Appendix C Basic Inspection and Maintenance ASDA-B2-FC-2 September, 2015CBasic InspectionItem ContentGeneral inspectionPeriodically check if the screws of the servo drive, the connection between the motorshaft and the mechanical system as well as the connection of terminal block andmechanical system are securely tightened.The gap of the control chamber and the installation of the cooling fan should be freefrom oil, water or metallic particles. Also, the servo drive shall be free from the cuttingpower of the power drill.If the control chamber is installed in the site which contains harmful gas or full ofdust, please ensure the servo drive is free from the harmful gas and dust.When making detector (encoder) cable or wire rods, please ensure the wiring iscorrect. Otherwise, the motor may have sudden unintended acceleration or beburned down.Inspection beforeoperation(Not connected topower yet)To avoid electric shock, the ground terminal of the servo drive should be firmlyconnected to the ground terminal of the control chamber. If the wiring is needed, waitat least 10 minutes after the drive is disconnected from the mains, or discharge theelectricity by discharge device.The splicing parts of the wiring terminal should be isolated.Make sure the wiring is correct so as to avoid damage or any irregularity.Check if the electrically conductive objects such as screws, sheet metal orinflammable objects are not inside the servo drive.Check if the control switch is in OFF status.Do not place the servo drive or external regenerative resistor onto inflammableobjects.To avoid the electromagnetic brake losing efficacy, please check if the stop functionand circuit break function can work normally.If the peripheral devices are interfered by the electronic instruments, please reduceelectromagnetic interference with devices.Please make sure the external voltage level of the servo drive is correct.Inspection beforerunning the servodrive(Alreadyconnected topower)The detector (encoder) cable should avoid excessive stress. When the motor isrunning, please ensure the cable is not frayed by the machine or over extended.Please contact Delta if there is any vibration of the servo motor or unusual noiseduring operation.Make sure the setting of the parameters is correct. Different machinery has differentcharacteristic, please adjust the parameter according to the characteristic of eachmachinery.Please reset the parameter when the servo drive is in the status of SERVO OFF, or itmay cause malfunction.Please contact Delta if there is no contact sound or other irregular sound occurswhen the relay is operating.Check if the power indicator and LED display works normally.
