65 Replace Fan Configurable Warning Fan life is less than 2 months Check the fan, clean out any
contamination, contact distributor near you
for replacement fan.
66 Safety Torque Off Fault STO Triggered, STO input is open. Reset STO Trigger and verify wiring. Reset
fault after input is enabled.
67 Current Limit Control Warning The output current has reached the current
limit value
Check the load
Set the acceleration time longer
68 Over Voltage Control Warning The DC link voltage has reached its voltage
limit value
Check the input voltage
Set the acceleration/deceleration time
longer
69 System Fault Fault Thermistor SPI communication error. Check thermistor chip.
70 System Fault Fault MCU send wrong parameters to DSP. Restart the drive again. Should the fault
re-occur, contact the distributor near you.
80 FieldBus Fault Configurable Fault Loss of communication with BACnet/IP, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place
Check RS-485 communication wiring.
Verify drive parameters are set correctly.
Check master programming to verify proper
addressing.
81 FieldBus Fault Configurable Fault Loss of communication with SA Bus, and the
fieldbus reference is the remote reference OR
the fieldbus control place is the remote
control place
Check RS-485 communication wiring.
Verify drive parameters are set correctly.
Check master programming to verify proper
addressing.
82 Bypass Overload Fault Over load when motor is in bypass mode Check motor connection situation
83 FieldBus Fault Configurable Fault Loss of communication with Modbus RTU, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place
Check RS-485 communication wiring.
Verify drive parameters are set correctly.
Check master programming to verify proper
addressing.
84 FieldBus Fault Configurable Fault Loss of communication with Modbus TCP, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place
Check Ethernet communication wiring.
Verify drive parameters are set correctly.
Check master programming to verify proper
addressing.
85 FieldBus Fault Configurable Fault Loss of communication with BACnet, and the
fieldbus reference is the remote reference OR
the fieldbus control place is the remote
control place, and the fault protection is not
“NO action”
Check RS-485 communication wiring.
Verify drive parameters are set correctly.
Check BACnet master configuration
programming to verify proper addressing.
86 FieldBus Fault Configurable Fault Loss of communication with EtherNet/IP, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place, and the fault protection is not
“NO action”
Check Ethernet communication wiring.
Verify drive parameters are set correctly.
Check EIP master configuration
programming to verify proper addressing.
87 FieldBus Fault Configurable Fault Loss of communication with Profibus/
CANopen/DeviceNet master on Slot A, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place, and the fault protection is not
“NO action”
Check Profibus/CANopen/DeviceNet
communication wiring. Verify drive
parameter are set correctly. Check
Profibus/CANopen/DeviceNet master
configuration
programming to verify
proper
addressing.
88 FieldBus Fault Configurable Fault Loss of communication with Profibus/
CANopen/DeviceNet master on Slot B, and
the fieldbus reference is the remote reference
OR the fieldbus control place is the remote
control place, and the fault protection is not
“NO action”
Check Profibus/CANopen/DeviceNet
communication wiring. Verify drive
parameter are set correctly. Check
Profibus/CANopen/DeviceNet master
configuration programming to verify proper
addressing.
89 Under Voltage Stop Fault The DC link voltage has reached the Drive
under voltage stop limit value.
Check the input voltage.
