Hey Soutish, yes, the settings are different because the buildbotics-derived Onefinity controller of the Original/X-50/PRO Series controls VFDs with Modbus via a RS-485 serial communications interface (two-wire interface), while the MASSO G3 Touch of the Elite Series unfortunately does not support Modbus and has to control the VFD through a programmable input terminal for FWD/REV/STOP spindle and a analog 0–10 V voltage line for SPEED (FREQUENCY). Therefore the settings for “source of RUN commmand” and “source of frequency/speed control” must be set differently depending on which CNC controller you have. Luckily nearly all VFDs I know support both methods. Regarding wiring, here is a table that shows the wiring when using the spindle control cable: - [Huanyang VFD wiring to Elite Masso G3 Touch](https://forum.onefinitycnc.com/t/huanyang-vfd-wiring-to-elite-masso-g3-touch/21870/5) Welcome to the forum! --- _[View the full topic](https://forum.onefinitycnc.com/t/masso-vs-buildbotics-vfd-parameters/27675)._
