Chapter 3 Fault Messages
82 Primary DSP Not Compatible with PLC The firmware version of the DSP is not compatible with the software
version of the PLC.
1. Read the firmware version of the DSP and software
version of the PLC from the “Version Information”
page on the HMI.
2. Check the major numbers of the above versions. If the
software version is wrong, flash the device with the
correct software version. If the firmware version is
wrong, replace the board with a correct one.
83 Versions of System Not Compatible This fault occurs if one or more of the incompatible version faults has
occurred.
• Verify the other incompatible version faults. If no such
faults exist, contact the service engineer.
84 DIP Configuration Fault in PWMA The DIP configuration in PWMA board is not the same as P7. • Check P7 and DIP configuration in the PWMA board in
the control box.
85 Bypass Cell Reactivation Fault The bypass command was sent but the DSP did not receive the
feedback signal within the time set in Power Cell Reactivation Time
Upper Limit (P078).
• Check parameter Power Cell Reactivation Time Upper
Limit (P078) is set correctly.
• Check hardware of the power cell.
• Check configuration of the power cell.
• Check the fiber optic cable.
86 PCCB Parameters R/W Timeout After medium voltage energized, the read or write of PCCB parameters
was not completed within the time defined in the code.
• Check the fiber optic cable in the control box and PCCB
board.
• Check the hardware of the PCCB board.
87 Power Cells Parameters Mismatch For each power cell there are 21 parameters.
This fault occurs if the value of parameters 1...14,19, or 20 is not the
same in all the power cell.
• Check the fiber optic cable in the control box and PCCB
board.
• Check the hardware of the PCCB board.
• Check the power cell parameter settings interface to
locate the mismatched parameters.
88 DC Bus Voltage Deviation Fault The deviation between the DC bus voltage in one PCCB and the average
value of DC bus voltage in this phase is more than the value of DC Bus
Voltage Deviation Fault Threshold (P266) for the duration set in DC Bus
Voltage Deviation Fault Filter Time(P267).
• Check the fiber optic cable in the control box and PCCB
board.
• Check parameter DC Bus Voltage Deviation Fault
Threshold (P266) is set correctly.
• Check the hardware of the PCCB board.
89 DIP Configuration Fault in PWMB The DIP configuration in PWMB board is not the same as P7. • Check P7 and DIP configuration in the PWMB board in
the control box.
90 DIP Configuration Fault in PWMC The DIP configuration in PWMC board is not the same as P7. • Check P7 and DIP configuration in the PWMC board in
the control box.
91 Transformer Cabinet Fan Configuration
Error
The total amount of transformer cabinet fans (Fan Control Group #1 Fan
Number (P095) + Fan Control Group #2 Fan Number (P096)) has
exceeded the maximum amount set in Fan Control Transformer Cabinet
Fan Quantity Upper Limit (P106).
• Check the parameters are set correctly. The sum of
Fan
Control Group #1 Fan Number (P095) and Fan Control
Group #2 Fan Number (P096) should not be more than
Fan Control Transformer Cabinet Fan Quantity Upper
Limit (P106).
92 Input Circuit Breaker Tripped If one or more faults have occurred and the input circuit breaker is
open, this message is sent to the HMI.
This is not an actual fault.
–
93 Transformer Over Temperature Trip The TX temperature is monitored by a detector on the TX cabinet door.
If the temperature has exceeded the setting, a fault signal will be sent.
• Verify the TX temperature.
• Verify temperature monitor is over temperature
threshold setting for the TX cabinet.
• Check hardware of the temperature monitor in the TX
cabinet.
• Check input voltage or current harmonic distortion.
94 Power Cell Cabinet Fan Fault The motor protector trips while the drive is running, which is caused by
a power cell cabinet fan fault.
Fault includes short circuit, over temperature, phase loss, and so on.
• For AC fan, check fan status to determine which fan in
the power cell cabinet has faulted.
• For EC fan, check the status of the faulted fan and the
related relay (PLC2 I-06).
95 Transformer Cabinet Fan Fault The motor protector trips while the drive is running, which is caused by
a transformer cabinet fan fault.
Fault includes short circuit, over temperature, phase loss, and so on.
• For AC fan, check fan status to determine which fan in
the transformer cabinet has faulted.
• For EC fan, check the status of the faulted fan and the
related relay (PLC2 I-05).
96 Auxiliary Power Off The auxiliary power is off. Check CB1 and CB3.
97 Cabinet Door Open The cabinet door is open. Check the cabinet door and limit switch.
