6.5.7 Start/stop control

The start/stop control of the VFD involves three states: start after a running command is given at
power-on; start after power-off restart is effective; start after automatic fault reset. The three start/stop
control states are described in the following.
There are three start modes for the VFD, which are start at starting frequency, start after DC braking,
and start after speed tracking. You can select the proper start mode based on actual conditions.
For large-inertia load, especially in cases where reversal may occur, you can choose to start after DC
braking or start after speed tracking.
Note: It is recommended to drive SMs in direct start mode.
