Control Circuit Error
Cycle control power to the drive.
⇒If the problem continues, replace the control board. For instructions on replacing it,
contact Yaskawa or your nearest sales representative.
⇒Replace the operator.
A/D Conversion Error
An A/D conversion error or control circuit error occurred.
Cycle control power to the drive.
⇒If the problem continues, replace the control board. For instructions on replacing it,
contact Yaskawa or your nearest sales representative.
EEPROM Memory Data Error
There is an error in the data saved to EEPROM.
Cycle control power to the drive.
⇒If the problem continues, replace the control board. For instructions on replacing it,
contact Yaskawa or your nearest sales representative.
⇒Reinitialize the drive (A1-03 = 2220).
Hybrid IC Error
• Cycle control power to the drive.
• If the problem continues, replace either the control board or the entire drive. For instructions
on replacing the control board, contact Yaskawa or your nearest sales representative.
Control Board Connection Error
Connection error between the control board and the Power Cell
• Turn off the power for the main circuit and controls and check the connection between the
control board and the Power Cell.
• If the problem continues, replace either the control board or the entire drive. For instructions
on replacing the control board, contact Yaskawa or your nearest sales representative.
Control Circuit Error
⇒Replace the cell control board. For instructions on replacing it, contact Yaskawa or your
nearest sales representative.
Speed Deviation (for Control Mode with PG)
The deviation between the speed reference and speed feedback is greater than the setting in
F1-10 for longer than the time set to F1-11.
Check the size of the load.
⇒Reduce the load.
⇒Increase the acceleration and deceleration times (C1-01 through C1-08).
⇒Check the machine.
⇒Check the settings of parameters F1-10 and F1-11.
⇒Ensure the motor brake releases properly.
