Changing voltage polarisation

<< < (2/2)

bgtwuk:
I thought that you can use the pin 40 and pin 50 to form an H bridge.

Or am I on a different angle?

Stefan:
Hello,

Yes, that's correct. But the H-bridge just change supply and ground between 2 pins.

You don't get a negative voltage related to ground.

Best regards
Stefan

I have sucessfully controlled a Rexroth PID controller that require -10 to +10 VDC signal using a H-Bridge output.  It is my understanding that with most devices simply reversing the polarity will work.   I set the PWM freqeuncy to 4000 Hz but I still had to use a RC filter to smooth out the signal.
