What to do if INVT Inverter shows current detection fault?
If the INVT Inverter displays a current detection fault, you can: * Check the connector and re-plug in case of poor contact of the connector of control board. * Replace the hall component if it is damaged. * Replace the main control board if exception occurred to amplification circuit.
What causes rectifier module overheating in INVT Goodrive300-21?
Rectifier module overheating in your INVT Inverter can be caused by: * Blocked air duct or damaged fan: Ventilate the air duct or replace the fan. * High ambient temperature: Lower the ambient temperature. * Long-time overload running.
What to do if INVT Goodrive300-21 reports motor autotuning fault?
If the INVT Inverter reports a motor autotuning fault, consider the following: * Change the inverter model if the motor capacity does not match the inverter capacity. * Set proper motor type and nameplate parameters if the motor parameter is set improperly. * Empty the motor load and carry out autotuning again if the parameters gained from autotuning deviate sharply from the standard parameters. * Check the motor wiring and parameter setup, and check whether the upper limit frequency is larger than 2/3 of the rated frequency if autotuning timeout.
How to troubleshoot phase loss on input side of INVT Inverter?
To troubleshoot phase loss on the input side of your INVT Inverter: * Check the input power if phase loss or violent fluctuation occurred on input R, S, T. * Check the installation wiring.
What to do if INVT Inverter shows bus undervoltage fault?
If the INVT Inverter shows a bus undervoltage fault, check the grid input power because the voltage of the grid may be too low.
What to do if INVT Inverter has RS485 communication fault?
If your INVT Inverter is experiencing an RS485 communication fault, consider the following: * Ensure the baud rate is set properly. * Check the wiring of communication interfaces for any faults. * Verify the communication address is set correctly. * If communication suffers from strong interference, replace or change the wiring to enhance the anti-interference capacity.
Why INVT Inverter shows motor overload?
The INVT Inverter might show a motor overload due to several reasons: * If the grid voltage is too low, check the grid voltage. * If the motor rated current is set incorrectly, reset the motor rated current. * If the motor stall occurs or the load transient is too large, check the load and adjust the torque boost quantity.
What to do if INVT Goodrive300-21 Inverter shows overvoltage during acceleration?
If the INVT Inverter shows overvoltage during acceleration, it could be due to the following reasons: * Check the input power if there is an exception occurred to input voltage. * Check whether load DEC time is too short, or the motor starts during rotating, or additional dynamic brake components is required because of large energy feedback.
