YASKAWA GPD315/V7-4X - 5.29 Copy Function

5-46
The standard digital operator JVOP-140 of the GPD 315/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 GPD 315/V7-4X (NEMA 4). 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 GPD315/V7 to a GPD305/J7
(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
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.
