Positioning and speed control

[ABlearner 2]

Hello Guys.

Is it possible to use an fr-a840 to use in the same time positioning control and also in speed control mode ?

In the moment the vfd is in speed control mode. But now i also have to need to stop the conveyor in certain position. It will be a new feature. If its not possible, do i need a hsc ? 

The speed of the conveyor is 20 m/min and the accuracy should be within 3 mm. 

Could anybody help me with this. 

Thanks ahead.

But a lot depends on the equipment you have available...

What PLC? Is there positionnig card installed on the A840 and motor feedback (encoder)?
