Introduction of E-Cam Operation ASDA Series Application Note
2-22 March, 2015
The definition of constant speed area is determined by the proportion of required constant speed
during material feeding, not the constant speed area generated when cutter is operating.
Different material requires different constant speed area. Thus, to generate different E-Cam
curve is required. That is, the constant speed area is determined by the material.

When using software to create an E-Cam curve, the first step is to know the specifications of the
mechanism. Figure 2.31 shows the specifications that users need to know before creating the
curve.

No matter it is Rotary Shear-W/O Sealing Zone, Rotary Shear- W/T Sealing Zone, or Rotary
Shear- Adjustable Sealing Zone, mechanical specifications is required when creating a curve
via the software. See Figure 2.32.
