Introduction

The Positioning Controller is an application option for the VLT 5000 and VLT 5000 Flux Series. It is
based on the SyncPos option card.
The positioning controller can be used in a wide range of applications where a frequency converter is
used for positioning. The controller holds information of up to 32 (64 in field bus mode) fixed positions.
Relative positions can be added to each other by triggering a new relative positioning command when
the controller is already executing a relative positioning command.
Full field bus support is now included meaning starting and stopping etc can be done via bus.
In field bus mode a "quickbus" mode is introduced to enable writing a target position directly. Hence an
unlimited number of positions can be reached.
Positions are defined either relative to a fixed home position (absolute positions) or relative to other
positions, or relative to a movable "touch probe" sensor.
An advanced mechanical brake controller is included. It is strongly advised to use this brake function
as suppose to the VLT mechanical brake handler.
If absolute encoders must be used for positioning feedback in conjunction with VLT 5000 Flux this is
now possible. Encoder input MK 3B can be programmed as option feedback input allowing the
feedback encoder input MK 3D to be used for VLT 5000 Flux.
The encoder(s) connected can now hardware wise be monitored for open or short-circuits.
Last but not least VLT manual run mode is introduced. It is selected via parameter 711.
