◆ P1-05 Start Level Delay Time
Setting Range: 0 ~ 3600 s
Factory Default: 1 s
The iQpump drive can be configured to prevent the pump from starting for a set period of time by programming the Start Level Delay
Time (P1-05) after an Auto Mode run has been initiated.
If this parameter is set to a non-zero value and a run command is present within 1 second of power being applied to the drive, the start of
the drive will be delayed. Presumably, multiple drives fed off of the same utility feed would have their timers set to different times.
Note: The Start Delay Time will function only after a stop command due to the no-flow detection or sleep detection functions.
Removing the enable signal does not activate the Start Delay.
Important: Please refer to the Pump Protection (P2 Group on page 155 ) and Pump Multiplex section (P3 Group on page 172 ) for further
details and timing diagrams.
Table 54 Related Parameters <0034>
◆ P1-06 Minimum Pump Frequency
Setting Range: 0 ~ 120 Hz
Factory Default: 40 Hz
The iQpump drive can be configured to operate the pump at a minimum output frequency by programming the Minimum Pump
Frequency (P1-06). The minimum value has to be programmed to a value smaller than Pump 2 Frequency Shutdown Level (P3-09) and
Pump 3 Frequency Shutdown Level (P3-10), when the drive is operating in the Multiplex Mode (P1-01). The programmed value in P1-06
will also limit the minimum PID output. If the Thrust Bearing Frequency (P4-05) is programmed for a value greater than 0, then the
minimum frequency is determined by the Thrust Bearing Frequency (P4-05).
Important: Please refer to the Pump Protection (P2 Group on page 155 ) and Pump Multiplex section (P3 Group on page 172 ) for further
details and timing diagrams.

Start Level
Start Level
Drive starts when the feedback level drops below the start level for a
time specified in P1-05. This level also specifies the wake up level
when the drive is in Sleep Mode.
If set to a negative value, the feedback level must drop by this amount
below the setpoint.
<0034>
Note: When PID operates in the reverse mode, the feedback value
has to rise above the start level for the time programmed in P1-05 for
the system to start. A value of 0 disables this function.
If P1-01 = 3, the function is active only on the first drive in the
network.
