118.11 Speed
The positioning speed describes the maximum permitted adjusting speed of the position-
ing module output during a positioning task.
It may be changed through Parameter Z121.7– Feedrate override during ongoing posi-
tioning.
Exception: The feedrate override no longer works during braking.
118.12 Acceleration
The parameter specifies the maximum acceleration for the positioning task.
118.13 Deceleration
The parameter specifies the maximum deceleration for the positioning task.
118.14 Jerk
This parameter is used to adjust the maximum jerk (change of acceleration) for the S-
curve profile (jerk limited positioning).
The parameter has no effect with other speed profiles.
118.15 Smoothing time
A PT
1
element has been implemented to achieve a rounding of ramp corners in the trap-
ezoidal profile (Parameter Z118.2– Mode bit 2 and 3 = 00). The time constant of the PT
1
element can be adjusted using this parameter.
Looping is deactivated with a setting of 0 ms.
The profile algorithm prevents the effect of an "Online" loop change (during an ongoing
positioning set). This prevents undesired occurrences or overrunning of a target position.
118.16 Relative target position
In this parameter, the relative target position with applied leading signs is set for the po-
sitioning set 0 (Z118.6– Record number actual = 0). This parameter works in target
modes: 4, 7, 9 and 12.
