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 does user-defined fault 2 mean for Inovance MD380S0.4GB?
If your Inovance DC Drive reports a 'User-defined fault 2', it means the user-defined fault 2 signal is being input via DI or virtual I/O. To resolve this, reset the operation.
What causes power input phase loss in Inovance MD380S0.4GB?
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 does PID feedback lost during running mean for Inovance MD380S0.4GB?
If your Inovance DC Drive shows 'PID feedback lost during running', it indicates that the PID feedback is lower than the setting of FA-26. Check the PID feedback signal or set FA-26 to a proper value.
What does load becoming 0 mean for Inovance DC Drives?
If your Inovance DC Drive displays 'Load becoming 0', it means the AC drive running current is lower than the value set in F9-64. Check if the load is disconnected or verify that the settings of F9-64 and F9-65 are correct.
What causes initial position fault in Inovance DC Drives?
If your Inovance DC Drive shows an initial position fault, it means the motor parameters are not set based on the actual situation. Check that the motor parameters are set correctly and verify that the setting of rated current is not too small.
Why does Inovance 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 MD380S0.4GB 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 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 MD380S0.4GB 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.
