28
Device Removed
Fault
Optional board removed from slot, or power
board removed from control board
Device no longer available
29
Device Unknown
Fault
Unknown device connected (power
board/option board
Device no longer available
30
IGBT OverTemp
Fault
IGBT temperature is too high
• Check loading
• Check motor size
• Decrease switching frequency
31
Encoder Fault
Fault
• Encoder 1 channel A is missing
• Encoder 1 channel B is missing
• Both encoder 1 channels are missing
• Encoder reversed
• Encoder board missing
• Check encoder connections
• Check encoder and encoder cable
• Check encoder board
• Check encoder frequency in open loop
32
AIN<4 mA
(4 to 20 mA
Configurable
1
No Action
33
External Fault
Configurable
1
Fault
Digital input
34
Keypad
Communication Fault
Fault
The connection between the control
keypad and frequency converter is broken
Check keypad connection and possible
keypad cable
35
FieldBus
communication Fault
Configurable
1
Fault
Except communication board, also control
board can communicate with external device
using RS-485 port, so the possible cause
includes the connection between external
device and control board
Check installation and Fieldbus master
36
OPT Card Fault
Configurable
1
Fault
Defective option card or slot
Check option card and slot
37
BypassOverLoad
Fault
Over load when motor is in bypass mode
Check motor connection situation
38
Real time clock fault Configurable
1
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
39
PT100 Fault
Configurable
1
Fault
Temperature is over user set value
Pt100 short, open or over temperature
40
Motor ID fault
Fault
The Motor ID Run was not completed
successfully
Check motor size
Motor may be not compactable with VFD
41
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
42
Possible power
wiring error detected
Fault
Reserved
43
Control Board
OverTemp
Fault
Control board is over +85 degrees or under
–30 degrees
Check NTC resistor
Check control board temperature
44
Internal-ctrl Supply
Fault
+24V port voltage is over 27V or under 17V
Check voltage range of +24V
45
Too Many Speed
Search Restarts
Fault
Speed searching failed
Check motor parameters’ setting
46
Current Unbalance
Fault
Reserved
47
Replace Battery
Configurable
1
Warning
Battery voltage is too low
Check the battery
48
Replace Fan
Configurable
1
Warning
Fan life is less than 2 months
Check the fan
49
Safe Torque Off
Fault
STO Triggered
Reset STO Trigger
50
Over Current
Controller
Warning
The output current has reached the current
limit value
Check the load
Set the acceleration time longer
51
Over Voltage
Controller
Warning
The DC link voltage has reached its voltage
limit value
Check the input voltage
Set the acceleration/deceleration time
longer
