The start-up and stop control of the VFD includes three states: start after the running command during normal powering on, start after the restarting function becomes valid during normal powering on and start after the automatic fault reset.
There are three starting modes for the VFD: start from the starting frequency directly, start after the AC brake and start after the rotation speed tracking. The user can select according to different situations to meet their needs.
For the load with big inertia, especially in the cases where the reverse rotation may occur, it is better to select starting after DC brake and then starting after rotation speed tracking.
Note: It is recommended to use the direct starting to drive synchronous motor.
1. The starting logic figure of starting after the running command during the normal powering on.
2. The starting logic figure of starting after the restarting function becomes valid during the normal powering on.
3. The starting logic figure of starting after the automatic fault reset.
