Fault
code Fault Name Fault Type Default Possible Cause Remedy Realization
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 RS485 communication wiring.
Verify drive parameter are set correctly.
Check master programming to verify
proper addressing.
MCU
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 parameter are set correctly.
Check master programming to verify
proper addressing.
MCU
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 RS485 communication wiring.
Verify drive parameter are set correctly.
Check BACnet master configuration
programming to verify proper addressing.
MCU
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 parameter are set correctly.
Check EIP master configuration
programming to verify proper addressing.
MCU
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.
MCU
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.

Drive Under Temp Warning/Fault
•
Cold weather mode is not
enabled, and unit temperature is
less than -10 degree.
•
Cold weather mode is enabled
and Under Temp Fault Override is
not set, unit temperature is less
than -30 degree.
•
Cold weather mode is enabled
and
under Temp Fault Override is not
set, unit temperature is -20~ -30
degree. The temp <-20 degree
when cold weather start time out.
If unit temp -20 ~ -10 degree, start motor
in cold weather mode. If unit temp <-20
degree, Warm up unit above -20deg C
for proper operation using cold weather
mode. If still < -20 degree when cold
weather mode time out, try higher output
voltage in cold weather mode.

91
Option Card Fault Configurable Fault External supply on the
DeviceNet communication
connector is not present.
Check voltage and wiring of power supply
of the DeviceNet communication.
MCU
92
External Fault 2 Configurable Fault Digital input is activated for
external
fault input.
Check digital input settings and
verify input level, could be an
external device causing fault.
MCU
93
External Fault 3 Configurable Fault Digital input is activated for
external
fault input.
Check digital input settings and
verify input level, could be an
external device causing fault.
MCU

Drive OverTemp
Warning
Warning Drive is 10 degrees from the trip
point of 90 deg C.
Check the drive degree DSP
104
Compatibility Fault Warning DSP firmware is not compatible
with MCB firmware
Check the DSP firmware revision MCU
