Try recovery factory default setting ifissue continues contact Distributornear you.MCU77 S-Flash Fault Warning External serial flash chip is broken. Contact Distributor near you. MCU80 FieldBus Fault Configurable Fault Loss of communication with BACnet IP, and thefieldbus reference is the remote reference OR thefieldbus control place is the remote control place.Check RS485 communication wiring.Verify drive parameter are set correctly.Check master programming to verifyproper addressing.MCU81 FieldBus Fault Configurable Fault Loss of communication with SA Bus, and the fieldbusreference is the remote reference OR the fieldbuscontrol place is the remote control place.Check RS485 communication wiring.Verify drive parameter are set correctly.Check master programming to verifyproper addressing.MCU82 Bypass Overload Fault Over load when motor is in bypass mode Check motor connection situation MCU83 FieldBus Fault Configurable Fault Loss of communication with Modbus RTU, and thefieldbus reference is the remote reference OR thefieldbus control place is the remote control place.Check RS485 communication wiring.Verify drive parameter are set correctly.Check master programming to verifyproper addressing.MCU84 FieldBus Fault Configurable Fault Loss of communication with Modbus TCP, and thefieldbus reference is the remote reference OR thefieldbus control place is the remote control place.Check Ethernet communication wiring.Verify drive parameter are set correctly.Check master programming to verifyproper addressing.MCU85 FieldBus Fault Configurable Fault Loss of communication with BACnet, and The fieldbusreference is the remote reference OR The fieldbuscontrol place is the remote control place ,and Thefault protection is not “NO action”Check RS485 communication wiring.Verify drive parameter are set correctly.Check BACnet master configurationprogramming to verify properaddressing.MCU86 FieldBus Fault Configurable Fault Loss of communication with Ethernet IP, and Thefieldbus reference is the remote reference OR Thefieldbus control place is the remote control place ,andThe fault protection is not “NO action”Check Ethernet communicationwiring. Verify drive parameter areset correctly. Check EIP masterconfiguration programming to verifyproper addressing.MCU87 FieldBus Fault Configurable Fault Loss of communication with Profibus/Canopen/Devicenet master on Slot A, and The fieldbusreference is the remote reference OR The fieldbuscontrol place is the remote control place ,and Thefault protection is not “NO action”Check Profibus/Canopen/Devicenetcommunication wiring. Verify driveparameter are set correctly. CheckProfibus/Canopen/Devicenet masterconfiguration programming to verifyproper addressing.MCU88 FieldBus Fault Configurable Fault Loss of communication with Profibus/Canopen/Devicenet master on Slot B, and The fieldbusreference is the remote reference OR The fieldbuscontrol place is the remote control place ,and Thefault protection is not “NO action”Check Profibus/Canopen/Devicenetcommunication wiring. Verify driveparameter are set correctly. CheckProfibus/Canopen/Devicenet masterconfiguration programming to verifyproper addressing.MCU89 Under VoltageStopFault The DC link voltage has reached the Drive undervoltage stop limit value.In case of temporary supply voltagebreak reset the fault and restart theAC drive Check the supply voltage.If it is adequate, an internal failurehas occurred. Contact the distributornear youDSP90 Drive UnderTempWarning/Fault • Cold weather mode is not enabled, and unittemperature is less than -10 degree.• Cold weather mode is enabled and Under TempFault Override is not set, unit temperature is lessthan -30 degree.• Cold weather mode is enabled and Under TempFault Override is not set, unit temperature is -20~-30 degree. The temp <-20 degree when coldweather start time out.If unit temp -20 ~ -10 degree, startmotor in cold weather mode.If unit temp <-20 degree, Warm up unitabove -20deg C for proper operationusing cold weather mode.If still < -20degree when cold weather mode timeout, try higher output voltage in coldweather mode.DSP
