AC drives move into servo territory with option card

A synchronising and positioning option card for the VLT5000 AC drives from Danfoss is designed to give them the flexibility and accuracy of servo drives.

Each of the new cards contains a positioning controller which can perform relative or absolute positioning on one axis and a synchronising controller which controls two axes – this is extendible to 32 axes using a virtual master function and multiple controllers.

In addition to the synchronising and positioning functions, the card can also perform as a PLC: computing arithmetical operations, determining the logical gating of inputs, setting outputs, and running comparisons, loops and jumps.

The same card can be used on any VLT5000 drive, from 0.75 to 200kW.
