Hitachi S1 Series User Manual

S1 series standard inverter
-57-
5.5.6 Start/stop control
The start/stop control of the inverter is divided into three states: start after running command at
power-up; 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 inverter, which are start at starting frequency, start after DC brake,
and start after speed-tracking. Users can select the proper start mode based on field conditions.
For large-inertia load, especially in cases where reversal may occur, users can choose to start after
DC brake or start after speed-racking.
