Motion Control

 E-Cam curve plotting

On the horizontal packing machine, the chain conveyor, wrap feeder, and cutter all require

E-Cam curve settings. Both the chain conveyor and wrap feeder follow the master axis pulses

for constant speed motion, which makes the E-Cam curve a slope. You can complete the setting

with ASDA-Soft. Regarding the cutter axis with heat sealer, use [Rotary shear - adjustable

sealing zone] in the ASDA-Soft to complete its E-Cam curve.

1. Cutter axis: select [Rotary shear - adjustable sealing zone] in the ASDA-Soft and fill in the

packing machine specifications in the table, as shown in the following example.

For detailed settings, refer to Section 7.3.7. In this example, the master pulse number is

automatically calculated by the software, which means the E-Gear ratio P5.084 = 79577

and P5.083 = 1. Set the E-Gear ratio by setting P1.044 to 16777216 and P1.045 to

100000.

2. Wrap feeder: select [Manually create a table] in the ASDA-Soft. See the following example.

The roll diameter for dragging the packing wrap is 20 mm, so the wrap feeder feeds the wrap

of 62.83 mm per roll revolution. A cutting length of 500 mm requires 50,000 PUU. Every time

the machine operates 50,000 PUU, the motor operates 250,000 PUU. In this case, set the

E-Gear ratio by setting P1.044 to 16777216 and P1.045 to 50000 and create a constant

speed E-Cam curve with a total lead of 250,000 PUU. The E-Cam gear ratio of this axis

must be consistent with the cutter axis, which means P5.084 = 79577 and P5.083 = 1.

3. Chain conveyor axis: select [Manually create a table] in the ASDA-Soft. See the following

example. If the command resolution is 1 mm corresponding to 100 PUU, then each chain

interval of 500 mm requires 50,000 PUU.
