Feedback Device
Scaling
FB Dev. Scaling
Sets the scaling of feedback device in user-set units.
Default: 145.0
PSI
Min.: 0.1
Max.: 6000.0
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.
Min.: 0.0
Max.: 999.9
P1-05
(0C02) Start Level Delay Time S-Lev Delay Time
The system starts when the feedback level drops below the start
level for the time set in this parameter.
Default: 1 s
Min.: 0
Max.: 3600
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).
Min.: 0.0
Max.: [E1-04]
