 Create E-Cam curve with fixed synchronous speed zone
This method allows you to create a rotary shear curve with fixed synchronous speed zone,
which range is fixed to 51°. You can use ASDA-Soft to create the table, which parameter setting
is similar to the curve for rotary shears without synchronous speed zone, as shown in Figure

7.3.7.10. The software automatically limits the cutting length by referring to the ratio (R) of the
cutting length (L) and the arc length between cutter ends (a); R = L / a; R = 0.07 - 2.5.
You can use Macro #6 of the servo drive to create the table with the same method and the
curve created is the same as that generated with ASDA-Soft. The advantage of using the macro
to create an E-Cam curve is that when changing the cutting length is required, you can create a
new curve simply by modifying the parameters. It is very friendly for those applications that
require frequent modification of the cutting length. The setting steps are as follows:
Set the start position for the data array: use P5.081 to specify the data array start position
1.
for E-Cam and use P5.085 to set the E-Cam's segment number for clutch engagement.
When using Macro #6, P5.082 E-Cam segment number can only be 7, which means the
curve resolution is 51° and the synchronous speed zone is also 51°.
Set the system E-Gear ratio: set the system E-Gear ratio with P1.044 and P1.045.

Set the E-Cam's gear ratio and curve scaling: set the pulse number required for the cutting
