Chapter 2 Warning Messages
IxoTx Fans On 207 Isolation transformer fan ON warning
This warning is for drives with redundant isolation transformer
fan option. The drive detected the loss of fan 2 and starts fan 1.
Investigate the fan 2 loss and verify fan 1 operation. Reset
warning at next shutdown and fan 2 will start running
• Isolation transformer fan status is high while it should be low.
• Investigate the control circuit for isolation transformer fan.
• Check the wiring at XIO for fan status.
InpCtctrFeedback 159 The drive has detected the presence of medium voltage but is
not sensing the input contactor status.
• Verify that the contactor is closed.
• Confirm the feedback path from the contactor auxiliary contact to
the contactor status input string on the ACB.
• Verify the contactor status string (MSR contact, DIC contact, DI aux
contact, etc.).
• Confirm that the drive is commanding the contactor to close (DIC
relay). If not, determine why the contactor was commanded to
close. If DIC relay is not energized, the contactor should not be
allowed to close.
InvHSnk FbrOptic 220 While 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 the TFB and FOI board for power.
• Check that the fiber-optic cables are properly seated in the
transmitters and receivers.
• Check the fiber-optic cables for kinks, bends, breaks that could be
blocking the signal.
• This can occur if the sensor is not connected to the TFB.
• NOTE: This is a warning because the drive should not fault on the
loss of the signal while running. There is no imminent danger to the
drive, but the user needs to be aware that there is a temperature
feedback signal missing.
InvHSnk OvrTemp 216 The temperature detection on the inverter heatsink, connected
to channel A fiber-optic receiver RX7 on FOI-M-A, has exceeded
inverter heatsink temperature warning (P316).
• Confirm that the actual temperature in parameters is not higher
than the warning value. If so, investigate the conditions of the drive
(ambient / loading/ elevation / ventilation/ filter status / heatsink
clogging).
• Check the sensor and temperature offline (ambient) for accuracy.
• Be sure that the fan is working properly and that the air flow is
sufficient in this cabinet.
Inv AC Cur Gain 223 The current gain calculated for motor current sensing is outside
the limit of the expected range [2…5] pu.
• Verify that the HECS ratio and burden resistor match the drive/
motor ratings.
Inv AirflwSensor 395 The specified airflow velocity reading is out of normal range. • Ensure that the airflow sensor is correctly plugged in and is not
damaged.
Inv Ambient Loss 447 The specified ambient temperature reading is out of normal
range.
• Ensure that the on-board temperature sensor is not damaged. If an
external sensor is used, ensure that the sensor is correctly plugged
in and is not damaged.
Inv High Ambient 442 The drive detected high ambient temperature at the specified
location.
• Verify if the warning setting (P571) matches factory recommended
value.
