EA180 Series Servo Drive Users Manual Maintenance and Inspection Please carry out regular maintenance and inspection on the drive and motor for safe use. 1) The operator should first cut off the power supply. Do not approach the motor and the machine it drives when wrong actions occur during power-on. 2) For a short period of time after the power supply is cut off, the internal circuit still maintains a high voltage charging state. Before inspection, the power supply must be cut off; wait for 10 minutes, and make sure that the charging light is completely off. 3) If it is necessary to test the insulation resistance of the drive, all connections to the drive must be cut off.
Insulation resistance test on the drive connected with wires or a motor will damage the device. 4) Do not use gasoline, diluents, acidic or alkaline detergents to clean the device, otherwise discoloration or damage to the case may occur. Normal use conditions The environmental conditions are as follows: the annual average temperature is 30 ℃ , the average load rate is below 80%, and the daily operation time is below 20 hours.
