3BUS 208 000 R1301 9Product Overview
Drive System
The upper and lower carriages are traversed across the web by the drive system.
The principle of operation is shown in Figure 1-4.
Figure 1-4 Drive System
The drive motor is a three-phase, variable frequency AC gear motor. The motor
controller supplies the drive wave forms. The drive belts are 2 inch (50 mm) wide
and made of steel-reinforced polyurethane.
A pneumatic, self-aligning head separation clutch at the middle of the drive shaft
allows for head separation.
The encoder gives a positioning pulse train consisting of A and B quadradture pulses
and an index pulse. The software counts pulses to establish the head position. A
home limit switch is used to reset the counters and establish position reference.
