MKS SERVO42C, an upgraded version of MKS SERVO42B, built-in Field-Oriented control algorithm, position/speed/ torque closed-loop, 4 Half bridge driver with 8 MOSFET, it makes the motor quieter, lower vibration and Lower calorific.
In the schematic there is:
"Only one group of Q1,Q2,Q3 and U8,U9 can be selected for welding."
Welding is the wrong translation for what presentably should be soldering. Regardless replacing this word entirely might be feasible.
Also it might be feasible to not draw them as two separate set of components using the same PCB footprints and traces. Instead note the allowed substitution on the BOM.
