Fault
code Fault Name Fault Type Default Possible Cause Remedy Realization
52
Keypad Comm Fault Configurable Fault The connection between the
control “keypad and frequency
converter is broken, and The local
reference is keypad reference or the
local control place is keypad, and
The keypad communication fault
protection is not “NO action”
Check keypad connection and possible
keypad cable.
MCU
54
Option Card Fault Configurable Fault Defective option card or option
card slot
•
Check right option card and option card
slot connections.
•
Check Board Status on Keypad for
exact cause of fault.
•
Contact distributor nearest you.
MCU
55
Real-time Clock Fault Configurable Warning
•
Communication between MCU
and RTC chip isn’t normal
•
The power of RTC chip
isn’t normal
•
The real time isn’t normal
Check the RTC chip, power cycle to drive.
If issue continues contact distributor
near you.
MCU
56
PT100 Fault Configurable Fault Temperature is beyond the limit of
sensing capacity of PT100
Pt100 short, open or over temperature,
check PT100 temperature probe.
MCU
57
Motor ID fault Fault The Motor parameters Identification
running was not completed
successfully
•
Check motor size
•
Verify the input and output wiring is
connected properly.
DSP
58
Current Measure Fault Fault Current measurement is out of
range
Restart the drive again. Should the fault
re-occur, contact the distributor near to
you
DSP
59
Power Wiring Error Fault Power wiring connected to output
of drive.
Verify power input wiring is connected
to L1, L2 and L3 terminals and they are
properly torqued.
DSP
60
Control Board
Over Temp
Fault Control board is over +85 degrees
or under –30degrees
•
Check NTC resistor
•
Check control board temperature
MCU
61
Internal Control Supply Fault +24V port voltage is over 27V or
under 17V
Check voltage range of +24V on terminals
12 to 13. If voltage is out of range contact
distributor near you.
MCU
62
Speed Search Fault Fault Speed searching failed when
performing flying start.
Check motor parameters’ setting and
motor connections.
DSP
64
Replace Battery Configurable Warning RTC Battery voltage is too low. Check the RTC battery voltage, contact
distributor near you for replacement
battery.
MCU
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.
MCU
66
Safety Torque Off Fault STO Triggered, STO input is open. Reset STO Trigger and verify wiring.
Reset fault after input is enabled.
DSP
67
Current Limit Control Warning The output current has reached the
current limit value
•
Check the load
•
Set the acceleration time longer
DSP
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
DSP
69
System Fault Fault Thermistor spi communication error. Check thermistor chip. MCU
70
System Fault Fault MCU send wrong parameters
to DSP.
Restart the drive again. Should the fault
re-occur, contact the distributor near to
you.
DSP
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 RS485 communication wiring.
Verify drive parameter are set correctly.
Check master programming to verify
proper addressing.
