7.7 Start-up and stop control
The start-up and stop control of the inverter 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 inverter: 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.
