Drive Alarms, Faults, and Errors

u

Types of Alarms, Faults, and Errors

Check the LED operator for information about possible faults if the drive or motor fails to operate.
LED Operator on page 58.
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
Table 6.3 contains descriptions of the various types of alarms, faults, and errors that may occur while operating the drive.
Contact Yaskawa in the event of drive failure.
Type
When the drive detects a fault:
• The digital operator displays text that indicates the specific fault and the ALM indicator LED remains lit until the fault is
reset.
• The fault interrupts drive output and the motor coasts to a stop.
Faults
• Depending on the setting, the drive and motor may stop via different methods than listed.
• If a digital output is programmed for fault output (H2-01 = E), it will close if a fault occurs.
When the drive detects a fault, it will remain inoperable until that fault has been reset.
146.
When the drive detects an alarm or a minor fault:
• The digital operator displays text that indicates the specific alarm or minor fault and the ALM indicator LED flashes.
• The motor does not stop.
Minor Faults and
Alarms
• The multi-function contact output closes if set to be tripped by a minor fault (H2-01 = 10), but not by an alarm.
• The digital operator displays text indicating a specific alarm and ALM indicator LED flashes.
Remove the cause of an alarm or minor fault to automatically reset.
When parameter settings conflict with one another or do not match hardware settings (such as with an option unit), it results
in an operation error.
When the drive detects an operation error:
• The digital operator displays text that indicates the specific error.
Operation Errors
• The multi-function contact output does not operate.
When the drive detects an operation error, it will not operate the motor until the error has been reset. Correct the settings that
caused the operation error to reset.

Alarm and Error Displays

n Faults
When the drive detects a fault, the ALM indicator LEDs remain lit without flashing. If the LEDs flash, the drive has detected
a minor fault or alarm. Refer to Minor Faults and Alarms on page 132
or external faults can trip both faults and minor faults, therefore it is important to note whether the LEDs remain lit or if the
LEDs flash.
