Application Notes Appendix B
Store Pump Cycle Torque
1. Verify the well is full.
2. Enter a command speed.
3. Start the Pump Jack from the HIM.
4. Set P1192 [Pump Cycle Store] to option 1 “Enable.”
If the Pump Off feature detects a pump jack torque signature waveform,
the waveform is stored and the parameter resets to 0 “Disabled.”
If this parameter does not reset to 0 “Disabled,” set P1187 [Pump Off
Config] to option 2 “Cycle.” In this mode the entire cycle torque is used as
the down stroke torque was used in the original pump off detection.
Setting top of stroke is not necessary in this mode.
Initialize Pump Stroke Position
1. Set P1193 [Set Top ofStroke] to option 1 “Enable.”
Use a Human Interface Module (HIM) to avoid any communication
delays.
2. Press enter when you visually see the Horsehead at the top position. This
action sets the stroke position to the stored pump cycle torque.
3. Stop the drive.
4. Set up DriveObserver with the following parameters.
•
P5 [Torque Cur Fdbk]
• P972 [Testpoint Lval]
• P1198 [Pct Cycle Torque]
• P1200 [Pct Drop Torque]
• P1201 [Stroke Pos Count]
