Figure 6.6.1.1: Accel, decel and Quick stop
Acc delta speed Has the same units as the ramp reference value and is based on the factor function.
Acc delta time Is defined in seconds. If “0 s” is entered,the ramp output directly follows the reference
value.
Dec delta speed Has the same units as the ramp reference value and is based on the factor function.
Dec delta time Is defined in seconds. If “0s” is entered, the ramp output directly follows the reference
value.
Qstp delta speed Has the same dimension as the ramp reference value and is based on the factor function.
Qstp delta time Is defined in seconds. If “0 s” is entered, the ramp output follows the reference value.
Quick stop Activates the Quick stop ramp
The acceleration of the drive is defined as a quotient of the Acc delta speed and Acc delta time parameters (see Figure
6.6.1.1). As for the four quadrant converters (6KDV3 ... Q4...) it is the same for both directions of rotation.
