Re: Bridged Mode Information Inconsistency

The bridge mode wiring is now shown when you enable dit using Motion studio. Motion Studios wiring diagram is the correct one to use(eg its the one tied to the specific firmware being used). Always use the Motion Studio wiring diagram when setting up Bridged mode. We are in the process of removing t...

Re: Issue with RC mode

This is likely caused by your receiver. Many receivers have a failsafe throttle setting(primarily for airplanes). You need to disable this feature. Otherwise when signal is lost the throttle will be set to 1/3 power(not center) and the motors will take off.

Re: Roboclaw 2x60 with servocity super duty linear as servo

Electrical noise the most likely cause in that case. Add a .01uf cap from the analog signal line to ground. That should clean it up. The pot is linear so your 360 degree value in the calculation is where you got it wrong. You need to know the number of turns the motor takes for a complete movement a...

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

For battery-powered things like that, I don't recommend voltage clamps. You'll want as much of the regen energy back in the battery as you can get I expect. Unless you're going to use the 90C limit of the battery I'd probably set the fuse so it would blow around 300amps(about mid way between the 45C...

Re: Roboclaw 2x60 with servocity super duty linear as servo

Show your math for calculated QPPS. I may see the mistake. Obviously, the measured speed is the best value to use for QPPS. Everything else should be 0 when you start. Then set P to something low(5 for example). Move the position slider to a new position. The actuator should move toward the target. ...

Re: Reset encoder through Basic Micro

You can not zero an absolute encoder. Because they are absolute encoders. Every position has a unique value. I believe I talked with you on the phone yesterday. You remembered then you originally had a resistor as we defined in the user manual in series with the 5v input to the pot. Once you put tha...

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

1. A 1/4watt resistor will be fine. For a 1 second charge time, it will not dissipate anywhere near more power than it can handle in that time period. 2. The fuse should be in series with SW5 but still parallel to the diode. If the fuse or SW5 is opened the diode will continue to provide a path back...

Re: Roboclaw 2x60 with servocity super duty linear as servo

QPPS is the top speed measurement so 360. I recommend setting it slightly higher than the actual top speed. You should never change the PWM mode to Locked antiphase unless you have a specific application that requires it. Otherwise leave the default set to Sign Magnitude. Make sure you are using the...

Re: encoder count does not change with Duty/PWM commands

Just so everyone is on the same page, I have reproduced the problem. It is exclusively tied to the position deadzone setting. If you only set a deadzone and leave everything else at defaults you can reproduce the problem. If you dont use deadzone the problem doesnt happen. I will look more closely a...
