BASIC USES OF Σ-SERIES PRODUCTS2.4.4 Supplementary Information on Test Run462.4.4 Supplementary Information on Test RunIn the following cases, always refer to the information described below before starting a testrun:• When using a servomotor with a brake• When performing position control from the host controller1) When using a servomotor with brakeThe brake prevents the motor shaft from rotating due to a backdriving torque. Such atorque may be created by an external force or the force of gravity acting on the load andmay result in undesired motion or the load, should motor power be lost.Servopack uses the brake interlock output (BK) signal to control holding brake operationfor a servomotor with brake.• Vertical axis • Axis to which external force is appliedServomotorHolding brakePrevents themotor fromrotating due togravityExternal force ServomotorNOTE To prevent faulty operation caused by gravity (or external force), first check that the motorand holding brake operate normally with the motor disconnected from the machine.Then, connect the motor to the machine and conduct a test run.For wiring of a servomotor with a brake, refer to 3.4.4 Using Holding Brake.Brake control relayBrake power supplyLPSE-2H01 (200 V input)LPDE-1H01 (100 V input)Power supply:single-phase200 V or 100 V Servopack Cable for motor withbrake9.8ft DP9320083-116.4ft DP9320083-232.8ft DP9320083-349.2ft DP9320083-465.6ft DP9320083-5Servomotor with brake2
