No Abbr. Parameter function and description
PC88 CSDS
Command code
0007h
Create E-Cam table: rotary shear (adjustable synchronous
speed zone)
General
parameters
PC59 = Start address ( data array)
PC60 = N(30~72)(E-Cam segment number)
PA06,PA07 E-Gear ratio need to be set firstly.
Macro parameters
PC84.H16(high word)(Hex) = S(S-curve smoothing level,
range 1 - 4)
PC84.L16(low word)(Hex) = W(degree of waiting zone,
range -1 to 170 degrees)
PC85=Y(degree of synchronous speed zone, range 0 - 330
degrees)
PC86.H16(high word)(Hex) = A(number of teeth on the
motor) * C (cutting count)
PC86.L16(low word)(Hex) = B (number of teeth on the
cutter)
PC87 = 1000000 * R * V(range1.88 > R x V)
In which:
R (cutting length ratio) = L (target cutting length) /
ℓ
(perimeter of cutter)
V (speed scaling) = cutting speed / feeding speed
Example:
V = 1.0: during cutting, the speed of cutter is the same as
the feeding speed
V = 1.1: during cutting, the speed of cutter increases 10%
V = 0.9: during cutting, the speed of cutter decreases 10%
Supplementary formula:
W
’ = 180 +(360 / N)-(360 / R)+(Y / 2)
When
① PC84.L16 < W ´ ,E-Cam table is in error(failure code F07Ah).
② PC84.L16 = W ´ , initial speed is 0 in E-Cam table.
③ PC84.L16 > W ´ , initial speed > 0 in E-Cam table, W must be set to -1.
