Chapter 1 Fault Messages
X RecHSnk OvrTemp 146 The drive detected that the rectifier heat sink temperature
has reached the trip setting. Be sure that the fan is working
properly and that the air flow is sufficient in this cabinet.
Confirm actual temperature in parameters is not higher than the trip value. If so, investigate
the conditions of the drive (ambient/ loading/ elevation / ventilation/ filter status /heatsink
clogging).
Check TFB and FOI board for power and fiber-optic integrity.
Check the sensor and temperature offline (ambient) for accuracy.
X RecChB OvrTemp 150 Not normally used. The drive has detected that the
temperature feedback from the optional temperature board
has reached the trip setting.
X RecHSnk Sensor 149 The drive has detected while not running 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 or over 100 °C, and both are
unrealistic values.
• Verify sensor is completely seated properly on TFB.
• Measure sensor resistance.
• Replace if necessary.
X RecChB Sensor 153 Not normally used. The drive while not running has detected
a missing temperature sensor connected to the optional
temperature feedback channel. Be sure that the sensor in
plugged in.
X RecFbrOpt Config 129 The drive has detected that the number of fiber-optic boards
does not match the number of devices.
• Verify the parameter settings.
• Check that the boards are plugged properly on the OIBB.
X Rec A1 Fault 645 Rectifier A1 fault
: The rectifier OIBBS diagnostic subsystem
has detected a fault.
• Ensure the OIB2s are installed in the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec A1 PwrSupply 646 Rectifier A1 power supply out of range: The rectifier OIBBS
diagnostic subsystem has detected a fault. A1 Boost converter
output voltage is out of range.
• Ensure OIB2s are installed in the OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec A2GateBufFlt 647 Rectifier A2 gate buffer fault: The rectifier OIBBS diagnostic
subsystem has detected a fault. A2, the gate buffer has
detected a fault.
• Verify all connections to the rectifier OIBBS.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for the OIBBS spare parts for
replacement.
X Rec Gate Act Flt 659 Rectifier gate active fault
: The safety control system has
detected a failure in the non safety-related drive control
system to perform an orderly shutdown in preparation for
activation of the safety function. The safety function has been
executed independent of the non safety-related control
system.
• Check LV wiring and connectors to OIBBS and the ACB.
• Verify the drive settings.
• Cycle the control power.
• If the same fault still trips the drive, contact the manufacturer for further actions.
X Rec General Flt 639 Rectifier general fault: This fault indicates a diagnostic of the
PSD test failed, a diagnostic of the power supply monitoring
failed, the input contactor power on timer has failed, or the
input contactor does not indicate closed when the drive is
running.
• 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.
