SD540 Motor Controller
 

The SD540 Motor Controller is now shipping! A seemingly weightless, low cost solution with great functionality is now here and ready to order.

We had great feedback at the recent FRC workshop in Richmond, VA. Many local teams got a chance to experience using the SD540 Motor Controller first hand and witness its amazing control.

Re: SD540 Motor Controller
 

Do you have a CAD model of the controllers? I looked around the website but didn't find them, I'd like to add them to our CAD library.

Why are the dip switches on the bottom of the unit, seems like it would make it difficult to adjust once they are on the robot.

Go to the product page, and click on the download tab on the left hand side of the page.

My 2 seem fine, thanks!

Re: SD540 Motor Controller
 

Thanks, I thought I looked there but I guess I missed it.

SD540 Motor Controller Comparison
 

See how the SD540 Motor Controller compares with the other FRC controllers available:


The majority of the information on this chart has been taken from the comparison chart form REV Robotics.
See their chart here:

Similar charts can also be found in Talon SRX, Victor SP, Victor 888, Talon SR, and Jaguar documentation.

Re: SD540 Motor Controller
 

Quick question, does having a higher output frequency cause any sort of performance difference?

Re: SD540 Motor Controller Comparison
 

Not to be a buzz kill but did you guys just copy the data complied by REV for the Spark? Even the disclaimer is the same.

Re: SD540 Motor Controller Comparison
 

I would compare this to the Spark or Victor SP. In terms of weight it beats both, is only $5 more expensive than the Spark, has a limit switch input, and has a thinner form factor than the Spark (although not as flat as the others). The output frequency is also higher, although I'm not sure what effect that has.
The banking option looks handy to slightly lower the cost and use less mounting hardware.
Looks pretty neat, overall! We would buy them if not for the twenty Talons we already own. :P

Re: SD540 Motor Controller
 

Higher switching frequency will make thing more efficient, and power delivery will be continues rather than discrete. In other words better linearity and smooth operation.

Re: SD540 Motor Controller
 

What does "multi-bank" mean? I see nothing on the web pages that gives me even a hint of a clue. The price sounds pretty good, but perhaps if I understood what "multi-bank" means it would actually be worth buying.

Re: SD540 Motor Controller
 

I'd like to know how the upgradable firmware works. Can you shed any light on that?

Re: SD540 Motor Controller
 

Packaged as single, dual, or quad

Re: SD540 Motor Controller
 

If you scroll down the the bottom of the webpage, you'll see there's a "pod" of 4 motor controllers referred to as the "Quad-Bank Model" and a subsequent Dual Bank Model. It's essentially a block of motor controllers.

Re: SD540 Motor Controller
 

At the workshop they said you could replace one of the controllers on the bank without having to replace the entire bank. Not entirely sure how that works in relation with the rules though.
