– Vc = 1 means there is no speed compensation.
– Vc = 0.9 means the speed of the cutter axis in the sync zone is 0.9 times
of the speed of master axis.
– Vc = 1.1 means the speed of the cutter axis in the sync zone is 1.1 times
of the speed of master axis.
6. To enable macro #7, write parameter ID385 (P5.097)
MacroCmdIssue&Result = 0x0007 to create the E-Cam curve by macro
#7.
7. Read parameter ID385 (P5.097), if it equals to 0x1007 that means the
macro table is successfully created.
If these error codes appear, correct the setting according to the
instructions.
Rotary Shear - Printing Machine
This type of E-Cam curve is applied to a reciprocating printing machine. When
the printing plate is separated from the material, the material is retracted, so that
the printed pattern can be closely connected to save material. Taking paper
printing as an example, the printing axis runs at a constant speed in one direction.
As shown in Figure 184
, when the printing plate makes contact with the paper,
the printing is started at the same line speed as the printing axis. When the
printing operation is finished and the printing plate is separated from the paper,
the dragging axis starts to decelerate and stop, then runs to the specific area in the
opposite direction. Then the previous steps repeat to perform the next printing
cycle. For this type of E-Cam curve, the corresponding relationship between the
required parameters and the mechanical structure of the printing press is shown
in Figure 185
.
Error Codes Error Instructions
0xF071 Cannot make a watch when the clutch is engaged
0xF072 ID382 (P5.094) MacroCmdParameter3 is out of range (0°…330°)
0xF073 ID381 (P5.093) MacroCmdParameter4 (higher 2 bytes) S-curve smoothing level S is out of
range (1…4)
0xF074 ID381 (P5.093) (lower 2 bytes) waiting zone is out of range (-1°…+170°)
0xF075 ID384 (P5.096)MacroCmdParameter1 is out of range
0xF076 ID370 (P5.082) ECamAreaNumber is out of range (30…72)
0xF077 ID 369 (P5.081) E-Cam start address exceeds the data array length
0xF078 Gear ratio ID151 (P1.044)/ID152 (P1.045) too big,
For example:167772160:1000000 changes to 16777216:100000
0xF079 Acceleration zone not enough, make smaller the waiting zone, sync zone, or S-curve zone
0xF07A Waiting zone should be larger or the sync zone should be smaller
