Bidirectional PWM: How to set up correctly

[George]

Hi all

To control a single coil PCP in bidirectional mode you can use a pair of MF output pins on FI a MC024 controller.
You need to set the .Pinconfig to 8. That far seems simple, but then:
What do I use best to get the signal translated through the "outputs" bus?
A standard PWM Driver function block seems not suitable since it doesn't support negative values...

Probably there is a simple solution, but what is the cleanest / recommended way?

Hello,

I have attached a Picture where you can see, how I handle with the "negative" values and the PWM.
Maybe this helps you with your Problems (as far as I have understand it right).

Have a nice day !

I agree this is could be a working method, but it isn't clear since there is no mention on what to connect to the output pins if using .Pinconfig8
In the end I've used a S90 Function block, which sets both ports to .pinconfig 4 internally. and connects to both pins

Hello,

When I have a bidirectional Signal, I always set the.Pinconfig of both Pins to 8 and connect the Outputs to the Output value and it works.
For example:
I use a MC012-110 and use C1p11 and C1p12 for my bidirecitonal control.
So I set the .PinConfig of the C1p11 and C1p12 to 8 and connect the signals to the Output values of C1p11 and C1p12.
