Segment Shape Specifies the segment shape.
Time/Frequency/Rate Specifies how fast the segment runs.
The following methods are supported:
• Time specifies the time to run one segment.
• Frequency specifies the time to run a two-segment cycle (even though a
single segment runs).
• Rate specifies a constant rate between the starting level and the end level.
Rate is typically used with a ramp segment.
Note You cannot use Rate for a command process applied to multiple
channels. If you do, an error message will appear when the procedure
is locked.
Adaptive
Compensators Enables command compensation during the command process. The Adaptive
Compensators list includes all compensators available on at least one channel
selected in the Channels tab. It is important to know which compensator is
available for each channel in your station configuration because when this
process is run, compensation will occur only on the channels for which it was
enabled.
Note A special annotation appears if the compensator is not available on all
channels. For example, “AIC (1 of 3)” implies that the AIC
compensator is only supported on one of the three included channels.
Important The use of the AICX compensator can introduce large delays
between generated command and command to the actuator.
The delay is dependant on the tuning of AICX and is two times
the value of the Impulse Response.
Do Not Update
Counters Disables the counters. When enabled, the Channel Counters do not increment
for this process and the counter totals are unaffected.
Relative End Level Makes the end level relative.
Channel Specifies the channel.
