● 6: OE-3, means overvoltage happens when deceleration
● 7: OL-1, means frequency converter overload
● 8: OL-2, means motor overload
● 9: EEP-, read/write EEP error, when read and write EEP/flash, error happens
● 10: SPI-, internal communication error
● 11: E-St, external fault
● 12: RS-, external communication error
● 13: CF, circuit fault, when there is something wrong with current detection
● 14: Reserved
● 15: OT, motor over temperature
● 16: CPU-, CPU is disturbed by external signal and program run to illegal address
● 17: SC, short circuit of IGBT happens
● 18: IPHL, input phase loss
● 19: OPHL, output phase loss
● 20: OH, frequency converter over temperature
● 21: PRSE, parameter set error
