Why Tween Service does not working with Motor6D?

Hello guys, I am making something for my sword using Motor6D I wanna do a simple movement using tweening but for some reason its not working and im not sure why. There are not errors it just does nothing...

local HandPos = {
	[1] = CFrame.new(0,-0.2,0) * CFrame.fromEulerAnglesXYZ(math.rad(90),math.rad(0),math.rad(180)),
	[2] = CFrame.new(1,-0.2,0) * CFrame.fromEulerAnglesXYZ(math.rad(90),math.rad(180),math.rad(180)),
}

Tool.Equipped:connect(function()
	Sabers[1]:WaitForChild("Handle")
	
	if not Igniting then
		for i, Saber in next, ActiveSabers do
			local Arm = "RightHand"
			if i == 2 then
				Arm = "LeftHand"
			end
			local info = TweenInfo.new(1, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut,0,false,0)
			local tween = TweenService:Create(Saber.Handle, info, {CFrame = HandPos[i]})--the problem is somewhere here i think
			tween:Play()
			wait(1)
			ActionWeld(Saber, user.Character[Arm],
				HandPos[i]
			)
		end
	end
end)

I have no point why if you know plz tell me...
