DC braking (Setting : 15)
OFF Normal
operation
ON
Applies DC injection braking if the inverter is stopped.
• This function is used to prevent the motor from rotating due to inertia
or external forces at stop.
• Inputting a run command or jog command (jog, clockwise jog, or
counterclockwise jog) clears the DC injection braking causing the
motor to start.

Speed search command 2 (Setting :17)
OFF Normal
operation.
ON
Starts a speed search from the pre-defined frequency.
• Only one of the search functions can be selected.
• When switching the operation from a commercial power supply and the
