Segment Shape Specifies the segment shape.
Time, Frequency, Rate Specifies how fast each 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.
• Rate specifies a constant rate between the starting level and the end
levels.
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.
Note The rate of the first segment can be faster than the other segments if it
must transition from a distant end level.
Count Specifies how many times the waveform will be repeated.
Note If you clear the Count box, the waveform will repeat continuously.
Adaptive
Compensators Enables command compensation during the command process.
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 Levels Defines the segment end level:
• Absolute End Level is relative to setpoint.
• Relative End Level is relative to the starting command value (the value
when the process begins).
Channel Specifies the channel.
Control Mode Specifies the control mode or control-mode variable.
