I have an application where I will be using a Yaskawa SGDH servo drive with a SGMCS motor. The motor has an absolute encoder that goes back to the drive. I want this absolute position to go back to my RMC70 motion control. Here was the suggestion from Yaskawa
I don't see why this would not work. Has anyone done this type of thing before?
Instead of using the MA axis module with the Delta Computer controller, he would use the QA axis module.
We would hook the Sigma II amplifier up to the controller, just as if we were going to control the drive incrementally.
The SGMCS motor is a 20bit, single turn absolute encoder, when used as an absolute, with send quadrature encoder pulse stream out of the drive to the controller, before allowing the servo enable signal.
This is activated by providing a 5V TTL signal to the drive from the controller, letting the drive know that it is ready to receive the pulse stream.
The is a cost effective way to enable the use of absolute encoders, without the added cost of secondary SSI encoders, or the control cards (MA)
