welcome :-)
and please read [1] carefully, e.g. also add what is your Yade version (sometimes there are changes, that might be important for the problem) etc.

thanks for the code.

therefore the code posted should be a MWE [1], M = minimal.
Something like this, a short code focusing just on the problem.
###
bot = (
    sphere((0,0,0),1),
    sphere((2,0,0),1),
    sphere((0,2,0),1),
    sphere((2,2,0),1),
)
top = (
    sphere((0,0,3),1),
    sphere((2,0,3),.5),
    sphere((0,2,3),.5),
    sphere((2,2,3),1),
)
botIds = O.bodies.append(bot)
topIds = O.bodies.append(top)

harmRot = HarmonicRotationEngine(
    ids=topIds,
    rotateAroundZero=True,
    rotationAxis=(0,0,1),
    zeroPoint=(1,1,0),
    A=1,
    f=1,
)

fResetter,collider,iLoop,timeStepper,newton = O.engines
O.engines = [fResetter,collider,iLoop,harmRot,newton]
O.dt = 1e-6
###

if this is what you are expecting and your code does not work as expected, you can think what is different, add relevant parts to the MWE and iterate similarly.
This way, there is also higher probability that you find the problem yourself.
So please try to create a MWE, i.e. deleting the deposition and compaction and just add a few "representative" hardcoded spheres (i.e. if particles are far away, make them far away, if they are touching, make them touching etc.), deleting not important PyRunners etc.

Cheers
Jan
