Yaskawa J7 Drive - Manual (Page 73)

5-38
The optional Remote Digital Operator can be used to store (upload) parameters from a drive, which
can then be copied (downloaded) to another drive. These parameters are stored in EEPROM in the
Digital Operator. The Copy Function is possible only for drives of the same type (i.e. from one J7 to
another, but not from a J7 to a V7 or vice versa), and voltage rating (230V drive or 460V drive). In
addition, the following parameters cannot be copied:
5.27 COPY FUNCTION
Parameter No. Parameter Name
n09 to n15 V/f Settings
n32 Motor Rated Current
n46 Carrier Frequency
n64 Motor Rated Slip
n65 Motor No-load Current
n76 : Parameter Copy Function Selection Ex : Factory Setting: rdy
Setting Description
rdy Drive is ready to use Copy Function
rEd Read (or upload) all parameters from the drive and store them in the Digital Operator
Cpy Copy (or download) all parameters stored in the Digital Operator to the drive
vFy Verify that parameters stored in the Digital Operator and the drive are the same
vA Displays the voltage and kW rating of the drive whose parameters are stored in the
Digital Operator
Sno Displays the software number of the drive whose parameters are stored in the
Digital Operator
n77 : Parameter Copy Access Selection Factory Setting: 0
Range: 0 or 1
Setting Description
0 Copying Disabled
1 Copying Allowed
The Copy Function can be enabled or disabled using parameter n77 – parameters cannot be
uploaded or downloaded when this parameter is disabled (n77 = 0), preventing the accidental
overwriting of parameters stored in either the Digital Operator or the Drive.
If n77 = 0 and an upload or download is attempted (n76 = rEd or Cpy), a “PrE” error message will
blink on the Digital Operator display – press DSPL or DATA/ENTER to clear the message.
