Total setpoint compensation can be monitored with Total Setpoint Compensation (U1-93).
◆ P2-09 Setpoint Compensation
Setting Range: 0.0 ~ 6000.0
Factory Default: 0.0
The iQpump drive can automatically increase the setpoint each time the maximum number of cycles programmed in Sleep Mode:
Cycling Protection (P2-06). The units for this parameter are determined by the System Units (P1-02).
Refer to Over-Cycling Mode: (P2-08 = 3: Auto Compensation) for more details.
◆ P2-10 Maximum Setpoint Compensation
Setting Range: 0.0 ~ 6000.0
Factory Default: 0.0
The iQpump drive can set the maximum allowable setpoint compensation during an over-cycling condition by the value programmed in
Maximum Setpoint Compensation (P2-10). The units for this parameter are determined by the System Units (P1-02).
Refer to Over-Cycling Mode: (P2-08 = 3: Auto Compensation) for more details.
◆ P2-11 No-Flow Activation Level
Setting Range: 0 ~ 24000 rpm
Factory Default: 0 rpm
The iQpump drive can be configured to activate a no-flow detection by programming the No-Flow Activation Level (P2-11). The no-flow
detection is active when the motor is operating below this No-Flow Activation Level (P2-11) and below the No-Flow Detection
Bandwidth (P2-12).
Setting P2-11 to a value of 0 will disable this function. This function is only active during operation in the Auto Mode and when the drive
is operating above the Minimum Pump Frequency (P1-06) and below the level programmed in P2-11.
Note: Program Start Level (P1-04) to a value greater than 0.
The No-Flow Activation Level (P2-11) works in conjunction with the No-Flow Detection Bandwidth (P2-12).
If P1-01 = 3, the function is active on the lead drive.
