17-95 Offset Execution Distance
Default value: 0 AbsolutePositionUnit
Setup: All setups
Data type: Int32
This parameter is only available with software version 48.9X.
With the dynamic offset feature, it is possible to distribute execution of relative master offset and marker correction while synchronizing
over a specific distance instead of using Ramp 1 (parameter group 3-4* Ramp 1) and parameter 3-28 Master Offset Speed Ref. With this
feature, an offset execution profile is calculated based on:
Offset execution distance
l
Parameter 4-24 Max Speed
l
Actual master speed
l
Parameter 7-99 Min Ramp Time
l
The offset execution distance can be related to the distance traveled by the master or the follower, selected in parameter 17-96
Execution Distance Relation. The execution distance relation is automatically extended if required due to speed/ramp limitation. This
situation can be signaled in the fieldbus status word by selecting [22] Execution distance extended in parameter 8-13 Configurable
Status Word STW.
17-96 Execution Distance Relation
Default value: [0] Master related
Setup: All setups
Data type:
Uint8
This parameter is only available with software version 48.9X.
Select whether the value set in parameter 17-95 Offset Execution Distance is related to the distance traveled by the master or by the
follower.

Description
The drive selects the rotation direction that provides the shortest
route to the target position.
Move to the target position in the forward direction.
Move to the target position in the reverse direction.
The forward/reverse signal on a digital input or fieldbus
determines the rotation direction.
