688 Inverter OIB detected
: The safety control system has detected
incompatible hardware. One or more OIBs have been
detected.
• Verify the board mounted on the inverter OIBBS. It should be OIB2, not OIB.
• In case OIB(s) is/are applied, contact the manufacturer for the OIB2 spare parts for
replacement.
X Inv OvrVoltage 160 The inverter output voltage given by Inv Output Volt (P761)
has exceeded the trip settings. This is detected by the
hardware circuit in the ACB.
• This is drive output Voltage [ESP Surface Volt (P760) terminology used in ESP application].
• The protection uses P193 setting but drive calculates the motor filter cap voltage.
• In ESP application Inverter voltage may be different from motor voltage due to long cable
drop.
• Check the voltage sensing board for any resistor failure.
• Check for any open circuit at the drive output.
• Check the devices at the inverter.
X Inv PS Out Rng 666 Inverter power supply out of range: The inverter OIBBS
diagnostic subsystem has detected an out of range power
supply voltage on the internally generated supplies.
• Verify the STO system power supply/connection to the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for spare parts for the
power supply and/or OIBBS for replacement.
