Denotes that parameter can be changed when the drive is running.
Note 1: When P1-02 = 3, parameter P1-03 must be set to (120 x E1-04/E2-04) for proper display. When P1-02 = 14, parameter P1-03 must be set to the same value as E1-
04 for proper display.

Scaling of feedback device in user units (P1-02=1, e.g. 150 psi).
Digits 1 through 4 set the maximum feedback number. Digit 5 determines
the number of decimal places.
Digit 5 = 0: Number format is XXXX
Digit 5 = 1: Number format is XXX.X
Digit 5 = 2: Number format is XX.XX
Digit 5 = 3: Number format is X.XXX
Examples:
01000 = 1000
13000 = 300.0
25000 = 50.00
32000 = 2.000
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.
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.
<0034>
Drive starts when the feedback level drops below the start level for a time
specified in P1-05.
Minimum drive frequency when operated in the auto mode. Programmed
value will limit minimum PID output. Minimum value must be
programmed to a value smaller than P3-09 and P3-10 when drive is
operating in the multiplex mode (P1-01).
The drive will display a "Low Feedback (LFB)" alarm when the feedback
level falls below the programmed level. The alarm will turn off when the
feedback level rises above the programmed Low Feedback Level plus the
Hysteresis Level (P1-13). A value of 0 disables this function. This function
is only active during running while operating in the auto mode.
The drive will display a "Low Feedback/Water (LFB/LW)" alarm when the
feedback level falls below the programmed level for a time specified in P1-
08. The drive will coast to a stop when a fault occurs. A value of 0 disables
this function. This function is only active during running while operating
in the auto mode.
If P1-01 = 3, the function will stop all drives running on the network when
the system fault occurs.
