2. Apply a compressive force command that is 80% of the range’s full
scale.
Stand-Alone:
A. Enable the front panel Dial.
B. Using the Dial, adjust the Setpoint for a compressive force
command that is 80% of the full scale range.
C. Verify that your force transducer feedback signal is 80% of the
full scale range.
Automated:
A. Open the Manual Command window, and then click on the
Enable Manual Command.
B. Adjust the Manual Cmd slider on the Manual Command
window for a compressive force command that is 80% of the
full scale range.
C. Use the Station Signals panel to verify that your force
transducer signal equals 80% of the full scale range.
During the initial calibration and tuning of your system, it may
require repeated adjustment for the compressive force command
and feedback values to match.
Note If the actuator response is sluggish and/or the signal value does not
match the command, you will need to adjust the tuning of this
control mode. Increase the proportional gain (P Gain on the Tu n i n g
menu) to correct sluggish actuator movement. Increase the reset
integration value (I Gain) to help the feedback match the command.
At this point, unless the conditioner is already in calibration, the
compressive force applied to the force transducer will not equal
your commanded value. You will adjust Delta K in the next step
so that the actual compressive force and your commanded
compressive force match.
Example: Suppose your actuator has a 100% compressive force
rating of 10 kN. In this step you would apply 8 kN of command,
and even though the station signals would read 8 kN of feedback,
the force standard may only read 4 kN. This shows the
conditioner/sensor pair are out of calibration.
