The Industrial Raspberry Pi Forum

Dear team Kunbus,

I am controlling a servo drive with a pwm signal from GPIO3. I set FpwmOut_3 to 10000 and Dutycycle_3 to 500.

Everything is well, the servo drive receives the signal and the servo motor spins with a set speed.

Now, i want to change the speed of the servo motor real-time with RevPiModIO. So i need to change the FpwmOut_3 real-time.

To my knowledge, this is not possible, because it is MEM, correct? The Dutycycle has no effect on the servo speed, only the frequency of the signal.

Is it not possible to make the setting changeable, without setting it in Pictory and resetting the driver?

Best regards! Arjen

Dear Arjen,

No, that is only adjustable in Pictory. There is no way to change the parameters in real-time without setting them in Pictory and resetting the driver.
