4.4.2.3 Acceleration and Deceleration
For parameters Acceleration 1204 and Deceleration 1205, the values for the mo-
tion to the target position are adjusted.
Via the ramp rise time, a non-linear acceleration and deceleration (S-curve) can be
obtained, and the load during acceleration and deceleration of the drive can be re-
duced, e.g. in order to limit jerking. The factory setting of 0 ms causes a linear
ramp.

4.4.2.4 Automatic sequence of motion blocks (next motion
block)
In parameter configuration Operation Mode 1221 = 1xx (e.g. 101, 111, “Sequence
Mode”), the positioning function enables an automatic sequence of motion blocks,
i.e. when the target position is reached, the next target position is selected. The
sequence control can be time-based (e.g. after a certain time has elapsed) or event-
oriented (e.g. via digital inputs or logic modules).
The next motion block starts:
− After expiry of a delay time:
After expiry of
Delay 1212 the motion block from Delay: Next Motion Block
1213 starts.
− After attaining a target position:
Event 1 1214 starts the motion block from Event 1: Next Motion Block 1215.
Event 2 1216 starts the motion block from Event 2: Next Motion Block 1217.
− After interruption of a running motion block:
Interrupt-Event 1 1260 starts the motion block from Int.-Event 1: Next Motion
Block
1262.
Interrupt-Event 2 1263 starts the motion block from Int.-Event 2: Next Motion
Block
1265.
In that way logic-specific branches in the sequences can be parameterized.
In the case of a relative positioning operation, the motion block can also be repeated
via
No. of Repetitions 1211.
