22-01 Power Filter Time
Range:
Function:
0.50 s
*
[0.02 - 10 s] Set the time constant for the filtered
power readout. A higher value gives a
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]
Simplified The feedback is not detected. Only sleep speed
and time are checked.
This parameter is for sleep mode running in process close
loop mode. Use this parameter to configure whether to
detect the feedback for sleep mode.

Illustration 4.19 No-flow Detection
The frequency converter 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 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
•
Warning
•
Alarm
•
Sleep mode
