MG.02.C2.02 - VLT
Function:
Select input to function as feedback signal.
Function:
Feedback larger than setpoint result in a speed reduction.
Feedback less than setpoint result in a speed increase.
Feedback larger than setpoint result in a speed increase.
Feedback less than setpoint result in a speed reduction.
Function:
Regulation of a given error will continue even when the output
frequency cannot be increased/decreased.
PI-controller ceases from regulating a given error when the out-
put frequency cannot be increased/decreased.
Function:
Until the set motor speed has been reached the frequency con-
verter operates in Open Loop mode.
Function:
Enter the value for the P proportional gain, i.e. the multiplication
factor of the error between the set point and the feedback sig-
nal.
Note! 0.00 = Off.
