MDDS30 and single input potentiometer
Posted: Fri Jun 05, 2020 5:33 pm
Hi to all.
I’m new in this world (robot modules), but I’m a PCB designer, an electronic.
I bought a MDDS30 driver because I would to pilot 2 (two) 24VDC 350W motors at the same velocity.
My application is a toy car PEG Perego SuperGaucho 24V. The accelerator pedal is a 5K linear potentiometer (single).
The analog inputs are two, one for each motor: I would to pilot the motors simultaneously, with that single potentiometer. Is it possible?
If I connect the single pedal in both ANALOG INPUT (in parallel) what could happen?
Instead of doing this, if I connect both motor in parallel mode on one channel and I leave the second empty, is it dangerous? One channel drive a 28-30A current and other 0…. It could be dangerous? This configuration could brake MDDS30?
Thankyou in advance for your help!!
