Brief description Movement takes place to the specified target position when the setpoint
position is selected and start is set. It is possible to move an individual
axis (PO3 1 ... 12) or the entire axis system (PO3 = 99).
Prerequisite • Operating mode is selected
• Drive is enabled
Functional
description The positioning sequence is started using bit PO1:8
Start.
The user specifies the absolute target position via
fieldbus.
Speed and ramp times are adopted from the
specified process data words and compared to the
limitations from the startup.
The position specification can be changed during
ongoing operation. When the drive reaches the
target position, it stops with position control and
sends back the “In position” signal by setting bit
PO1:3.
If software limit switches are defined, the target
position will be checked cyclically for plausibility. If a
position is specified, which lies outside the software
limit switch range, a fault message will be issued
and the ongoing movement will be stopped. This
monitoring function can be deactivated with the input
bit Disable SWLS.
