How to control direction using +/- 10 VDC Analog Input ?

I have + 10 & - 10 VDC Input coming from PLC and I want to use them to change direction ?

By which parameter I can do that in SINAMIC V20 ? Thanks

Split from V20, why change direction using mop!.

You could use a signal conditioner to convert the +/-10V signal to 0-10V signal compatible with the V20 AI's.  Then scale the AI signal 0-5 as reverse, and 5-10 as forward.

Or, you (since you have a PLC), wire a digital output for direction control and use just 0-10V of the PLC Analog Output channel.

 Is it possible to scale - 10 V & + 10 V to change direction, I need to do only in VFD ? Can do any thing in PLC

What kind of PLC?  Do you have the direction input wired between the PLC and the V20?  If so, when the voltage [would be] negative going to the VFD, set the direction for reversing and send the absolute value of the |speed setpoint| to the analog output.

If it is a Siemens PLC with Profinet, use a telegram and everything gets easier for PLC / VFD control and feedback.

I found V20 have AI1 which can read -10 to 10V so you need connect wire to AI1 and then set P0756 to 4 look at here and read carefully Notice:
