7.7 Start-up and stop control
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. Below is the detailed instruction for three startings.
There are three starting methods for the VFD: start from the starting frequency directly, start after the
AC braking 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 braking and then starting after rotation speed tracking.
Note: it is recommended to use the direct starting to drive synchronous motor.
