8.1 Trial OperationStep Item Description Reference1Installationand mountingInstall the servomotor and SERVOPACK according to the installation conditions.(Do not connect the servomotor to the machine because the servomotor will be operatedfirst under a no-load condition for checking.)−2Wiring andconnectionsConnect the power supply circuit (L1 and L2 or L1, L2 and L3), servomotor wiring(U, V, W), I/O signal wiring (CN1), and encoder wiring (CN2). During (1) TrialOperation for Servomotor without Load, however, disconnect the CN1 connector.−3Turn ON thepower.Turn ON the power. Check the panel operator to make sure that the SERVOPACK isrunning normally. If using a servomotor equipped with an absolute encoder, performthe setup for the absolute encoder. (Refer to 8.4.5 Absolute Encoder Setup (Fn008).)−4Execute jogmodeoperation.Execute jog mode operation with the servomotor alone under a no-load condition.Jog Operation5Connect inputsignals.Connect the input signals (CN1) necessary for trial operation.−6Check inputsignals.Use the internal monitor function to check the input signals.Turn ON the power, and check the emergency stop, brake, overtravel, and other protectivefunctions for correct operation.−7Input the servoON signal.Input the servo ON signal, and turn ON the servomotor.HostReference8Inputreference.Input the reference for the control mode being used, and check the servomotor forcorrect operation.HostReference89Check protectiveoperation.Turn OFF the power, and then connect the servomotor to the machine.If using a servomotor with an absolute encoder, set up the absolute encoder and makethe initial settings for the host controller to match the machine’s zero position.−10Setnecessaryparameters.Using the same procedure as you did to input a reference in step 8, operate the servomotorfrom the host controller and set the parameter so that the machine’s traveldirection, travel distance, and travel speed all correspond to the reference.HostReference11 OperationThe servomotor can now be operated. Adjust the servo gain if necessary. Refer to9.1 Autotuning.If a problem occurs, refer to Chapter 10 Inspection, Maintenance, and Troubleshooting.HostReference8-5
