Cyclic Command Process
MTS MultiPurpose TestWare® Command Processes 187
Cycles and segments You can repeat cycles or segments. Two segments create one cycle. Repeating a
full cycle first goes to End Level 1 and ends at End Level 2. Repeating a
segment can end at End Level 1 or End Level 2 (depending on whether the
count value is odd or even).
Repeating Cycles and Segments
Note The end levels selected in processes such as Segment Command or
Cyclic Command can be set to values greater than the full scale preset in
Station Manager. The command will attempt to reach the specified end
level; however, the feedback will become saturated before reaching the
specified end level and will cause a hydraulic interlock.
End levels The two end levels specify the amplitude of the cyclic waveform. When two test
command processes with different end levels are sequenced, the transition
between them is accomplished at the rate and segment shape of the following
process. This provides a smooth transition between test commands.
The conventional way to
define the duration of a
cyclic command is by
frequency or time.
End level
Start level
End level 2 = 5 kip
End level 1 = 0 kip
Frequency = 5Hz
Rate = 5 kip/1 second
Time = 0.1second
