WEhen in bridged mode only S1 is required(when using RC or Analog controls, Packet serial still uses both S1 and S2). The motor controller must be told to use bridge mode(checkbox in General Settings in IonMotion setup app). It will then properly sync the two motor channels PWM so they match exactly...

You only need to protect the main power source from the Roboclaw. The Roboclaw has its own current limiting control for each individual motor. Yes, worse case two motors that can pull 45a(at stall) can pull a maximum of 90a from the battery(assuming 100% duty on both motors). Let me try to simplify ...

The Roboclaw sounds like it is a V5 board(or newer). It also sounds like it needs to have the firmware updated to 4.1.19 or newer. This should swap the Mode and Lipo buttons automatically. It sounds like they are currently setup for the V4 format. Eg Lipo is actualy functioning as Mode and Mode is a...

1. E-Stop triggers a braking state on the motors(unless the motors are already in an errorstate(eg if in an undervoltage state the motors are left to coast until the voltage rises above the minimum limit. If in this state an e-stop is triggered the motors will not enter braking state but remain in t...

Choosing a fuse or breaker can get very complicated if you want to protect the system as much as possible. You have to take into account the actual current the motors will pull at a given duty cycle. Then exstimate the maximum current and for how long it will need to pass that current before fusing/...

That didnt really answer my question. On the schematic the connections at the three Roboclaw conenctors of you PCB have TX and RX labels. Is the TX pin of that connector going to S1 or S2 on each Roboclaw? If the TX pin on your PCB is going to S2 on the roboclaw then you have the wiring backwards. T...

Which orientation are the RX and TX labels in relation to. RX to the Roboclaw or to teh UART? Im assuming it is in relation to the UART so RX is the transmit(eg S2) from the Roboclaw to the UART. If so it looks correct though it is hard to be sure since some traces pass under each other that look to...

The stronger the pullup the faster you can transmit over a bus. However any value between 4.7k and 1k should be ok. What ever you have available. Without seeing your circuit I cant say the logic level converter will work. When the roboclaws are setup for multi-unit mode they only pull the line(S2) l...

Currently you can not. We are planning on adding the ability but I'm not sure it will be in the next release.

If there is not a lot of slop then the autotune would work ok. The auto tuner works best with minimal backlash(slop) and reasonable resolution encoders. It has problems with linear acuators for both reasons, a lot of backlash and very low resolution analog encoders. For the velocity autotuner it wan...
