East yuan TSTA server maintenance
Model: TATA-TSB302B2
Failure phenomenon: ER-03 overload alarm
Failure analysis: the customer response to the server in less than 2 minutes on the alarm overload. According to the instructions, the solution to the problem is solved as follows.
1, check the motor terminal connection (U, V, W) and encoder wiring is normal.
2, check whether the drive parameters are consistent with the applicable motor (reference Dn015).
3, adjust the drive gain, improper adjustment will result in motor resonance.
4, within the scope of the license will be extended to extend the time, or to reduce the inertia of the load.
* this message usually occurs in the action, if the action does not take long to abnormal, please make 1, 2 inspection often.
* 03707 edition over load time increased to 2 times. (to observe the changes in Dn019)
According to the above check occurs after all normal. Exclude peripheral problems. Focus on the power supply and the driver board, the power to check the driving voltage is normal. In check the IGBT module is also normal. Found in the movement to drive the U phase voltage was lower than other places around 1.2V in motor measurement, power driver and replacement regulator after power on normal operating voltage test. Client installed to test everything is normal.
East yuan server common faults: no show, lack of phase, over current, over voltage, under voltage, over heat, over load, ground, parameter errors, there is no output can not be repaired.
