Why is my Vaidnor DC Drives showing AC drive overload?
If your Vaidnor DC drive is reporting an AC drive overload, it could be due to a load that is too heavy, or locked-rotor occurring on the motor, so reduce the load and check the motor and mechanical conditions. Also, the AC drive model might be of too small power class, so select an AC drive of a higher power class.
What causes overvoltage during acceleration in Vaidnor VDF730 DC Drives?
If your Vaidnor DC drive is experiencing overvoltage during acceleration, it could be due to several reasons. The input voltage might be too high, so adjust the voltage to the normal range. An external force might be driving the motor during acceleration; cancel the external force or install a braking resistor. The acceleration time might be too short, so increase it. 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 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 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.
