5.5.7 Start/stop control
The start/stop control of the VFD is divided into three states: start after running command at power-on;
start after restart-at-power-cut function is effective; start after automatic fault reset. Descriptions for
these three start/stop control states are presented below.
There are three start modes for the VFD, which are start at starting frequency, start after DC brake,
and start after speed-tracking. You can select the proper start mode based on field conditions.
For large-inertia load, especially in cases where reversal may occur, you can choose to start after DC
braking or start after speed-racking.
Note: It is recommended to drive synchronous motors in direct start mode.
