What causes control power supply fault in Sako V780 Inverter?
If your Sako Inverter experiences a control power supply fault, it is likely because the input voltage is not within the allowable range. To resolve this, adjust the input voltage to the allowable range.
Why Sako Inverter shows power output phase loss?
If your Sako Inverter experiences a power output phase loss, consider the following: * The cable connecting the AC drive and the motor is faulty: Eliminate external faults. * The AC drive's three-phase outputs are unbalanced when the motor is running: Check whether the motor three-phase winding is normal. If the issue persists, it may be due to a faulty drive board or IGBT, in which case you should contact technical support.
What to do when Sako Inverter has power input phase loss?
If your Sako Inverter experiences a power input phase loss, consider the following possible causes: * The three-phase power input is abnormal: Eliminate external faults. If the issue persists, it may be due to a faulty drive board, lightening board, or main control board, in which case you should contact technical support.
How to troubleshoot Err01 protection on Sako V780 Inverter?
If your Sako Inverter displays the Err01 protection error, it indicates a problem with the output circuit. This could be due to several reasons: * The output circuit is grounded or short-circuited: Eliminate any external faults. * The motor's connecting cable is too long: Install a reactor or an output filter. * The IGBT is overheating: Check the air filter and cooling fan. * Internal connections are loose: Ensure all cables are properly connected. If the issue persists, it may be due to a faulty main control board, drive board, or AC drive IGBT, in which case you should contact technical support.
Why Sako V780 Inverter has no display at power-on?
If your Sako Inverter is not displaying anything at power-on, check the following: * Ensure there is a power supply to the AC drive and that the power input is sufficient: Check the power supply. * The power supply of the switch on the drive board of the AC drive may be faulty: Check the bus voltage. * The rectifier bridge may be damaged: Re-connect the 8-core and 28-core cables. If these steps don't resolve the issue, it could be due to inverter buffer resistance damage, a faulty control board, or a faulty operation panel, in which case you should contact technical support.
What causes overvoltage at constant speed on Sako Inverter?
If your Sako Inverter experiences overvoltage at a constant speed, it could be due to: * The input voltage being too high: Adjust the voltage to the normal range. * An external force driving the motor during deceleration: Cancel the external force or install the braking resistor.
Why does my Sako V780 Inverter show motor overload?
If your Sako Inverter displays a motor overload, it could be due to several reasons: * P9-01 is set improperly: Set P9-01 correctly. * The load is too heavy or locked rotor occurs on the motor: Reduce the load and check the motor and the mechanical condition. * The AC drive model is of too small power class: Select an AC drive of higher power class.
What to do if Sako Inverter shows AC drive overload?
If your Sako Inverter is experiencing AC drive overload, it could be due to: * The load being too heavy or locked rotor occurring on the motor: Reduce the load and check the motor and mechanical condition. * The AC drive model being of too small power class: Select an AC drive of higher power class.
What causes undervoltage in Sako Inverter?
If your Sako Inverter is showing an undervoltage error, here are some things to consider: * There may be an instantaneous power failure on the input power supply: Reset the fault. * The AC drive's input voltage may not be within the allowable range: Adjust the voltage to the normal range. If these steps don't resolve the issue, it could be due to an abnormal bus voltage, faulty rectifier bridge and buffer resistor, or a faulty drive board, in which case you should contact technical support.
How to troubleshoot communication fault on Sako V780?
If your Sako Inverter displays a communication fault, consider the following potential causes: * The host computer is in an abnormal state: Check the cabling of the host computer. * The communication cable is faulty: Check the communication cabling. * The communication parameters in group FD are set improperly: Set the communication parameters properly.
