What causes current detection fault in Inovance MD380-5T5.5GB?
If your Inovance DC Drive displays a current detection fault, it could be due to a faulty HALL device or a faulty drive board. To resolve this, replace the faulty HALL device or the faulty drive board.
Why does Inovance MD380-5T5.5GB DC Drives have overcurrent during acceleration?
When an Inovance DC drive experiences overcurrent during acceleration, it may be due to a grounded or short-circuited output circuit, failure to perform motor auto-tuning, an excessively short acceleration time, an inappropriate manual torque boost or V/F curve, low voltage, starting a rotating motor, a sudden load during acceleration, or an undersized AC drive. To address this, eliminate external faults, perform motor auto-tuning, increase the acceleration time, adjust the manual torque boost or V/F curve, correct the voltage, use rotational speed tracking restart or wait for the motor to stop before starting, remove the added load, or select an AC drive with a higher power class.
What to do if Inovance DC Drives show overcurrent at constant speed?
If you observe overcurrent at constant speed in Inovance DC Drives, it could be caused by a grounded or short-circuited output circuit, failure to perform motor auto-tuning, low voltage, a sudden load during operation, or an AC drive model with insufficient power. To fix this, eliminate any external faults, perform motor auto-tuning, ensure the voltage is within the normal range, remove any added loads, or choose an AC drive with a higher power class.
Why does Inovance MD380-5T5.5GB DC Drives have overvoltage during deceleration?
If overvoltage occurs during deceleration in Inovance DC Drives, it could be due to high input voltage, an external force driving the motor, a deceleration time that is too short, or the absence of a braking unit and resistor. To solve this, adjust the voltage to the normal range, eliminate the external force or install a braking resistor, increase the deceleration time, or install the braking unit and braking resistor.
What to do if Inovance DC Drives show undervoltage?
If your Inovance DC drive shows undervoltage, it might be due to an instantaneous power failure, the input voltage being outside the allowable range, abnormal bus voltage, faulty rectifier bridge or buffer resistor, or a faulty drive or main control board. Try resetting the fault, adjusting the voltage to the normal range, or contacting Inovance or their agent for further assistance.
What causes contactor fault in Inovance MD380-5T5.5GB DC Drives?
If the Inovance DC drive shows a contactor fault, it may be due to a faulty drive board, power supply, or the contactor itself. To resolve this, replace the faulty drive board, power supply board, or the contactor.
What does AC drive hardware fault mean in Inovance MD380-5T5.5GB?
If your Inovance DC Drive displays an 'AC drive hardware fault', it indicates either an overvoltage or overcurrent condition. Address the issue based on the specific overvoltage or overcurrent troubleshooting steps.
What causes pulse-by-pulse current limit fault in Inovance MD380-5T5.5GB DC Drives?
If your Inovance DC Drive is experiencing a pulse-by-pulse current limit fault, it could be due to an excessively heavy load, a locked rotor on the motor, or an AC drive model with insufficient power. To fix this, reduce the load and check the motor and mechanical condition, or select an AC drive of higher power class.
How to resolve module overheat in Inovance MD380-5T5.5GB DC Drives?
If your Inovance DC Drive experiences a module overheat, it could be due to high ambient temperature, a blocked air filter, a damaged fan, a damaged thermally sensitive resistor, or a damaged inverter module. To solve this, lower the ambient temperature, clean the air filter, or replace the damaged fan, thermally sensitive resistor, or inverter module.
What causes power input phase loss in Inovance MD380-5T5.5GB DC Drives?
If your Inovance DC Drives show power input phase loss, it could be due to an abnormal three-phase power input, a faulty drive board, a faulty lightening board, or a faulty main control board. To address this, eliminate external faults or contact Inovance or their agent.
