Yaskawa V7 Drives - Manual (Page 98)

5-46
The standard digital operator JVOP-140 of the V7 can be used to store (upload) parameters from one
drive, and copy (download) parameters to another drive. The copy function is not available on the
V74X. Parameters are stored in an EEPROM on the digital operator therefore no backup power supply
is necessary. The copy function can be used in most cases except the following.
(1) Different drive types – The user may not copy parameters from a V7 to a J7 drive.
(2) Different voltage class – The user may not copy parameters from a 230V drive to a 460V drive.
(3) Different control mode – The user may not copy parameters from a drive operating in the Volts per
hertz mode (n002=0) to a drive in the Open loop vector mode (n002=1).
The following parameters are not copied when capacities are different.

Parameters n176, n177, n178 and n179 are not read into the digital operator during a read command.
n176: Parameter Copy Function Selection
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
uFy Verify that parameters stored in the Digital Operator and the drive are the same
uA 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
n177: P arameter Copy Access Selection
The Copy Function can be enabled or disabled using parameter n177 – parameters cannot be
uploaded when this parameter is disabled ( n177 = 0), preventing the accidental overwriting of
parameters stored in the Digital Operator.
If n177 = 0 and an upload is attempted (n176 = rEd or Cpy), a "PrE" error message will blink on the
Digital Operator display – press DSPL or DATA/ENTER to clear the message.
