7.2 Types of Faults, Minor Faults, Alarms, and Errors
If the drive or motor do not operate correctly, check the drive keypad for a code or message.
If problems occur that are not identified in this manual, contact the manufacturer with this information:
•
Drive model
•
Drive software version
•
Date of purchase
•
Description of the problem (such as failure conditions)
Contact the manufacturer if there is damage to the drive.
The following table contains descriptions of the different types of faults, minor faults, alarms, and errors that can
occur during drive operation.
Table 7.1 Types of Faults, Minor Faults, Alarms, and Errors
Type Drive Response
Faults
When the drive detects a fault, it will cause these conditions:
•
The keypad shows the fault code and illuminate continuously.
•
The drive shuts off output, and the motor coasts to a stop. Some faults let the user select a motor stopping method.
•
Fault relay output 1NO-1CM will turn ON, and 1NC-1CM will turn OFF.
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 flash.
• The drive will continue to operate the motor. Some alarms let the user select a motor stopping method.
• If the drive detects a minor fault, the terminal set to H2-01 to H2-03 = 4 [Multi-Function Digital Output 1 to Multi-
Function Digital Output 3 = Alarm] will switch ON. If you do not set parameters H2-01 to H2-03 , the drive will not
trigger MFDO terminals when it detects a minor fault.
•
The drive will not output a minor fault signal when 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 Errors
An error occurs during Auto-Tuning.
When the drive detects a tuning 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 Errors
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.
