How to set AB encoder in TMCL-IDE?

zhejiang on Apr 18, 2025

Category: Hardware

Product Number: TMC9960

My BLDC motor encoder outputs+5V, A, B, and GND, without Z. If A and B are connected to GPO15 and GPO14 of TMC9660 respectively, how to set this encoder in TMCL-IDE?

Hi zhejiang,

I think you've used the wrong GPIOs (e.g. GPIO14 can only be used as the optional Z for ABN1)...

See inside the TOML file, there are some commented GPIO numbers that are supported for the ABN1 and AB2 encoders:

Hope this helps.

Best regards,

Paul
