Warning Messages Chapter 2
Rec DC Cur Gain 172 The current gain calculated for DC link current sensing is lower
than expected.
• Verify that the HECS ratio and burden resistor match the drive/
motor ratings.
Rec Gate Pwr Sup 173 Rectifier gate driver power supply warning.
This warning is for SGCT based drives and indicates a problem
with the gate power supply associated with a particular device
which is also likely in the warning queue.
• The device feedback was not correct due to power loss to the gate
driver board.
• This can be from the 20V DC output of the IGDPS or on the gate driver
board itself.
• This warning can also appear as a result of another device fault such as
an Online fault.
• This warning can also come if the device has failed.
RecHSnk FbrOptic 170 While Not Running, the fiber-optic signal from the TFB on the
Rectifier Heatsink, connected to Channel A fiber-optic receiver
RX7 on FOI-L-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 boards for power.
• Verify that the fiber-optic cables are properly seated in the
transmitters and receivers.
• Check the fiber-optic cables for kinks, bends and/or 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.
RecChB FbrOptic 171 Not normally used: While Not Running, the fiber-optic signal
from the optional TFB connected to channel B fiber-optic
receiver RX7 on FOI-L-B is not present. This is only a fault while
not running. If this occurs while running it will appear as a
warning.
RecHSnk OvrTemp 162 The drive detected that the heat sink temperature has reached
the alarm level.
• Confirm the actual temperature in parameters is not higher than
the warning value. If the actual temperature is higher than the
warning level value, investigate the conditions of the drive
(ambient / loading / elevation / ventilation/ filter status / heatsink
clogging).
• Verify that the trip and warning settings match the factory
recommended values.
• Check the TFB and FOI boards for power and fiber-optic integrity.
• 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.
RecChB OvrTemp 163 Not Normally Used – The temperature detection on a Rectifier
Heatsink. The drive has detected that the temperature
feedback from the optional temperature board has reached the
warning level.
RecHSnk Sensor 168 While running, the drive has detected a missing temperature
sensor connected to the TFB on the rectifier heatsink. A missing
sensor can result in either a Fiber Optic Loss fault or a Sensor
fault because a missing sensor can be interpreted as either 0°C
(32 °F) or over 100°C (212 °F), and both are unrealistic values.
• Verify that the sensor is completely seated properly on the TFB.
• Measure the sensor resistance. Replace if necessary.
• 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.
RecChB Sensor 169 Not normally used: While running, the drive has detected a
missing temperature sensor connected to the optional TFB
connected to the fiber-optic receiver RX7 on FOI-L-B. A missing
sensor can result in either a Fiber Optic Loss fault or a Sensor
fault because a missing sensor can be interpreted as either 0°C
(32 °F) or over 100°C (212 °F), and both are unrealistic values.
