8.4 INQUIRY FOR FAILURE RECORD
This series of frequency inverter records the failure code for the recent 8 times and the output parameters of
frequency inverter for the last failure. Looking up such information can help find the reasons of failure.
The failure information and status monitoring parameters are stored uniformly. Please look up the information
referring to operating methods of keyboard.
