7.22.7.9 Motion profile shape
7.22.7.10 Jerk ratio
7.22.7.11 Downtime 1
Parameter Description
• S-rounding
• For an S-shaped motion profile, the acceleration is linearly shown and hidden. This acts as
jerk limitation. Recommended for winding drives.
• linear
• Linear motion profiles have no jerk limitation. The maximum values of torque and speed
are reached simultaneously.
 Traction-controlled winding drive ( 210)
Parameter Description
Jerk ratio for the acceleration time and deceleration time.
• An S-shaped acceleration/deceleration consists of three sections:
• Showing the acceleration/deceleration
• Linear acceleration/deceleration
• Hiding the acceleration/deceleration
• The value defines the share of the two sections 'Showing' and 'Hiding'.
