4.5 Trial Operation of Servomotor with Brakes4-114 Trial Operation4.5 Trial Operation of Servomotor with BrakesObserve the following precautions when performing a trial operation of servomotor with brake.• When checking the brake operation, take advance measures to prevent vibration due to gravity acting on themachine or external forces.• Check the servomotor operation and holding brake operation with the servomotor separated from themachine. If both operations are correct, connect the servomotor and perform trial operation.Holding brake operation of the servomotor with brake can be controlled the brake interlock output (/BK) sig-nal of the SERVOPACK.For wiring on a servomotor with brakes, and setting parameters, refer to 5.2.4 Holding Brakes4Turn ON the power to the machine (host controller) and then check that the SERVO-PACK is servo OFF status. Check again that the protective function in step 1 operatesnormally.Note: For steps 4 to 8, take advance measures for emergency stop so that the servo-motor can stop safely when an error occurs during operation.5.2.5 Stopping Servomo-tors after /S_ON TurnedOFF or Alarm Occur-rence5Perform trial operation with the servomotor connected to the machine, followingeach section in 4.3 Trial Operation for Servomotor without Load from Host Refer-ence.Check that the trial operation is completed with as the trial operation for servomotorwithout load. Also check the settings for machine such as reference unit.4.3 Trial Operation forServomotor without Loadfrom Host Reference6 Check the settings of parameters for control used set in step 2 again.Check that the servomotor rotates matching the machine operating specifications.7Adjust the servo gain and improve the servomotor response characteristics, if neces-sary.6 Adjustments8Write the parameters set for maintenance in 11.4 Parameter Recording Table.Then the trial operation with the servomotor connected to the machine is completed.Note: If the JUSP-OP05A digital operator is used, parameters can be saved. Sig-maWin+, which is a tool for supporting the servo drive, can then manage thesaved parameters in files.11.4 Parameter Record-ing TableStep Operation ReferenceNote: The servomotor will not be broken in completely during the trial operation.Therefore, let the system run for a sufficient amount of additional time toensure that it is properly broken in.
