U511 User’s Manual Parameters
Version 1.1 Aerotech, Inc. 4-93
4.11.7. “Segment time” (1-20 ms)
During trajectory generation, the UNIDEX 511 divides the motion into segments. These
parameters represent the motion time for each segment (in milliseconds [ms]). The
default setting of 10 ms is sufficient for most applications. If the application requires
many short moves with short ramp times, you may wish to reduce the value of this setting.
The minimum value is one millisecond.
These parameter values can range from 1 to 20 ms for each of the planes under command.
The system default is 10 ms. Refer to Table 4-67.
Table 4-67. Settings for Parameters 018, 036, 054, and 072
Param # Plane # Range Examples
018 1 1-20 ms 1 = Provides the slowest calculation time
and yields the maximum number of
indexing segments
10 = Provides a moderate calculation time
and yields a moderate number of
indexing segments (default)
20 = Provides the fastest calculation time and
yields the minimum number of indexing
segments
036 2 1-20 ms see examples shown above
054 3 1-20 ms see examples shown above
072 4 1-20 ms see examples shown above
This parameter will not increase servo velocities in any way. It may be used to
improve the processing efficiency of the calculation effort during trajectory
generation.
