Jia Hong Wei maintenance of the servo drive series: MSD, A4, A5 series. Can repair the common faults of the servo driver: no show, lack of phase, over current, over voltage, under voltage, over current, over load, over load, ground, parameter error, display no output, module damage, etc.
Description
MBDH servo drive repair
Model: MBDHT2510
Failure phenomenon: ERR12 alarm
Fault analysis: according to the fault code query for the server over voltage alarm, customer response is in the power to make it after the report to the fault code, reported over voltage causes the power supply voltage is higher than the allowable input voltage range. The voltage between P and N on the inverter exceeds the specified value. Power supply voltage is too high. Presence of capacitive loads makes the line voltage rise.
1) missed regenerative discharge resistance.
2) external regeneration discharge resistance does not match, can not absorb renewable energy.
(3) driver (internal circuit) defective.
Static measuring voltage detecting circuit element is normal. Power measurement via AD7401 operating voltage is normal. DC bus voltage and voltage detection point power supply voltage is normal. Initially identified as the voltage detection process after processing or motherboard CPU fault. In the exclusion of the main board and the brake unit outside the focus of the test drive internal voltage detection circuit. The analysis of the measurement found that the power supply IC B1175 no voltage output. After replacement voltage is normal. To re connect the motor after all normal.
