Figure 6.17.4.1: Acceleration and deceleration
Qstp delta time Is defined in seconds. If “0 s” is entered, the ramp output follows the reference value
directly.
Quick stop Activates the Quick stop ramp to stop the Drive.
The acceleration of the drive is defined as a quotient of the Acc delta speed and Acc delta time parameters. It
is the same for both rotation directions of the motor.
The deceleration of the drive is defined as a quotient of the Dec delta speed and Dec delta time parameters. It
is the same for both rotation directions of the motor.
The Quick stop function provides a second deceleration ramp for braking the drive to halt in the event of an
emergency. The deceleration of the drive using the Quick stop function is defined as a quotient of the Qstp delta
speed and Qstp delta time. It is the same for both rotation directions of the motor. This function is only available
via the serial interface or BUS.

Face value fact
[54] Face value num
[53] Face value den
Dimension fact
[50] Dim factor num
[51] Dim factor den
[52] Dim factor text
The factor function contains two factors, the Dimension factor and Face value factor. They are both expressed
as fraction numbers.
The dimension factor enables the drive speed to be defined in a machine-related dimension, e.g. kg/h or m/min.
Further information and examples are given in the section on the Configuration menu.
