6-4 Inverter Faults

HDetecting Inverter Faults

When a fault is detected in the Inverter itself, the status will change as shown in the following table.

Function

Inverter Fault Status

 

 

Remote I/O

The fault output allocated in the remote I/O will turn ON.

 

If the fault output is ON, turn OFF all related inputs controlling the Inverter,

 

and program a sequence to stop the program.

 

 

Explicit messages

Read the fault output for Class 29, Instance 1, Attribute 0A using message

 

communications. If there is a fault in the Inverter, the fault output will be ON,

 

so turn OFF all related inputs controlling the Inverter, and program a

 

sequence to stop the program.

 

 

Special remote I/O

Read register 0010, and check whether bit 07 (fault output) is ON (serious

 

fault). If bit 07 is ON, turn OFF all related inputs controlling the Inverter, and

 

program a sequence to stop the program.

HConfirming Inverter Fault Status

The fault information for the Inverter can be checked by using the following methods. Perform trouble- shooting based on the information corresponding to the fault and refer to maintenance information in the SYSDRIVE 3G3FV High-functionGeneral-purpose Inverter User’s Manual (I516).

Function

Inverter Error Status

 

 

Operation indicators on

When there is an Inverter fault, the details will be displayed on the Digital

Inverter

Operator of the Inverter. The fault log can be checked using the monitor

 

function (U3).

 

 

Explicit messages

Read the fault code for Class 29, Instance 1, Attribute 0D using message

 

communications. The code corresponding to the Inverter fault is specified.

 

 

Special remote I/O

Read registers 0014 to 0018. Check the fault status from the bit signals that

 

are output for an Inverter fault. The fault log can be checked using the

 

monitor function (U3) in registers 0090 to 0093.

HMemory Data Backup

The SYSDRIVE 3G3FV Inverter uses EEPROM for the data backup. Data is written to EEPROM when the parameters change or the power is turned OFF.

•Data can be written to EEPROM up to 100,000 times.

•Parameters are always written to EEPROM when they are changed using CompoBus/D communica- tions, so limit the times that parameters are written to EEPROM as much as possible.

(With the special I/O, data will be written to EEPROM when an enter command is received.)

•Frequency reference and control command (register numbers 0000 to 000F for the special I/O) and the Net Control Bit and Net Reference Bit are not written to RAM or EEPROM. When the power is turned OFF, any specified values are cleared.
