Faults and Alarms

Look at the drive keypad for fault and alarm information if the drive or motor do not operate correctly.
For drive alarms:
• Keypad shows the alarm code
•
and ALM/ERR on the LED Status Ring flash.
• The drive will continue to operate the motor. Some alarms let the user select a motor stopping method.
For drive faults:
• Keypad shows the fault code
• and ALM/ERR on the LED Status Ring stay illuminated.
• The drive shuts off output, the fault relay output turns ON, and the motor coasts to stop.
