MECHANICAL DETAIL
Cartridge Tilt
Mechanism
The cartridge is tilted by a moving coil motor and gearbox which is driven from
MultiMove X12 in the machine controller.
Two channels are used to allow bi-directional drive. Positional control of the
cartridge tilt mechanism is by the use of cartridge horizontal (up) and cartridge
vertical (down) sensors, which feed via MultiMove X12 and the CAN bus to the
NextMove card in the PC, which in turn controls the MultiMove X12 drive output
to the cartridge tilt motor. On its own this system would not position the cartridge
repeatedly so hard stops are provided for the cartridge horizontal (up) and
cartridge vertical (down) positions and the motor drives the unit against these
via a clutch mechanism.
