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.
