This group contains parameters used for monitoring TR200 applications.
22-00 External Interlock Delay
Range:
0 s* [0 - 600 s]
22-2* No-Flow Detection
The adjustable frequency drive includes functions for detecting if the load conditions in the system allow the
motor to be stopped:
*Low Power Detection
*Low Speed Detection
One of these two signals must be active for a set time (par.22-24
place. Possible actions to select (par.22-23
No Flow Detection:
This function is used for detecting a no flow situation in pump systems where all valves can be closed. Can be
used both when controlled by the integrated PI controller in the adjustable frequency drive or an external PI
controller. The actual configuration must be programmed in par.1-00
Configuration mode for
- Integrated PI Controller: Closed-loop
- External PI Controller: Open-loop
