If your INVT DC Drives display 'Brake unit fault', it could be due to a braking circuit failure or a damaged brake tube. Inspect the braking unit and replace the braking tube if necessary. Another potential cause is too low resistance of the externally connected braking resistor; in that case, increase the braking resistance.
What to do if there is over-current during acceleration in INVT DC Drives?
To address over-current during acceleration with your INVT DC Drives, first, check for any short-circuits or ground faults at the inverter output. Inspect the motor for damage, worn insulation, or cable issues. If the hardware is fine, increase the Acc/Dec time or choose a higher capacity inverter. Also, review and adjust the V/F curve settings and check the load.
How to troubleshoot communication fault in INVT DC Drives?
If the INVT DC Drives show a communication fault, it may be due to an improper baud rate setting. In this case, set the proper baud rate. It could also be due to receiving wrong data, so check communication devices and signals. Another potential cause is the communication being interrupted for a long time.
What causes output phase failure in INVT CHV DC Drives?
If the INVT DC Drives show an output phase failure, check the wiring and installation. This issue can arise from a broken wire in the output cable, a broken wire in the motor winding, or loose output terminals.
What to do if DC bus under-voltage occurs in INVT CHV?
If the INVT DC Drives show a DC bus Under-voltage error, inspect the input power supply and wiring. This problem can arise from an open phase in the power supply, a momentary power loss, loose wiring terminals for the input power supply, or large voltage fluctuations in the power supply. Also inspect external equipment.
What causes input phase failure in INVT CHV?
If your INVT DC Drives has input phase failure, check the wiring, installation, and power supply. The issue may stem from an open-phase in the power supply, a momentary power loss, loose wiring terminals for the input power supply, significant voltage fluctuations, or poor voltage balance between phases.
What causes rectify overheat in INVT CHV DC Drives?
If your INVT DC Drives display 'Rectify overheat', several factors could be responsible. The ambient temperature may be too high, or there could be a nearby heat source. Consider installing a cooling unit or removing the heat source. Check if the inverter's cooling fans have stopped or are damaged; if so, replace the cooling fan. Obstruction of the ventilation channel can also cause overheating; clear the channel. Lastly, a high carrier frequency can contribute to this issue; decrease the carrier frequency.
How to troubleshoot IGBT Ph-U fault in INVT DC Drives?
If the INVT DC Drives show an IGBT Ph-U fault, it could be due to several reasons. The acceleration or deceleration time might be too short, so try increasing it. There might be a malfunction caused by interference, so inspect external equipment and eliminate any interference. Also, ensure that grounding is properly set up. If the issue persists, it could be an IGBT module fault, and you should ask for support.
What to do if there is a motor overload in INVT CHV DC Drives?
If the INVT DC Drives motor is experiencing an overload, consider these potential causes. The motor might be driving a heavy load at low speed for an extended period; if so, select a variable frequency motor. An improper V/F curve could also be the cause; check and adjust the V/F curve. Verify the motor’s overload protection threshold (PB.03) and adjust if necessary. Finally, check the load for any sudden changes.
Why does over-voltage occur during acceleration in INVT CHV DC Drives?
If your INVT DC Drives experience 'Over-voltage when acceleration', the deceleration time might be too short, causing excessive regenerative energy from the motor. Try increasing the deceleration time or connecting a braking resistor. Additionally, the input voltage may be too high; decrease it to stay within the specified limits.
