4 Trial Operation4-104.4 Trial Operation with the Servomotor Connected to the MachinePerform the following steps for trial operation when the servomotor is connected to the machine.The steps are specified on the condition that trial operation for servomotor without load has been completed ineach control method.WARNING• Malfunctions that occur after the servomotor is connected to the machine may not only damage themachine, but may also cause an accident resulting in death or injury.Always make sure that the overtravel signals (P-OT and N-OT) are enabled for trial oper-ation with the servomotor connected to the machine to provide a protective function.Step Operation Reference1Turn ON the control power and main circuit power supplies and make the settings formechanical configuration related to protective function such as safety function, over-travel, and brake.When using the safety function, connect a safety function device to CN8.Note:• When not using the safety function, use the SERVOPACK with the safety functionjumper connector (provided as an accessory) inserted into CN8. If the SERVO-PACK is used without the jumper connector inserted into CN8, no current willflow to the servomotor and no torque will be output. In this case, "Hbb" will be dis-played on the panel operator or the digital operator.• When a servomotor with brake is used, take advance measures to prevent vibrationdue to gravity acting on the machine or external forces before checking the brakeoperation. Check that both servomotor and brake operations are correct.5.11 Safety Function3.3.2 Safety Function Sig-nal (CN8) Names andFunctions5.2.3 Overtravel5.2.4 Holding Brakes2Set the necessary parameters for control method used. 5.3 Speed Control5.4 Position Control5.5 Torque Control3Connect the servomotor to the machine with coupling, etc., while the power is turnedOFF.−4Turn ON the power to the machine (host controller) and then check that the SERVO-PACK and converter are servo OFF status. Check again that the protective function instep 1 operates normally.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-renceCN1To host controllerTo main circuitpower supplyTo controlpower supplySecure the motor flange tothe machine and connectthe motor shaft to the loadshaft with a coupling orsimilar mechanism.
