P1-04
(0C03)
Start / Draw Down
Level
Start-DrawDn Lvl
The system starts when the feedback level drops below the start
level for the time set in P1-05. This level also specifies the wake-
up level when the drive is in Sleep Mode.
When this parameter is set to a negative value, the feedback level
must drop that amount below the setpoint.
Setting this parameter to 0.0 disables the function. When P1-01,
Pump Mode, is set to 3 (MEMOBUS network), this function is
active only on the first drive in the network.
Note: When PID operates in reverse mode, the system
will start when the feedback has risen above the
start level for the time set to P1-05.
Default: 0.0
Min.: -999.9
Max.: 999.9

P1-06
(0C05)
Minimum Pump Speed Min. Pump Speed
Minimum frequency at which the drive will run. Applies to both
HAND and Automatic modes.
Note: For minimum pump frequency, the drive will use
the highest setting from among P1-06, P4-12
(Thrust Bearing Frequency), or d2-02 (Reference
Lower Limit).
Default: 40.0 Hz

P1-09
(0C08)
Low Feedback Level
Fault Delay Time
Low Lvl FLT Time
Sets the amount of delay time from when the low feedback is
detected until the drive faults on an “LFB Low Feedback” fault.
Note: 1. This parameter is effective only when P1-10
is set to 0 (Fault).
2. When P1-01 is set to 3, parameter P9-18 uses
this value to calculate the quick de-stage
feedback level.
Default: 10 s
Min.: 0
Max.: 3600
