When
No Flow Mode [IO–38]

, the flow switch will become an additional condition for sleep
mode. When VFD runs with PID control and determines that all sleep mode conditions are met and the flow
switch is open during Sleep delay, VFD will go into sleep mode.
Broken Pipe Protection (for Pump Applications)
The VFD has the ability to detect a broken pipe in the system. The VFD must be running with PID Control in
Auto mode for this feature to be active.
To enable this feature, adjust the following parameters:
Broken Pipe Level [SET–36]:
0.0 to
PID F/B Max [SET–20]
. Setting of 0.0 disables the feature. When pressure
falls below this level and VFD continues to run above
Broken Pipe Freq [SET–37]
,
Broken Pipe Delay [SET-38]
starts.
Broken Pipe Freq [SET–37]:
PID Low Hz Limit [SET–22]
to
PID Hi Hz Limit [SET–23]
.
Broken Pipe Delay [SET–38]:
The timer provide a delay for triggering a Broken Pipe fault.
NOTE:
Manual or remote reset is required.

-
eters
OCA Level [PROT-07]
(at acceleration) and
OCN Level [PROT-08]
(at steady speed).
When motor current reaches Stall level either during acceleration or at steady speed, VFD will decrease out
