Display
Sleep activates when selected level (P2-01) reaches programmed sleep
level for time specified in P2-03. The level type is determined by
P2-01. A value of 0 disables this function. This function is only active
during running while operating in auto mode.
If P1-01 = 3, the function is active when there is only one drive running on
the network.
<0034>
Display Units for Sleep Level P2-02 when P2-01 is programmed for the
following:
P2-01=0: Display based on "Hz"
P2-01=1: Display based on "A"
P2-01=2: Display based on P1-02 Selection
P2-01=3: Display based on "rpm"
P2-01=4: Display based on P6-02 Selection
Note: When P2-01 is set for a value of 2, display units will be dependent
on P1-02 setting. If P2-02 = 0, pump will sleep at minimum speed.
Delay time before drive enters sleep mode when criteria is met as defined
by parameter P2-02.
When the drive enters sleep mode, the software monitors the feedback to
detect a flow-no flow condition. If the PID Error (setpoint minus feedback)
exceeds the programmed level P2-04 within the programmed time (P2-05)
and the output frequency is greater than the minimum frequency (P1-06),
the sleep operation deactivates and the drive returns to normal operation. A
value of 0 disables this function.
Defines the time window in which the software monitors the feedback to
detect a flow-no flow condition. Works in conjunction with parameter P2-
04.
Maximum number of cycles allowed within the time specified in P2-07
before the drive initiates a "Pump Cycle Fault (PCF)". One Cycle is
defined when the drive transfers from normal operation in auto mode to
sleep mode. A value of 0 disables this function.
If P1-01 = 3, the function is active when there is only one drive running on
the network.
<0034>
Maximum time allowed between cycles. When no cycling occurs within
the programmed time, the drive will reset the internal cycle register. Works
in conjunction with P2-06.
Sets the Over Cycle Mode:
0: Disabled
1: Alarm
2: Pump Over Cycle Fault (POC)
3: Auto Compensation
Allows for the software to automatically compensate the setpoint in case of
excessive cycling.
Maximum allowable setpoint compensation for the over-cycling function.
When the motor rpm falls below the programmed level in P2-12, the no-
flow detection will activate. A value of 0 disables this function.
If P1-01 = 3, the function is active on the lead drive.
Sets the motor rpm fluctuation bandwidth. No-flow activates when the
motor rpm remains within the programmed bandwidth in P2-12 for a time
specified in parameter P2-13.
No-flow activates when the motor rpm remains within the programmed
bandwidth (P2-12) for a time specified in parameter
P2-13.
Time delay when setpoint returns to the original setting after being
changed for no-flow detection.
