Explanation of functions (parameters)

Changingexample Changing the calibration parameter C4 "frequency setting voltage gain" value

POINT

The calibration parameter C4 is an extended function parameter. Pr. 30 must be set to "1".

(2)Adjusting a deviation of the highest frequency from the Pr. 38 (Pr. 39) setting.

(2)-1 Making adjustment with a voltage applied directly across terminals 2-5 (with a current flowing across terminals 4-5)

OperationDisplay

1.Confirm the RUN indication and operation mode indication.

The inverter must be at a stop.

The inverter must be in the PU operation mode.

The calibration parameter C1 "AM terminal calibration" value must be set. (For the setting method, refer to the instruction manual (basic).)

When write is performed, an error ( ) is displayed.

The gain and bias frequency settings are too close.
