PowerFlex® 755 AC Drives provide ease of use, application flexibility, and high performance. They include multiple control and hardware options, as well as optional embedded safety features. These drives are well-suited for a wide variety of motor control applications including pumps, fans, and conveyors. With Integrated Motion on EtherNet/IP™, you can place these drives on the same network as Kinetix® drives. A Dual-port EtherNet/IP™ Option Module supports ring, linear, and star topologies, as well as Device Level Ring (DLR) functionality for fault tolerant connectivity and high drive availability.
Name fault+Fault# : Power Loss #3
Description/Action : The DC bus voltage remained below the [Pwr Loss n Level] of nominal for longer than the time programmed in [Pwr Loss n Time].
Name fault+Fault# : UnderVoltage #4
Description/Action : If the bus voltage indicated in parameter DC Bus Volts falls below the value set in parameter UnderVltg Level an undervoltage condition exists.
Name fault+Fault# : OverVoltage #5
Description/Action : The DC bus voltage exceeded the maximum value. See parameter DC Bus Volts.
Name fault+Fault# : Motor Overload #7
Description/Action : An internal electronic overload trip has occurred.
Name fault+Fault# : Heatsink OvrTemp #8
Description/Action : The heatsink temperature has exceeded 100 % of the drive temperature.
Heatsink over temperature occurs between 115…120 °C. The exact value is stored in drive firmware.
See parameter Drive Temp Pct and/or parameter Drive Temp C.
Name fault+Fault# : Trnsistr OvrTemp #9
Description/Action : The output transistors have exceeded the maximum operating temperature.
See parameter IGBT Temp Pct and/or parameter IGBT Temp C.
If using the drive on a chiller plate, parameter PWM Frequency must be set to 2 kHz.
Name fault+Fault# : Ground Fault #13
Description/Action : A current path to earth ground greater than 25 % of drive rating has occurred.
Name fault+Fault# : Ground Warning #14
Description/Action : The ground current has exceeded the level set in parameter Ground Warn Lvl.
Name fault+Fault# : Load Loss #15
Description/Action : The output torque current is below the value programmed in parameter Load Loss Level for a time period greater than the time programmed in parameter Load Loss Time.
Name fault+Fault# : Input Phase Loss #17
Description/Action : The DC bus ripple has exceeded a preset level. Make these checks and adjustments in this order.
• Check input impedance balance.
• Increase the setting of P463 [InPhase Loss Lvl] to make the drive less sensitive.
• Tune the bus regulator or speed regulator to mitigate the effects of dynamic cyclic loads on DC bus ripple.
• Disable the fault by setting parameter InPhase LossActn to 0 “Ignore” and use an external phase loss detector such as a Bulletin 809S relay.
Name fault+Fault# : Output PhaseLoss #21
Description/Action : The current in one or more phases has been lost or remains below the threshold set in P445 [Out PhaseLossLvl] for 1 second. Decreasing the threshold makes the drive less sensitive to tripping. A deceased threshold is necessary when the motor is smaller than the drive rating.
Name fault+Fault# : Drive OverLoad #64
Description/Action : Parameter Drive OL Count has exceeded 50 % but is less than 100 %.
Parameter Drive OL Count has exceeded 100 %. Reduce the mechanical load on the drive.
Inverter fiber-optic connection is not detected on Frame 8 drive.
This fault can occur on power-up if the control detects that no inverter is detected via the fiber-optic communication on a Frame 8 drive.
Name fault+Fault# : AutoTune Aborted #80
Description/Action : The Autotune function was manually canceled or a fault occurred.
Name fault+Fault# : Parameter Chksum #100
Description/Action : The checksum read from the non-volatile storage does not match the
checksum calculated. The data is set to the default value.
Name fault+Fault# : HSFan Life #291
Description/Action : Predictive maintenance function has reached the event level. Perform maintenance.
Name fault+Fault# : InFan Life #292
Description/Action : Predictive maintenance function has reached the event level. Perform maintenance.
Name fault+Fault# : Program Error #906
Description/Action : Bad memory read.
Check grounding or replace the main control board.
Alarm name : : I1 Comm Loss
I2 Comm Loss
I3 Comm Loss
Description/Action : Indicates that the communication connection from the fiber optic interface board to the power layer interface board has been lost. Once the root cause of the communication fault has been resolved, power must be cycled or a drive reset must be initiated to clear this fault.
• Verify the status of the Fiber Loss pin segment of the power-layer interface board LED.
• Verify that the fiber optic cables are properly connected to the transceivers.
• Verify that the transceivers are properly seated in the ports.
• Verify that the fiber optic cable is not cracked or broken.
• Verify that power is applied to the fiber optic interface board and power layer interface board.
Alarm name : I1 HSFan Slow
I2 HSFan Slow
I3 HSFan Slow
Description/Action : The inverter heatsink fan is running below normal operating speed.
• Verify the actual fan speed in parameter In HSFan Speed
• Check for debris in the fan. If necessary, clean the fan and housing.
• Check for noise at the fan, indicating motor bearing failure.
• Verify that the fan power and feedback connections are not loose or disconnected.
• Replace the fan, if necessary.
Alarm name : I1 Bus Overvolt
I2 Bus Overvolt
I3 Bus Overvolt
Description/Action : The DC bus has exceeded the maximum value.
• Verify the correct voltage on the AC input line.
• Reduce the mechanical load and/or rate of deceleration.
• Compare the DC bus voltage displayed in parameter In DC Bus Volt, in parameter Cn DC Bus Volt, and with a meter using the DC+ and DCtest points at the top of the inverter. If the measurements do not match, the components that are used for DC bus voltage feedback sensing can be damaged or incorrect. Replace the power supply, power control, and power-layer interface circuit boards.
Alarm name : I1 Ground Fault
I2 Ground Fault
I3 Ground Fault
Description/Action : A current path to earth ground greater than 25 % of drive rating has occurred.
• Perform a Megger or surge test on a disconnected motor. Replace the motor, if necessary.
• Check the output phase current displayed in parameter In U Phase Curr, parameter In V Phase Curr, and parameter In W Phase Curr for an imbalance. Parameter In Gnd Current is the calculated (not measured) ground current based on the phase currents.
• If the ground fault happens immediately when the drive is started, view the values of the output phase current parameters (noted in the second bullet) when running the drive with a light load or perform a trending analysis.
• Reseat the rating plug and current transducer wiring harness.
Alarm name : I1 IGBT OvrTemp
I2 IGBT OvrTemp
I3 IGBT OvrTemp
Description/Action : An IGBT over temperature has been detected. This power layer interface board calculated this value based on the NTC temperature plus a rise based on recent currents through the inverter.
• Check the NTC temperature that is displayed in parameter In Heatsink Temp and verify that it is not near the limit. If this value is near the limit, check for cooling problems caused by a blocked or slow heatsink fan.
• Check the output phase current displayed in parameter In U Phase Curr, parameter In VPhase Curr, and parameter In W Phase Curr for an imbalance.
• Check for high-current operation at low speeds, since nearly all current goes through one IGBT in this case.
• Replace the power layer interface board.
Alarm name : I1 HS OvrTemp
I2 HS OvrTemp
I3 HS OvrTemp
Description/Action : A heatsink over temperature has occurred in inverter 1.
• Verify that the NTC is not disconnected or shorted.
• Check for cooling problems - the heatsink cooling fan is running slow, the enclosure filter or heatsink fins are dirty, or the ambient temperature is too high.
• Check the NTC resistance with a meter. If the resistance is correct, replace the power layer interface board.
