How to control (run stop, freq reference) Altivar ATV12 via remote terminal VW3A1006, VW3A1007

From factory setting you need to enter conf menu and set FR1=LCC
Then run and stop buttons on remote terminal will work, but display by default will not show frequency reference. Instead motor speed is displayed.
To change freq setpoint on remote terminal, it is necessary to enter rfr menu and select frh. Then freq reference will remain on HMI. Simultaneously, RFR LED diode on HMI will be lit. If the led diode is not lit, rfr menu is not active (and motor speed is shown on HMI).
