Hi, Everyone

I am learner, I need help on 👇 question,

"How I get analog output from plc +/- 10vdc(cpu 313c) to control motor direction through VFD(Parker)", i.e which integer value i should move at analog output PQW750 to get+/- 10vdc, without direction command (Digital input)to VFD.

Thank you 

Hello,

things belongs to the VFD if this device can turn direction without digital signal only with +/-10V. If so the 0 Volt is stop, +10V is Max speed in one direction, -10V in the other direction.

 Thank you for your Support, That's right but how can I program for Same, what up to Integers value for +10, 0, -10vdc , And one more question is "can I get -10vdc at analog output channel by moving unsigned Integer values (+Integer values)?
