Table 2.1 Types of Faults, Minor Faults, Alarms, and Errors
When the drive detects a fault, it will cause these conditions:
• The keypad shows the fault code and
• 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 MA-MC will turn ON, and MB-MC 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.
When the drive detects a minor fault or an alarm, it will cause these conditions:
• The keypad shows the alarm code and
• 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 = 10 [MFDO Function Select = 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.
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.
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.
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.
