What kind of motor driver is commonly used with Maxon EC 45 flat and will it improve motor precision?

Hello, sorry for this silly question (I’m ME student and have just started my journey on this field.) I already have Maxon EC 45 flats in inventory. It doesn’t have encoder with it and to get it installed might be too difficult. So, I’m looking for motor drivers and inverters. According from datasheet 1-Q-EC Amplifier(in picture) is usable and become one of my choices (for mentioned purpose). Despite of that, I’m still not that sure about my choice as “clear” reference to prove my decision is true rarely be seen.
Any alternative driver or inverter suggestions are appreciated.
Thank in advance :)
