Possible Solutions
For CANopen communication, set F6-35
[CANopen Node ID Selection] correctly.
Correct any wiring errors.
• Repair short circuits and connect cables.
• Replace the defective communications cable.
Examine communications at start-up and correct
programming errors.
• Do a self-diagnostics check.
• If the problem continues, replace the control
board or the drive. For information about
replacing the control board, contact Yaskawa or
your nearest sales representative.
On the last drive in a MEMOBUS/Modbus
network, set DIP switch S2 to the ON position to
enable the termination resistor.
Correct any wiring errors.
• If these errors occur, the object dictionary will be
reset to its default values. After the object
dictionary has been changed and object
dictionary contents are then changed, execute a
Store Parameter command (Index = 1010 (Hex)).
• If the object dictionary has not been changed,
execute a Restore Parameter command (Index =
1011 (Hex)).
Check communications at start-up and correct
programming errors.
• Perform a self-diagnostics check.
• 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.
