Sets the scaling of feedback device in user-set units.
FB Dev. Scaling
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,
Start-DrawDn Lvl
Pump Mode, is set to 3 (MEMOBUS network), this function is
active only on the first drive in the network.
Note:
The system starts when the feedback level drops below the start
level for the time set in this parameter.
Minimum frequency at which the drive will run. Applies to both
HAND and Automatic modes.

Low FB Level
Description
<1>
<2>
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.
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).
Changing this parameter will reset the P1-06
default value.
