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.
How to fix encoder reversal on INVT Goodrive300-01A DC Drives?
If your INVT DC Drive is showing encoder reversal, it means the encoder speed signal is contrary to the motor running direction. Reset P20.02 encoder direction to resolve this.
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.
What to do if air filter is blocked in INVT Goodrive300-01A?
If the air filter is blocked in your INVT DC Drive, it means the air filter is abnormal. Check the air filter after stopping the drive.
What to do if touch screen communication is interrupted in INVT DC Drives?
If the touch screen communication is interrupted on your INVT DC Drive, it is likely that the 485 communication port is disconnected. Check whether the communication line is loosened.
What causes temperature pre-alarm in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive is showing a temperature pre-alarm, it could be because the actual temperature detected by PT1 is higher than the pre-alarm temperature set by P18.19. Check whether the fan control parameters are set correctly and whether the fan operates normally.
What causes VFD overload in INVT Goodrive300-01A DC Drives?
If your INVT DC Drive is showing a VFD overload, it could be because the acceleration is too fast, so increase the acceleration time. Another cause could be that the motor was restarted too soon. To resolve this, restart the motor after it has completely stopped.
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.
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.
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.
