Dear all,

I have a Roboclaw 2x5a v3.0.9. (bought via Pollin) on my Desk. I have problems using the speed control. I have set up two motors with Quad encoders with 240000 QPPS (measured manually).

PID values are default.

When using the set Duty mode (-1500,1500) everything works fine , but the speed controller doese'nt.
I guess the speed is given in QPPS, at least it is the output when reading the speed value (when run in duty mode). Here is the effect I observed

When setting
SetM1SpeedAccel(120000,120000) I would expect the motor during with 50% within 1 sec, but the motor turns with 100% in zero seconds.
The same is true for any value >10

When setting SetM1Speed with a value (0-500) the motor also starts turning very slowly until 100%.

Am I doing anything wrong?

Is there a way we can do a firmware update? We have bought the device via Pollin.

Cheers,

Markus

Default PID values wont necessarily work for your motor. Yes you can send it in for a firmware update. Just include a return shipping label and there will be no charge.
