680 [Pump Cycle Store]
Used to store the torque waveform over the course of a
pump cycle. This is used to determine the downstoke when
in “Automatic” or “Position” mode.
With the drive running at the desired speed, change [Pump
Cycle Store] to “Enabled” and press enter. Over the next few
cycles the waveform is stored and [Pump Cycle Store]
changes back to “Disabled”.
If after 5 pump cycles [Pump Cycle Store] has not changed
back to “Disabled”, waveform variations can be excessive.

“Baseline Set”
“Fixed Setpt”
“Disabled” (0) - Pump Off control is not active.
“Baseline Set” (1) - The control uses a torque baseline created after any start of the drive (first ten cycles).
IMPORTANT: It is critical that this data is gathered from a full well.
“Fixed Setpt” (2) - The control uses the value in [Torque Setpoint]. Use the value in [% Drop Torque] as a
guideline in “Automatic” or “Position” mode. In “Cycle” mode use [% Cycle Torque] as a guideline.
