Enable Ramp If selected, the process will ramp to the specified setpoint before beginning to
taper to the specified amplitude.
If not selected, the process will begin to taper to the specified amplitude from
the current level.
Ramp Time If Enable Ramp is selected, Ramp Time specifies the amount of time the
command ramps from the starting level of the process to the specified setpoint.
If you set the Ramp Time to zero, the controller will use the Setpoint/Span
time specified on the Station Manager Channel Options Command Options
tab.
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.
Change Setpoints Enables the Setpoint control.
If disabled, the Setpoint will remain unchanged.
Change Spans If enabled, the process will play out whatever percentage of full scale
amplitude is entered in the Span box of this window.
If disabled, the process will play out whatever percentage of full scale
amplitude that is specified for the system span value. The system span value is
set in Station Manager. (Pressing the Span Setpoint button on the Station
Controls panel displays the Setpoint and Span window.)
Enable Soft Stop If selected, the process will ramp to the specified setpoint before stopping.
If not selected, the process will stop at the current level.
Channel Specifies the channel for which the controls on this tab apply.
Control mode Specifies the control mode. Only control modes that have the same dimension
as the channel’s external input signal are available.
