3.15.1 22-0* Miscellaneous
Parameter group for extra settings.
22-01 Power Filter Time
Range: Function:
0.50 s* [0.02 - 10 s] Set the time constant for the ltered
power readout. A higher value gives a
22-01 Power Filter Time
Range: Function:
more steady readout but a slower system
response to changes.
22-02 Sleepmode CL Control Mode
Option: Function:
[0] Normal The feedback is detected. Some parameters are
checked.
[1] Simplied The feedback is not detected. Only sleep speed
and time are checked.
This parameter is for sleep mode running in process
closed-loop mode. Use this parameter to congure
whether to detect the feedback for sleep mode.

Illustration 3.16 No-ow Detection
The frequency converter includes functions for detecting if the load conditions in the system allow the motor to be
stopped:
•
Low power detection.
One of these 2 signals must be active for a set time (parameter 22-24 No-Flow Delay) before selected action takes place.
Possible actions to select (parameter 22-23 No-Flow Function):
•
No action
•
