P3-13 Friction Compensation Start Frequency
■
Setting Range:
0.0 to 120.0 Hz
Factory Default: 0.0 Hz
The iQpump drive can be configured for multiplex pumping operation. The pump system may experience an increase of friction when
additional pumps are staged (turned ON). The level when the additional compensation for friction losses can be programmed into the
Friction Compensation Start Frequency (P3-13). This function will activate when the output frequency rises above the Friction
Compensation Start Frequency (P3-13). The maximum compensation at Maximum Output Frequency (E1-04) is specified by the
Maximum Friction Increase at Maximum Frequency (P3-14).
The Friction Compensation Start Frequency (P3-13) works in conjunction with the Maximum Friction Increase at Maximum Frequency
(P3-14).
Note: This function is only active when the Pump Mode (P1-01) is set to 0.
