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'.
