Absolute and quadrature encoding
Posted: Tue Mar 05, 2019 12:46 pm
Hi,
Scrathing my head on this one, have a two motor setup with one using absolute and the other using quatrature encoding.
Both motors work and provide feedback only via Encoder M1 and only relevant encoding selected on that particular motor on M1 ie Quad or abs. will it provide feedback.
It seems both motors are therefore connected to EN1 inputs, which they are physically not. One motor is definetely connected to EN2 input.
Using the same hardware I connected 2 x qaud. motors and encoder inputs report position info.correctly.
So little confused here as to why the two encoders want to report back via M1 encoder only, have checked my encoder wiring (using a 15K pullup for the abs input) and it appears all good.
Testing with Roboclaw 7A and with ionmotion windows software.
Any guidance appreciated.
Thanks,
Rob.
