NettetStall protection Stall protection is generally for synchronous motors. For induction motors, the stall during acceleration is necessarily over current, and VFD can protect the motor by over current and overload protection. Stall during deceleration can be avoided by setting a safe deceleration time during commissioning. Buying an ATO VFD to ... NettetHowever, disabling the outputs when a stall is detected can protect the motor and the system from excess mechanical forces and electrical currents caused by stalling. In the waveform, you can observe how the initial inrush current was ignored by the MCU. This is because the stall delay programmed is longer than the inrush time.

Most users of electric machines feel that the safe stall time must be longer than the acceleration time in order to safely protect the unit against thermal damage. It is also felt that the longer stall time …
