Do you know the routine maintenance of the servomotor?

(1) Servo motor normal operation, should be done every day to do the routine inspection of the inverter, the main contents of the tour include: the drive running instructions to the remote and the local is accurate, the operation mode and requirements are in line with the inverter operating parameters Stop, whether or not to report the inverter fan operation is normal inverter cabinet reactor overheating or electromagnetic noise inside the inverter whether there is vibration or abnormal sound. Such as the discovery of any of the above-mentioned circumstances, in conditions permitting, should be dealt with in a timely manner.

(2) Servo motor As the output is used as a contactor, should be out of the equipment, often on the output cabinet main contactor and other auxiliary contacts to check, carefully observe the contactor static and dynamic contact with or without the arc, burr or surface Oxidation, rugged, found that such problems should be replaced by the corresponding dynamic and static contact to ensure that its contact safe and reliable, and will not appear phase imbalance.

(3) Servo motor regularly check the inverter, cleaning, dust, focusing on rectification, inverter parts and control cabinet, remove the inverter under the air inlet, the dust on the outlet.

(4) Servo motor In the overhaul (usually 4 years), should be checked as follows: input 'rectifier and inverter, DC input fast melt to conduct a comprehensive inspection and found that the timely replacement of the capacitor one by one to check whether the local overheating of the capacitor, the appearance of No bubble or deformation, if there should be replaced on the rectifier, inverter part of the diode, G Ding O with a multimeter for electrical testing, determination of its forward and reverse resistance, to see if the resistance between the pole is normal, the same model Device consistency is good, if necessary, to replace the two carefully check the control circuit of the terminal row with no aging, loose, the connection is tight, the circuit board is installed to check the inverter within the AC and DC bus (including Inverter line or output line) with or without deformation, corrosion, oxidation, busbar connection screws whether the loose, the installation of fixed points at the fastening screws whether the loose, fixed with insulation or insulation column whether the aging Cracking or deformation, if there should be timely replacement, re-fastening, does not allow the busbar or connecting bolts appear ground or ground discharge may be on the output thermal relay contactor school Check, check the value and contact is correct and reliable.
