Chapter 5 ParametersVFD-S Series

This parameter selects the operation of the drive upon a loss of PID feedback signal.

Settings

d0.0 to d650 seconds

Factory Setting: d0.0

 

 

 

 

These parameters determine sleep functions of the AC drive. If the command frequency falls

below the sleep frequency, for the specified time in Pr. A-12, then the drive will shut off the output and wait until the command frequency rises above Pr. A-11. Please see the below diagram.

When parameter A-13 is set to 0, what F and H display is the actual value of setting frequency and output frequency. When this parameter is not set to 0, the display value of F and H = actual value ¯A-13/1-00. To set frequency with panel, communication, VR, AVI or ACI need to set according to the display value. For example, when 1-00=60.0Hz, if A-13 is set to 30.0 Hz, it means when the actual value of frequency is 30.00 Hz, the display value will be 15.0 Hz . If you want to let drive run at 10.0Hz, the frequency command must be 5.0 Hz. But
