Application Notes Appendix B
Execute Pump Off Action
When a Pump Off condition exists, the drive follows the setting of P1189
[Pump Off Action]. The process starts over at Step 1
in this sequence
allowing five strokes to allow the pump to settle out.
Whenever the operator changes the base speed command, the process starts over
at Step 1
in this sequence.
When P1187 [Pump Off Config] is set to 2 “Cycle,” the full stroke torque is used
for pump off detection. A separate position counter is enabled, which uses the
gear ratio and speed feedback to create a position. The gear ratio must be set
correctly for this action to work.
• The position increments every 2 ms based on output frequency. The
torque is added to a buffer and a counter increments.
• When the position counter reaches 10,000, the counter is reset to 0. The
torque buffer is divided by the counter to create the average torque for the
cycle.
• This torque is the full cycle torque and is then used as the down stroke
torque was used in baseline set detection.
