Figure 4.44 High Feedback Detection Inverse PID
Setting 1: Alarm
When feedback rises above the P1-11 for longer than the time set in P1-12, the digital output programmed to “High Feedback”
(H2-0o= 96) closes and the drive displays the “High Feedback – High FB Sensed” alarm.
When feedback falls below the level determined by P1-11 and P1-14, or when one or more of the conditions that enable high
feedback detection are no longer true, the digital output will open and the alarm will clear.
Setting 2: Digital out only
When feedback rises above the P1-11 for longer than the time set in P1-12, the digital output programmed to “High Feedback”
(H2-0o= 96) closes.
When feedback falls below the level determined by P1-11 and P1-14, or when one or more of the conditions that enable high
feedback detection are no longer true, the digital output will open.
n P2-01: Sleep Level Type
Selects which data source the drive will use to determine if it should activate the sleep function. This parameter is application-
dependent and should be set in conjunction with the type of system data is available. Choose the data type that best represents
a low-activity condition for the system.
Note: Set this parameter prior to changing other parameters related to the Sleep Function, as internal scaling is based on P2-01.
No. Parameter Name Setting Range Default
P2-01 Sleep Level Type 0 to 4 0
Setting 0: Output frequency
Setting 1: Output current
Setting 2: Feedback
Setting 3: Output speed (RPM)
Setting 4: Flow meter (requires flow meter)
n P2-02: Sleep Level
Sets the level at which the drive will enter sleep mode. The drive will enter sleep mode when the monitored data falls below
the P2-02 setting for the time set in P2-03.
No. Parameter Name Setting Range Default
P2-02 Sleep Level 0.0 to 6000.0 0.0 Hz
