What to do if MCU receives wrong data from DSP on Veikong Inverter?
If your Veikong Inverter's MCU receives wrong data from DSP, ensure proper cable layout to avoid external disturbance. If the issue persists, it may indicate an internal fault, and you should contact service.
What to do if Veikong VFD700-PV-40T00075 shows over voltage?
If your Veikong Inverter is showing an over voltage error, it could be due to several reasons. First, ensure that the supply voltage is within the specified range. A sudden load change can also cause this issue, so avoid making abrupt changes to the load. If the deceleration rate is too short, increase it and consider adding a suitable brake resistor. If these steps don't resolve the problem, it may indicate an internal fault, and you should contact service.
Why is Veikong VFD700-PV-40T00075 showing under voltage?
If your Veikong Inverter is showing an under voltage error, begin by checking the power supply to ensure it is adequate. If the error occurs during drive power off, this is normal and won't be logged in the trip tracking. If the problem persists and isn't related to power off, there may be an internal fault, and you should contact service.
How to fix motor overload on Veikong VFD700-PV-40T00075?
If your Veikong Inverter indicates a motor overload, there are a few things to investigate. First, ensure that the V/F settings are correctly configured. Also, check the power supply and cabling to make sure the supply voltage is adequate. If the motor axis is stocked or the load changing is too big, check the load. Finally, verify that the motor overload protection factor (P12.12) is correctly set.
Why is there over current during power up of Veikong VFD700-PV-40T00075 Inverter?
If your Veikong Inverter experiences over current during power up, check the output cabling and motor for earth faults. If no faults are found, contact service.
What causes user 24V overload on Veikong VFD700-PV-40T00075?
If your Veikong Inverter is showing a User 24V overload error, check if there is a shortage on the output of DO and 24V, as the output current of 24V and DO1 may be over 100mA.
How to troubleshoot control fan fault on Veikong VFD700-PV-40T00075?
If your Veikong Inverter (30kW and above) is reporting a control fan fault, check the fan blades for any rotation issues. Also, check the fan wiring to ensure it is correctly connected. If problems persist, contact service.
What to do if AI1 input is loosing on Veikong VFD700-PV-40T00075 Inverter?
If your Veikong Inverter indicates that the AI1 input is loosing, check the AI1 input to ensure the input current is not smaller than 3mA.
How to fix auto-tune wrong error on Veikong VFD700-PV-40T00075 Inverter?
If the auto-tune process fails on your Veikong Inverter, it could be due to a few reasons. The drive size may not match the motor power size, in which case you should change the drive. Ensure that you have correctly set the motor data according to the motor nameplate. Also, make sure you allow the auto-tune process to finish completely without stopping the drive.
