Can you use the IO card AI3 A & B analog inputs on the Altivar ATV66 as a means of an opto isolater for their speed reference whos common is referenced to chassis ground.

Cannot use the IO card for this as the analog inputs are a summed iput and will fight each other if Ai3A is positive and Ai3B is referenceed to ground. Suggested third party isoltation module.
