Putting limit switches on BL1500

Putting limit switches on BL1500 was created by Anonymous
We were trying to put on a few limit switches on your BL1500 to try and stop the motor. We were doing this be putting the switches on the M1+ and the M2+ wires. After doing this the controller only outputs a power of 31 but on our other controllers have an output in the 120 range. Is there a better way of putting the limits switches on and how can we get the controller to go back to outputting a power of 120?

I don't see any reason why the limit switch would cut the max power. Please explain with more details what you see vs. what you expect.
Regarding where to put the switches, putting them on M1+ and M2+ should stop the motors but there will be no way for you to get the motor to turn the other direction.
Also, when the controller senses that the motor is no longer moving, this will trigger the stall protection, cutting the output until you send a 0 command or a command in the other direction.

Now when we hook up the motor controller, without the limit switches, to the roborun program and move the slider to the max position the power output on the graph is only around 31, something seams to have happened to the controller to limit the max power. With the other controllers and the same setup the power reads around 120. The change in the controllers behavior didn't happen until we put the switches on, we thought that this could have reset the board or caused some sort of fault that then only allowed the 31 power. We have tried using a different motor and a different power supply but the result is the same.

The only way that power can be smaller than command is if current limiting kicked in, or if you have less than 100% in the "Output Power Gain" parameter in the Power Output tab of Roborun. Make sure you use the latest version of roborun.

The power output gain was the problem. Thank you for the help.
