PWM control of ANILAM SA411C VFD

Hi,

We are currently in the process of fitting a MASSO HTG5A1S to an ANILAM 6000i CNC machine.

Going through the masso site documentation did not reveal any answers.

The machine has 4 axis and a spindle drive. each one is controlled by PWM, there are a set of these terminals for each drive so 5 sets all up. Each set is like this:

PWM U1

0V U1

PWM U2

0V U2

PWM U3

0V U3

From my view it appears that the old control method was controlling each phase on each drive individually with PWM.

I am wondering if you may have come across a way of making this work with the masso or if there are any wiring suggestions for this layout. Much appreciated!

Thanks for the document, and its not a very fun document to read. I does look like it uses PWM signals but the document does not have any information about PWM timing or any other detailed information.

It does look like PWM signals are needed but will be good to have some more proper information before we can check everything.
