Bosch seat motor Programming help

My team has never used a bosch seat motor before. I have been unable to find any programming resources on it. is it programmed just like a normal motor or is there anything else that has to be done to program it. any help is appreciated.

This is my first cd post so sorry if it isn’t laied out the best.

Keep the questions coming.

Really you just define the type of motor controller that you have plugged your bosch seat motor into. What the type of motor is doesn’t matter. Unless it’s a servo.

Best of luck.

Thank you for the help.

To use it as a motor, nothing special. If you want to use the feedback from the motor, you should note that the voltage output from the encoder on the Bosch is at too low a voltage to trip the DIOs on the RIO. You’ll either need to connect it to analog and create an analog trigger, or adjust the signal using a circuit like the one in this kit:

I see it’s out of stock, but you can see the schematic here:

Mr. Michel,

Just trying to get a better understanding here. So are you saying that the voltage feedback from a bosch seat motor can’t be read by the tolerances of the CTRE Talon SRX? I was/am under the impression that the SRX could read those… but my love of learning shows I’m wrong more them I’m correct. I tried to lookup what those feed backs might be, but could not find them.

I’ve been a mentor with two teams (FRC 1711, and 5534) and I alway wonder why they send these motors, which never get seemed to get use (at least with the teams I’ve worked with).

Thank you for allowing me to tip your vesule of knowledge.

I was really speaking about the DIOs on the RIO; let’s check out the SRX encoder inputs:

Page 5 of the SRX user’s Guide:

  • Logic High Min Input Voltave Quad A/B/Idx/Limit Fwd/Rev: 2.64V
  • Logic Low Max Input Voltage Quad A/B/Idx/Limit Fwd/Rev: 0.66V

And from a web page about the Bosch:

Looking at the scope trace, the output of the encoder/tachometer ranges from about 3.5 V to almost 5V, so it will remain high for the SRX as well as the RIO DIO.

I’m convinced the only reason the Bosch Motor doesn’t get more use, despite having a built-in Hall Effects Sensor, plus a Worm Drive that resists Back-Driving, is that is has an unusual 8-point Star shaped shaft bore. 3468 is attempting to use them this year, and I am very excited about the prospect, provided we can find a good way to attach them despite the unusual bore.

There are a few options shown in the WPI screen steps. You can also purchase an adapter from AndyMark.
