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 to do if Inovance MD380-5T5.5GB show inverter unit protection?
If an Inovance DC Drive experiences inverter unit protection, it could be due to several reasons: * The output circuit is grounded or short-circuited. * The motor cable is too long. * The module is overheating. * Internal connections are loose. * The main control board, drive board, or inverter module is faulty. To resolve this, eliminate external faults, install a reactor or output filter, check the air filter and cooling fan, properly connect all cables, or contact Inovance or their agent.
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.
What causes overvoltage during acceleration in Inovance MD380-5T5.5GB?
If you're experiencing overvoltage during acceleration with your Inovance DC Drives, it could be due to an input voltage that's too high, an external force driving the motor, an acceleration time that's too short, or the absence of a braking unit and braking resistor. To fix this, adjust the voltage to the normal range, cancel the external force or install a braking resistor, increase the acceleration time, or install the braking unit and braking resistor.
How to troubleshoot motor overload in Inovance DC Drives?
If your Inovance DC drive shows motor overload, it might be due to improper F9-01 settings, an excessively heavy load, a locked rotor, or an AC drive model of insufficient power. To resolve this, ensure F9-01 is set correctly, reduce the load, inspect the motor and mechanical components, or select an AC drive with a higher power rating.
How to fix AC drive overload in Inovance MD380-5T5.5GB?
If your Inovance DC drive is experiencing AC drive overload, it could be because the load is too heavy, the motor is locked, or the AC drive's power class is too small. Try reducing the load, checking the motor and mechanical condition, or selecting an AC drive with a higher power class.
Why does Inovance MD380-5T5.5GB DC Drives have overcurrent during deceleration?
Overcurrent during deceleration in Inovance DC Drives can occur if the output circuit is grounded or short-circuited, motor auto-tuning hasn't been performed, the deceleration time is too short, the voltage is too low, a sudden load is added, or the braking unit and resistor are missing. Solutions include eliminating external faults, performing motor auto-tuning, increasing the deceleration time, adjusting the voltage, removing the added load, or installing the braking unit and 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.
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 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.
