The deceleration of the drive is defined as a quotient of the parameters Dec delta speed and Dec delta time (see Figure
6.6.1.1). As for the four quadrant converters (6KDV3 ... Q4...) it is the same for both directions of rotation.
The Quick Stop function provides the possibility of a second deceleration ramp for the emergency braking of
the drive. The ramp output in this case is not set to zero immediately but after a set time. The deceleration of
the drive via the Quick Stop function is defined as the quotient of the Qstp delta speed and Qstp delta time
parameters. As for the four quadrant converters (6KDV3 ... Q4...) it is the same for both directions of rotation.
This ramp is activated by the functions Fast stop (via terminals) and Quick stop.
