If the INVT DC Drive displays an autotuning fault, it could be due to improper settings of the motor's rated parameters or the autotuning process timing out. Set the rated parameters according to the motor nameplate and check the motor’s wiring.
Why is my INVT DC Drives showing inverter overload?
If your INVT DC Drive displays an inverter overload, it could be due to a heavy load, short acceleration/deceleration time, an unsuitable V/F curve, or the inverter's capacity being too small. Here's how to address it: * Increase the acceleration/deceleration time or choose an inverter with a larger capacity. * Check and adjust the V/F curve. * Consider selecting an inverter with a higher capacity.
How to fix IGBT Ph-U fault in INVT CHE100-1R5G-4 DC Drives?
If the INVT DC Drive shows an IGBT Ph-U fault, it could be due to several reasons: the acceleration/deceleration time being too short, a fault in the IGBT module itself, malfunction caused by interference, or improper grounding. To address this: * Increase the acceleration/deceleration time. * Inspect external equipment and eliminate any interference.
What causes over-voltage during acceleration in INVT DC Drives?
If the INVT DC Drive shows an over-voltage error during acceleration, it could be due to a short deceleration time causing excessive regenerative energy from the motor, or the input voltage being too high. To fix this, you can: * Increase the deceleration time or connect a braking resistor. * Decrease the input voltage to stay within the specified range.
Why is my INVT CHE100-1R5G-4 DC Drives showing motor overload?
If the INVT DC Drive indicates a motor overload, it may be because the motor is driving a heavy load at low speed for an extended period, the V/F curve is not properly set, the motor’s overload protection threshold (PB.01) is incorrect, or there is a sudden load change. To resolve this: * Select a variable frequency motor. * Check and adjust the V/F curve. * Check and adjust PB.01. * Check the load.
What causes DC bus Under-voltage in INVT CHE100-1R5G-4?
If the INVT DC Drive displays a DC bus under-voltage error, it could be due to 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. Inspect the input power supply or wiring.
How to troubleshoot brake unit fault in INVT CHE100-1R5G-4?
If the INVT DC Drive shows a brake unit fault, it could be due to braking circuit failure, a damaged brake tube, or too low resistance of the externally connected braking resistor. Inspect the braking unit and replace the braking tube if necessary. Increase the braking resistance.
What does EEPROM fault mean in INVT DC Drives?
If the INVT DC Drive displays an EEPROM fault, it indicates a read/write fault of control parameters. Press STOP/RESET to reset.
What causes current detection fault in INVT CHE100-1R5G-4?
If the INVT DC Drive displays a current detection fault, it could be due to loose wires or connectors on the control board, a damaged Hall sensor, or an abnormal amplifying circuit. Check the wiring.
How to troubleshoot communication fault in INVT CHE100-1R5G-4 DC Drives?
If the INVT DC Drive displays a communication fault, it may be due to an incorrect baud rate setting, receiving incorrect data, or a prolonged interruption in communication. To solve this, set the proper baud rate and check the communication devices and signals.
