Fault and Warning Codes

9000X AF Drives MN04001004E—May 2011 www.eaton.com 83

Fault Codes, continued

Fault Code Fault Possible Cause Solution

29** Thermistor fault The thermistor input of an option board has detected

a high motor temperature

Check the motor cooling and the motor loading

Check the thermistor connection

(If the thermistor input of an option board is not being

used, it must be short-circuited)

31 IGBT temperature (hardware) IGBT inverter bridge overtemperature protection has

detected a high short-term overload current

Check loading

Check motor size

32 Fan cooling The SVX9000/SPX9000 cooling fan did not start when

commanded

Contact your Eaton distributor

34 CAN bus communication Sent message not acknowledged Ensure that there is another device on the bus with

the appropriate configuration

36 Control unit The control unit cannot control the power unit and

vice-versa

Change the control unit

37* Device change

(same type)

Option board changed

Different power rating of drive

Reset

No Fault Time Data Record is made

38* Device added

(same type)

Option board added

Drive of different power rating added

Reset

No Fault Time Data Record is made

39* Device removed Option board removed

Drive removed

Reset

No Fault Time Data Record is made

40 Device unknown Unknown option board or drive Contact your Eaton distributor

41 IGBT temperature IGBT inverter bridge overtemperature protection has

detected a high short-term overload current

Check loading

Check motor size

42** Brake resistor

overtemperature

Brake resistor overtemperature protection has

detected excessive braking

Set the deceleration time longer

Use an external brake resistor

43 Encoder fault Exceptional fault data record, see the Active Fault

Menu and Fault Time Data Record for more

information. Additional codes:

1 = Encoder 1 channel A is missing

2 = Encoder 1 channel B is missing

3 = Both encoder 1 channels are missing

4 = Encoder reversed

Check encoder channel connections

Check the encoder board

44* Device change

(different type)

Option board changed

Different power rating of drive

Reset

No Fault Time Data Record is made

Application parameter values restored to default

45* Device added

(different type)

Option board added

Drive of different power rating added

Reset

No Fault Time Data Record is made

Application parameter values restored to default

50** Analog input I

<4 mA

(for the signal range

4 to 20 mA)

Current at the analog input is <4 mA

Control cable is broken or loose

Signal source has failed

Check the current loop, signal source, and wiring

51 External fault Digital input set as an external fault input has been

triggered

Check source of trigger

52 Keypad communication fault The connection between the control keypad and the

SVX9000/SPX9000 has been lost

Check the keypad connection and keypad cable

53 Communication bus fault The data connection between the communication bus

master and the communication bus board has failed

Check installation

If installation is correct contact your Eaton distributor

54 Slot fault Defective option board or slot Check that the board is properly installed and seated

in slot. If the installation is correct, contact your Eaton

distributor

56 PT100 board temperature

fault

Temperature limit values set for the PT100 board

parameters have been exceeded

Determine the cause of the high temperature
