Marius,
You need to see what kind of encoder the Yaskawa motor has on it. I recall
many of them were serial w/ a proprietary Yaskawa protocol, which would
make it hard to run the encoder directly back to the mesa.
Possibly, the servo pack has an 'encoder out' feature that you could run
back to the mesa. Sometimes those encoder out features are standard
quadrature A, B, Z outputs... That would work well.
Yes, the slightly older Servo Pack drives I worked with all
had this feature. they converted the proprietary
Yaskawa encoder signals to industry-compatible quadrature
plus index signals in the drive.
