Yaskawa J7 Drive - Manual (Page 82)

A1-1
The Drive control circuits use various parameters to select functions and characteristics of the Drive.
Changing of parameter settings must be done in the Program mode, or by use of the Function
LEDs, if available (see Section 4).
The following table lists all parameters in numerical order. For each parameter, reference
paragraph(s) in Section 5 are listed (if applicable) where the features of the Drive affected by that
parameter are described.
