How to fix phase sequence fault in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive displays a phase sequence fault, it means the phase sequence on the power input side is negative. To correct this, swap any two of the power input cables.
Why is there overvoltage at acceleration in INVT Goodrive300-01A?
If your INVT DC Drive is experiencing overvoltage during acceleration, the input voltage might be abnormal, so check the input power. Alternatively, there might be large energy feedback. In this case, verify if the deceleration time of the load is too short or if the motor starts during rotation. Installing dynamic brake units might also be necessary.
How to fix inverter unit U phase protection in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive displays an inverter unit U phase protection error, it could be due to several reasons. The acceleration might be too fast; try increasing the acceleration time. There could be internal damage to the IGBT of that phase, requiring a power unit replacement. Improperly connected drive wires could also be the cause, so check the wiring. Finally, strong interference from peripheral equipment might be the culprit; investigate and eliminate any interference sources.
Why am I getting a bus undervoltage fault on my INVT Goodrive300-01A DC Drives?
If your INVT DC Drive shows a bus undervoltage fault, it is likely that the grid voltage is too low. Check the grid input power to ensure it is within the appropriate range.
What causes motor overload in INVT Goodrive300-01A?
If your INVT DC Drive indicates a motor overload, it could be due to several reasons. The grid voltage might be too low, so check the grid voltage. The rated motor current might be set improperly; reset it to the correct value. Alternatively, the motor might be stalling or experiencing load transients. In this case, check the load and adjust the torque boost quantity.
What causes speed deviation fault in INVT Goodrive300-01A?
If your INVT DC Drive is showing a speed deviation fault, it could be because the load is too heavy or there is a stall. Check the load to ensure it is normal, and increase the detection time.
How to fix parameter download error on INVT DC Drives?
If your INVT DC Drive is experiencing a parameter download error, it could be due to a poorly contacted or disconnected keypad line. Check the environment and rule out the interference source. The keypad wire might be too long or suffering from strong interference; replace the hardware and ask for maintenance service. Alternatively, the storage data in the keypad could be wrong, so re-copy the data in the keypad.
What does to-ground short mean on INVT Goodrive300-01A?
If your INVT DC Drive indicates a 'To-ground short,' it means the VFD output is short-circuited to ground. Check whether the motor wiring is normal and if the motor is short-circuited to ground.
What causes current detection fault in INVT DC Drives?
If your INVT DC Drive shows a current detection fault, it could be due to a poor contact of the controller board connector, so check the connector and re-plug the wires. The hall components might be damaged, requiring a replacement. Alternatively, the amplifying circuit could be abnormal, necessitating replacement of the main control board.
What does external fault mean on INVT Goodrive300-01A?
If your INVT DC Drive displays an external fault, it means the S external fault input terminal is active. Check the external equipment input to resolve this issue.
