The Novakon Pulsars have a servo spindle motor fed by a Maxsine EP1 servo drive. There is a cable running from the servo motor encoder back to the servo drive. This encoder data is sent to the Novakon breakout board so as to enable rigid tapping.

The Pulsar manual shows a “spindle sensor selector” jumper on the Novakon Pulsar BOB Rev 0 that selects between “magnetic spindle sensor” and “spindle server encoder” and applies that to Input Pin 12.

Has anyone been able to use this servo encoder data to display actual spindle rpm’s on the controller screen?

Asking for a friend.
