8 Electronic Cam8.9 Application Examples (Application of H3U-PM to Strapping Band Winding Machines)
2) Master/Slave Axis Length
The number of pulses generated per circle in which the master axis encoder rotates is 2500 x 4 = 10,000
pp (a 2500-cable A/B phase encoder is used, and a multiplier 4 is used for high-speed counting). The wiring
ranging servo motor is directly connected to the screw rod through the coupling. 10,000 pp of pulses are
generated per circle in which the servo motor rotates, and the screw pitch is 5 mm.

250/12.5 = 20 circles: Indicates the number of circles in which the strapping band is wound from A to B.
Master axis pulse: 20 x 10,000 x 2 = 400,000 pp
Slave axis pulse: 20 x 10,000 x 12.5/5 = 500,000 pp
