Allowed Values Description
> 0 Enables the variable polygon delay mode. See
= 0 Disables the variable polygon delay mode. (This is the default setting.)
This parameter effects only 3D-applications.
> 0 The x-, y- and z-values are changed directly (linearly) to their end values
during a jump.
While the x- and y-values are changed linearly to their end values during
= 0
a jump, the z-value is changed to its end-value in such a way that the
focus is kept in one plane during the entire jump.
0 ... 65500 This parameter defines a maximum "laser on" time for the corners of a
(1 bit equals 10 µs)
polyline. If the polygon delay is longer than or equal to this value
(because the angle φ is close to 180°, for instance), the laser is turned off
(after a LaserOff delay) and a new polyline is started. This can be useful
for preventing burn-in effects. The edgelevel must be smaller than twice
the set value for the polygon delay, otherwise it has no effect. Also see
figure 9 on page
Note: To disable this feature, set the edgelevel to 65500 (default value).
0 ... 32500 Minimum jump delay for a jump vector of zero length.
(1 bit equals 10 µs)
See figure 6 on page
0 ... 32500 Jump length limit in bits. If the jump vector is shorter than this value, the
jump delay is varied as shown in
jump delay is constant.
To disable the Variable Jump Delay mode, set the JumpLengthLimit to 0.
