Drive Fault Displays and Explanations (cont'd)

DBR OVERCURRENT

Cause: IGBT7 (dynamic braking transistor) is damaged

Comments: Check ohm value connected to "PA" and "PB" terminals (see page 9-16 for minimum ohm values). If using multiple resistors, make sure parallel-series combination is wired correctly. Check IGBT7. Check DC bus fuse for continuity; if open, check output transistors. Consult your Toshiba distributor for authorized service.

DBR OVERLOAD

Cause: Dy namic braking resistor is in danger of overheating (as determined by drive).

Comments: Check that the values entered into Item 143, BRAKING RESISTOR VALUE and Item 144, BRAKING RESISTOR POWER RATING are correct.

OVERHEAT

Cause: Drive's heatsink exceeded 90o C.

Comments: Check drive's muffin fans (if any). Clear heatsinks of anything blocking airflow.

The enclosure that the drive is installed in may be too small or there may be to many heat sources in the same enclosure. Drive may not have been properly sized for operating altitude. Thermistor on heatsink may be bad.

EMERGENCY OFF

Cause: Drive received one of the following ESTOP commands:

1.Drive was receiving STOP/START command via terminal strip when STOP button on keypad was pressed.

2.One of the drive's input terminal's function is set to "10" (see Items 44-55 and page 9-9), and terminal is being opened/closed to command ESTOP.

EEPROM WRITE FAILURE or EEPROM READ FAILURE Cause: EEPROM was unable to read/write to peripherals.

Comments: Check for miswiring that may be causing noise (such as "CC" connected to ground, an external 10 volt source connected to "PP" etc.) Control board may need to be replaced (part number 45996). See picture of board on page 5-2.

RAM ERROR or ROM ERROR

Comments: Check for miswiring that may be causing noise (such as "CC" connected to ground, an external 10 volt source connected to "PP" etc.). Replace control board (part number 45996). See picture of board on page 5-2.

OPTION ROM ERROR

Comments: Check for miswiring that may be causing noise (such as "CC" connected to ground, an external 10 volt source connected to "PP" etc.). If drive is energized with option ROM installed and is later energized without option ROM installed, this fault will appear. Reset in normal fashion.

CPU ERROR

Comments: If option ROM or option board is installed or removed when drive is powered, this fault will appear. Reset like any fault. Check for miswiring that may be causing noise (such as "CC" connected to ground, an external 10 volt source connected to "PP" etc.). If the CPU is truly damaged, the fault will not reset and replacement of the control board (part number 45996) is necessary. See picture of control board on page 5-2.

COMMUNICATION ERROR

Cause: RS232 or RS485 timer did not respond

Comments: Check wiring to RS232 or RS485 ports. Check setting of Item 264, COMMUNICATION SELECTION (should be "1" for RS485). Check jumpers J1, J2, and J3 on RS485 option board (see RS485 Communications Option Manual). Cable may be broken.
