motion.spindle vs spindle

I have 2 spindles in my mill 1 to z axis 1 to y axis  iso40 taper that have sensor for tool detection and hydraulic electrovalve for locking tool.
Also each spindle has gearbox with 2 positions
with sensor in which position is and hydraulic electrovalve for changing gears to position 1 or 2.
I plan to use encoders on spindles for rigid tapping.
The spindles can't driven together because there is only 1 inverter and selection which spindle will work is done via 3 phase relay.
Inverter gets -10v +10v analog input and enable signal.
real time splindle hal component supports gears but motion.spindle not.
Which component must use spindle or motion.spindle?
pncconf by default setup in config motion.spindle how can use gears 1 and 2 for motion.spindle?
