What does "Err23" mean on Vaidnor VDF730 DC Drives at power-on?
If your Vaidnor DC drive displays 'Err23' at power-on, it could be because the motor or the motor output cable is short-circuited to the ground, so measure the insulation of the motor and the output cable with a megger. If the AC drive is damaged, contact the agent or vendor for technical support.
Why is my Vaidnor VDF730 DC Drives showing overvoltage during deceleration?
If your Vaidnor DC drive displays overvoltage during deceleration, it could be due to several factors. The input voltage might be too high, so adjust it to the normal range. Also, an external force might be driving the motor during deceleration; cancel this force or install a braking resistor. The deceleration time could be too short, so increase it. Finally, the braking unit and braking resistor might not be installed, so install them.
What to do if Vaidnor DC Drives has overcurrent during deceleration?
If your Vaidnor DC drive is showing an overcurrent during deceleration, there are several potential causes. The output circuit could be grounded or short-circuited, so you should eliminate any external faults. The deceleration time might be too short, so increase it. The voltage might be too low, so adjust it to the normal range. A sudden load could be added during deceleration, so remove the added load. Finally, the braking unit and braking resistor might not be installed, so install them.
Why is my Vaidnor DC Drives showing undervoltage?
If your Vaidnor DC drive is experiencing an undervoltage issue, it could be due to several reasons. There might be an instantaneous power failure on the input power supply, in which case you should reset the fault. The AC drive's input voltage might not be within the allowable range, so adjust the voltage to the normal range. If the bus voltage is abnormal, contact the agent or vendor.
What does “VDVN” mean on Vaidnor VDF730 display?
If your Vaidnor DC drive display is normal upon power-on, but "VDVN" is displayed after running and the AC drive stops immediately, it means the cooling fan is damaged or locked-rotor occurs. Replace the damaged fan.
What to do when accumulative running time reached on Vaidnor DC Drives?
If the accumulative running time has reached the setting value on your Vaidnor DC Drives, clear the record through the parameter initialization function.
What causes current detection fault in Vaidnor VDF730?
If your Vaidnor DC drive is experiencing a current detection fault, it could be because the HALL device is faulty, so replace the faulty HALL device. The drive board might be faulty, so replace the faulty drive board.
How to resolve motor auto-tuning fault in Vaidnor DC Drives?
If your Vaidnor DC drive is experiencing a motor auto-tuning fault, it could be because the motor parameters are not set according to the nameplate, so set the motor parameters according to the nameplate properly. The motor auto-tuning might time out, so check the cable connecting the AC drive and the motor.
What causes power output phase loss in Vaidnor DC Drives?
If your Vaidnor DC drive has a power output phase loss, it could be due to a faulty cable connecting the AC drive and the motor, so eliminate external faults. The AC drive's three-phase outputs might be unbalanced when the motor is running, so check whether the motor three-phase winding is normal. The drive board might be faulty, so contact the agent or vendor.
What causes module overheat in Vaidnor VDF730 DC Drives?
If your Vaidnor DC drive reports a module overheat, it could be due to several reasons. The ambient temperature might be too high, so lower the ambient temperature. The air filter might be blocked, so clean the air filter. The fan might be damaged, so replace the damaged fan. The thermally sensitive resistor of the module might be damaged, so replace the damaged thermally sensitive resistor. The inverter module might be damaged, so replace the inverter module.
