My mission is to connect 2 motors, 2 converters and control them with Logo TD push-buttons. I managed to do start/stop forward/reverse with F1,F2,F3,F4 buttons. But i do not know to make logo change frequency with cursor buttons up/down, so frequency goes 0,1,2,3 and to max 50Hz and other way. And also that screen shows frequency change. I have analog output card AM2 AQ and it is already connected. Thanks for any help.

If the convector has 1 analog entrance which it is possible to enter parameter on frequency change by means of a signal of 0-10 V / 4-20MA. This signal will move by means of an analog output of the module AM. Also if the basic logo is the module 12/24. That can be established feedback and to see the actual frequency on the motor.
