If problems occur that are not identified in this manual, contact the nearest Yaskawa representative with this
information:
• Drive model
• Drive software version
• Date of purchase
• Description of the problem (for example failure conditions and modified parameters)

Table 7.1 Types of Faults, Minor Faults, Alarms, and Errors
Type Drive Response
Fault
When the drive detects a fault, it will cause these conditions:
• The keypad shows the fault code, and ALM/ERR stays illuminated.
• The drive shuts off output, and the motor coasts to a stop. Some faults let the user select a motor stopping method.
• The terminal set to H2-01 to H2-03 = E [MFDO Function Selection = Fault] will activate.
The drive will not operate until you clear the fault with a Fault Reset and the drive goes back to usual status.
Minor Faults/Alarms
When the drive detects a minor fault or an alarm, it will cause these conditions:
• The keypad shows the alarm code, and ALM/ERR flashes.
• The drive will continue to operate the motor. Some alarms let you select a motor stopping method.
• If the drive detects a minor fault, the terminal set to H2-01 to H2-03 = 10 [Alarm] will activate If you do not set
parameters H2-01 to H2-03, the drive will not trigger MFDO terminals if it detects a minor fault.
• The drive will not output a minor fault signal if it detects an alarm.
It is not necessary to do Fault Reset.
Operation Errors
An error occurs when parameter settings do not agree or a parameter combination is incorrect. The drive will not operate
until you set the parameters correctly.
When the drive detects an operation error, these conditions will result:
• The keypad shows the error code.
• Multi-function outputs do not output an alarm signal.
Find the parameters that caused the error and correct the settings.
Auto-Tuning Error
An error occurs during Auto-Tuning.
When the drive detects an operation error, it will cause these conditions:
• The keypad shows the error code.
• Multi-function outputs do not output an alarm signal.
• The motor coasts to stop.
Remove the cause of the error and do Auto-Tuning again.
Copy Function Error
An error occurs when you use the keypad for a backup, restore, or verify operation.
When the drive detects a copy function error, it will cause these conditions:
• The keypad shows the error code.
• Multi-function outputs do not output an alarm signal.
Push a key on the keypad to clear the error. Remove the cause of the error and try the backup, restore, or verify operation
again.
