I am getting close to the end of my pre-install planning. I only have a few things left before I do the bench test and the final install. I have the Mitsubishi MDS-A-SPJA-75RT spindle drive, and an encoder 1:1 mounted to the spindle. The Mitsubishi spindle drive has encoder feed back from the motor. Would I use the MPU11 DB9 ports for the direct spindle encoder, or how would the spindle encoder be hooked up to the GPOI4D/MPU11 boards?
I attached the corresponding pages from the Mitsubishi manual for reference.

Re: GPIO4D/MPU11 spindle Encoder hook up
It appears that your controller has pass-through capability. I would connect the encoder to the spindle drive, then connect the drive to the MPU11. That way the drive can use the encoder for speed control and stop orientation, and the MPU11 get the encoder signal as well for rigid tapping and feed per rev movements.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.
