Fault Messages Chapter 1
X IGDPS 56V Loss 53 The drive has detected a loss of the 56V dc voltage feeding the
IGDPS.
• Check connections, the DC output of the AC/DC converter and the input voltage to the
IGDPS.
• Replace the power supply if required.
• Measure the voltage at the ACB connector J15 and compare it to parameter P101. P101
provides the value the drive processor board measures. If the actual value at J15 is 56V and
P101 is lower than 56V, then problem is either the ACB or DPM—most likely the ACB.
X X InputLockOut 5Min 462 This fault is valid for 18-pulse drives and prevents damage to
the isolation transformer. The input contactor has been locked
out for 5 minutes due to a Line OverCurrent condition.
• Investigate the cause of the over-current condition. Fault can only be reset after 5 minutes.
• Check the rectifier SCRs for short across anode to cathode
X X InputLockOut Indef 463 This fault is valid for 18-pulse drives and prevents damage to
the isolation transformer. The input contactor has been locked
indefinitely due to a Line OverCurrent condition.
• It is likely that there is line to line short condition due to shorted SCR devices.
• Investigate the cause of the over-current condition.
• If nothing found short, cycle control power to reset the fault.
X Inv Airflow Loss 495 The cooling airflow velocity on the specified power stack is
below the trip/warn level.
• Ensure that there are no obstructions to the path of the incoming/outgoing air flow.
• Check for cooling fan deterioration.
• Verify if the trip (P840) and warn setting (P841) matched factory recommended values.
X InvA2D Seq Error 188 An error has been detected in A2D conversion. • Cycle control power.
• If the fault does not clear after cycling the control power, then replace ACB Board. If this
does not resolve the issue, then replace DPM board.
X InvFbrOpt Config 187 The drive has detected that the number of fiber-optic boards
does not match the number of devices in the inverter section.
• Verify the parameter settings and check that the board in plugged properly on the OIBB.
X X X Inv Hs Over Temp 491 The drive detected high heatsink temperature at the specified
location.
• Verify if the warn (rectifier P112, inverter P316) and trip settings (rectifier P111, inverter
P315) match factory recommended values.
X X X InvHSnk FbrOptic 180 While Not Running, the fiber-optic signal from the TFB on the
inverter heatsink, connected to Channel A fiber-optic receiver
RX7 on FOI-M-A is not present. This is only a fault while not
running. If this occurs while running it will appear as a
warning.
• Check TFB and FOI board for power.
• Check the fiber-optic cables are properly seated in the transmitters and receivers.
• Check the fiber-optic cable for kinks, bends, breaks that could be blocking the signal.
• This can occur if the sensor is not connected to the TFB.
X X X InvHSnk LowTemp 179 If the measured temperature IHeatsink Temp C (P252) is less
than 2 °C, and the drive is not running, the drive will display
this fault.
• Verify that the ambient in the control room is not below 2 °C (35.6 °F).
• Verify power to the TFB.
• There could be a mechanical problem with the temperature sensor or with the cable
feeding the signal back to the TFB.
• Swap with the rectifier hardware to identify the bad component.
