By the setting itself it is not possible to configure 0-10V analog input signal and assign it to bidirectional reference.
However, with one trick it is possible to manage it. For this purpose another analog input must be used, configured as voltage type and connected permanently to 10V (possible to connect it directly to ATV-10V terminal).
Then it is necessary to use summing reference. If we use AI1 as frequency reference and AI3 as temporary input (10V) to manage the scaling, then the setting must be as shown in attachment.

Bear in mind that other setting must be:
FR1=AI1, AI1T=voltage, UIL1=0V, UIH1=10V, AI3T=voltage, UIL3=0V, UIH3=10V
With summing input we will get:
Reference = FR1 + AI1 (summing input) - AI3 (subtracting input) = 2xAI1 - AI3

If AI3= always 10V, then we get
AI1=0 ---> reference = -HSP (corresponds to -10V)
AI1=5V ---> reference = 0 (corresponds to 0V)
AI1=10V ---> reference = +HSP (corresponds to +10V)
