Parameteres Data Format Explanations
P1 Slave position 1 Integer Caught at DOG signal
P2 Slave position 2 Integer Caught at end of cycle
P3 Master position 1 Integer Caught at DOG signal
P4 Master position 2 Floating point Caught at end of cycle
P5
Master position 3
Floating point
Caught at START0(M1746=OFF) or
PG0(M1746=ON)
D1849, D1848
D101, D100
D103, D102
T(ms)
Slave position caught at DOG signal
Current position of X-axis
D105, D104
D107, D106
D1863, D1862 Number of accumulated MPG pulses
E-CAM cycle
Slave position caught at end of cycle
Master position caught at DOG signal
Master position caught at end of cycle
The function of reading E-CAM status in capture mode should be used with M1757 (
Remain current speed
), and
can be applied for checking the cutter position in flying saw applications. For details please refer to 9.4.2.6.
9.4.2.1 E-CAM Data Real-time Modification
E-CAM Data set in E-CAM Chart will be downloaded into DVP-PM with the user program. Due to that
E-CAM Data can only be modified by PMSoft, users have to download E-CAM Data again after modification.
Aiming at this problem DVP-PM also provides users with E-CAM Data real-time Modification function by
DTO/DFROM instruction
Data length of E-CAM Data can be real-time modified. When 4 words of one point (set) of E-CAM Data are
all 0 and identified, DVP-PM will take it as E-CAM completion. Therefore, if you want to modify 10 points
E-CAM Data into 5 points, DTO instruction can be applied to write 0 into the 4 words of the 6
th
point.
„ Application Example
Modify the original E-CAM Data (existed data or no data) as diagram (a) into the 3-point E-CAM Data as
Diagram (b) with coordinate (0, 0), (16000, 10000) and (32000, 0).
