Control Board Replacement Procedure
for Large Capacity G7 Drives
16. Upon successful auto-tuning, disable access to the factory level (A1-01=2) and clear the factory access
password (A1-04 = 0000).
17. Use the COPY function of the operator to paste the parameter settings from the old control board to the
new one. If the COPY function is unavailable, enter the previously recorded Modified Constants settings
manually (as recorded Step 1 above).
18. This completes the procedure.
Note: Contact your Yaskawa representative if any one of the following is true:
a. A motor cannot be connected.
b. The motor being used is two or more HP ratings smaller than the G7 (e.g. G7 = 150HP, Motor = 75HP).
The motor-drive size mismatch could result in improper tuning results.
c. The new control board software version does not match the old control board’s version.
