Re: Stepper/BLDC Motoren mit Revpi ansteuern

Hallo Borhen, ich persönlich würde dir nach wie vor eher zu einer Ansteuerung per AIO + Motion Controller + BLDC raten. Denn ein weiteres Problem bei der Variante mit DIO+Schrittmotor ist das Drehmoment, dass mit zunehmender Geschwindigkeit geringer wird, was dann leicht zum stall führt. Du müsstest...

Re: Stepper/BLDC Motoren mit Revpi ansteuern

Hallo Borhen, Ich will nun den gleichen Aufbau auf dem RevPi erledigen. Ich habe das DIO Module mit dem RevPi, wie in den Tutorials, verbunden, die beiden OUT und IN LEDs von DIO sind dauernd Rot, Power ist Grün. Was soll ich jetzt tun ? Wie verbinde ich den Treiber mit dem RevPi ? Wenn du den Treib...

Re: Stepper/BLDC Motoren mit Revpi ansteuern

Hallo Borhen,
Schrittmotoren oder BLDC Motoren sind nicht direkt über DIOs oder AIOs anzusteuern.

Von Faulhaber zum Beispiel gibt es aber Controller für BLDC-Motoren (z.B. MCBL 3002) die sich per PWM (DIO) oder einem Analogsignal (AIO) ansteuern lassen, die könntest du dir mal anschauen.

Re: RevPi AIO input - flashes red

Hello,
this indicates an input range error(https://revolution.kunbus.com/tutorials ... revpi-aio/).
Can you check if one of the inputs is configured as 4-20mA input?

Re: Revpi Core3 DO failure

Hello,
firmware updates for the AIO, DIO, DI and DO are now available.
Update the revpi-firmware package and follow the instructions for Connect and Core .

Re: Possible bug in the RevolutionPi Data IO driver

I had your python script running over the weekend on a connect+ and a dio. One input was pulled high with a 4.7k resistor to Vsupply (24V).
There was no "emergency stop" reported in this period.
Can you check your wiring again since the error seems to appear more often in your last setup.

Re: Revpi Core3 DO failure

Is that "my" bug or a seperate one? Is the FW for the AIO also on short final?
Yes it's the one you reported. We will release firmware updates for AIO, DIO, DI and DO modules before Christmas.

Re: Revpi Core3 DO failure

Hello Luuk,
what you are seeing is a known bug where timeouts on the modules are falsely triggered. Due to the timeout the outputs are switched off.
We fixed the bug and are preparing a firmware release right now which will be available soon.

Re: Possible bug in the RevolutionPi Data IO driver

Hello Chris,
is the input pulled high by the supply or is it pulled high by a digital output?

Re: DO module default values

Hi Abel, i was able to reproduce your problem. Let me guess. Your AIOs are left of the digital modules? In this case there seems to be a bug where the initial output values are not applied correctly. We will look into this. As a workaround you can try changing the order so that the analog modules ar...
