Check for a code or message displayed on the keypad if the drive or motor fails to operate.
If problems occur that are not covered in this manual, contact the nearest Yaskawa representative with the
following information:
• Drive model
• Software version
• Date of purchase
• Description of the problem (such as failure conditions)
The following table contains descriptions of the various types of faults, minor faults, alarms, and errors that may
occur while operating the drive.
If the drive is damaged, contact Yaskawa Electric Engineering Corporation. The contact information appears on

Table 6.1 Types of Faults, Minor Faults, Alarms, and Errors
The following state results when a fault is detected. The drive will remain inoperable until the
fault is cleared using Fault Reset and the drive returns to its normal state.
• When the drive detects an alarm, the alarm message is displayed on the keypad and
and ALM/ERR of the LED Status Ring begin flashing.
• The fault interrupts drive output and the motor coasts to a stop. Some faults allow the user to
select a stopping method with parameters when the fault occurs.
• Fault relay output MA-MC will turn ON, and MB-MC will turn OFF.
The following state results when a minor fault or alarm is detected. It is not necessary to
perform Fault Reset.
• When the drive detects a fault, the fault message is displayed on the keypad and
ALM/ERR of the LED Status Ring light continuously.
• Normally the drive continues running the motor. Some minor faults allow the user to select a
stopping method with parameters when the minor fault occurs.
• When the drive detects a minor fault, H2-xx = 10 [MFDO Function Select = Minor Fault]
will be ON. Terminals for which H2-xx has not been set will not output a signal even if the
drive detects a minor fault.
• A minor fault signal will not be output even if the drive detects an alarm.
An error occurs when parameter settings conflict or a parameter combination is incorrect. The
drive will not operate the motor until the parameters are set properly.
The following state results when an operation error is detected. Investigate the parameters that
caused the error, and correct the settings.
• The keypad displays a code indicating the specific error.
• Multi-function outputs do not output an alarm signal.
An error occurs while performing Auto-Tuning.
The following state results when a tuning error is detected. Remove the cause of the error and
perform Auto-Tuning again.
• The keypad displays a code indicating the specific error.
• Multi-function outputs do not output an alarm signal.
• The motor coasts to stop.
An error occurs when using the keypad for a backup, restore, or verify operation.
The following state results when an error is detected.
• The keypad displays a code indicating the specific error.
• Multi-function outputs do not output an alarm signal.
Pressing any key on the keypad will clear the error. Remove the cause of the error and try the
backup, restore, or verify operation again.
