5.12 Troubleshooting
The HAV-SP series drive provides rich fault handling information. When the drive fails, the
keypad will display the fault code and stop output. The fault record parameter group U1 can record
the last 10 fault information. After the fault occurs, the processing steps are as follows:
1. When the drive fails, check whether the keypad display is abnormal? If yes, seek for
service;
2. If there is no abnormality, please check the group U1 function code, confirm the
corresponding fault record parameters, and determine the actual status at occurrence of the current
fault through all parameters;
3. Check the fault alarm content and countermeasure table, and check whether there is a
corresponding abnormal status according to the specific countermeasures?
4. Do troubleshooting or ask relevant personnel for help;
5. After confirming the troubleshooting, reset the fault and start running.
