Torque Curve
The torque curve routine gives important information on the actuator working conditions
in comparison with a previously memorized reference torque curve. It can be used to
perform a detailed analysis of a change in the process conditions.
During a full valve stroke in opening or closing, the F01-2000 measures the torque
values relevant to every 1% of position variation. At the end of the stroke the collected
101 values (one torque value every 1% of position change) are saved in the F01-2000
memory together with the time and date of strokes, main voltage, motor temperature,
temperature inside the electronics compartment and temperature inside the terminal
board compartment. Up to 100 curves in opening and 100 curves in closing can be saved.
When a new curve is available the oldest one is cancelled and the new one is memorized.
The above data are updated at the end of every full valve stroke. Data relevant to a partial
stroke are discharged. Function “set curve reference”, in the SET-UP MENU, Maintenance,
Section 7, allows to save the full set of data relevant to 1 off 100 “torque curves” in the
“torque curve reference”. The “torque curve reference” will not be updated until a new “set
curve reference” command is entered.
The user can compare the last 100 torque curves in opening and closing relevant to the last
200 valve strokes with the torque curve reference saved before.
Table 13 shows the list of saved data for each opening or closing curve:
Date
Date of the valve stroke
Time
Time of the valve stroke
Temperature
Temperature (°C) inside the terminal board compartment during
the valve stroke
Term temp
Temperature of the electrical motor (°C) during the valve stroke
Motor temp
Main voltage supply (V) during the valve stroke
Main voltage
Monitor relay conditions, ASi conditions, contact action
Closing / Opening time
Torque 0
Torque value in % of the nominal torque / thrust stated in the
nameplate menu. In opening “Torque 0” corresponds to position
0% and in closing “Torque 0” corresponds to position 100%
Torque 100
Torque value in % of the nominal torque / thrust stated in the
nameplate menu. In opening “Torque 100” corresponds to position
100% and in closing “Torque 100” corresponds to position 0%
