ISO1432: SIN COS Encoder Signals

Brian Wang0928

Part Number: ISO1432
Other Parts Discussed in Thread: UA9638, ISO7720,

My customer would like to use ISO1432 to replace the ISO7720+UA9638 and TLP2366(Opto Coupler) on Motor Encoder application. Please find here for configurations between CNC controller and Servo Drive.

Is there any side effect? Or any advice?

Hi Brian,

Thank you for posting to E2E!

Is our customer looking to operate the servo drives using RS-485? Can you share a part number for the Servo Drives?

Using ISO1432 may require additional hardware changes. Please allow me to confirm this alternative is suitable with the larger team and provide a response on Monday or Tuesday next week during business hours.

Best,
Manuel Chavez

In general, the ISO1432 can serve as a replacement for multi-chip isolated RS 422 solutions such as the ISO7720+UA9638. The details of this thread are being handled via email.
