ABBACS550 drive F04 alarm service

ABB ACS550 drive repair ABBacs550 alarm F04 is ABB high performance vector control inverter, compact design, wide power range. User Manual in small power and high-power: ACS550-01 / U1 User's Manual power range (0.75 ... 160 kW). ACS550-02 / U2 User's Manual power range (200 ... 355 kW). Customer contact a ABBacs550-01-246a (132kw) inverter, normal use before the National Day, the boot fault message F04 discharged after false. F04 This output short circuit failures are generally meant to guide plant electricians disconnect uvw motor output line, no-load start the fault persists, determined drive bad. ACS550 output short circuit integrates a number of detection, the module short circuit, output driver board imbalance, the drive pulse processing board failure, have reported F04. After a detailed inspection, found no problem of power IGBT module, the drive pulse detection, discovery-driven deterioration board a 270 ohm resistor. After the substitution, boot normally, the load test of the indicators correctly, the drive normal repair. Analyze the causes deterioration chip resistors are generally a gradual process, because this equipment has been used, no problem is found, in fact, the fault has been there, but down over time, the drive to cool back to room temperature after the state, the resistance completely degenerate When starting the inverter board to detect the timing uvw alternately turn angle, when a unit can not provide this parameter, the program defaults to output short circuit, start the alarm.
