Q : When large motors move together, why the VFD stops during operation?
A: When the motor is started, the starting current corresponding to the capacity will flow, and the transformer on the stator side of the motor will produce a voltage drop. When the motor capacity is large, the voltage drop will also have a great impact. The VFD connected to the same transformer will make a judgment of undervoltage or instantaneous stop, so sometimes the protection function acts, resulting in stop.
