8.3 Setting Common Basic Functions8.3.5 Selecting the Stopping Method After Servo OFFThe stopping method when the power to the SERVOPACK turns OFF can be selected.Pn001Parameter Stop Mode Mode AfterStoppingn.0Dynamic BrakeMeaningStops the servomotor by dynamic braking (DB),then holds it in Dynamic Brake Mode. (Factory setting)n.1Stop by dynamicbrakeCoast Stops the servomotor by dynamic braking (DB),then places it into Coast (power OFF) Mode.n.2 Coast to a stop Coast Stops the servomotor by coasting, then places itinto Coast (power OFF) Mode.These parameters are valid under the following conditions:• When the /S-ON input signal is OFF (Servo OFF).• When an alarm occurs.• When main circuit power supply (L1, L2, L3) is OFF.Similar to the Coast Mode, the n.0 setting (which stops the servomotor by dynamic braking and then holds it inDynamic Brake Mode) does not generate any braking force when the servomotor stops or when it rotates at very low speed.• TERMS• Stop by dynamic brake: Stops by using the dynamic brake (with short-circuiting by a circuit of SERVOPACK).• Coast to a stop: Stops naturally, with no brake, by using the friction resistance of the motor in operation.• IMPORTANTThe SERVOPACK is forced to stop by dynamic braking, regardless of the settings of this parameter, when the main circuitpower supply (L1, L2, L3) or control power supply (L1C, L2C) turns OFF.• SGDH-A3BE to -02BE (30 to 200 W for 100 V)• SGDH-A3AE to -15AE (30 to 1.5 kW for 200 V)• SGDH-05DE to -75DE (0.5 kw to 7.5 kW for 400 V)If the servomotor must be stopped by coasting rather than by dynamic braking when the main circuit power supply (L1, L2,L3) or the control power supply (L1C, L2C) turns OFF, arrange the sequence externally so the servomotor wiring (U, V, W)will be interrupted.IMPORTANTThe dynamic brake (DB) 1 is an emergency stop function.If the servomotor is frequently started and stopped by turning the power ON/OFF or using the servo ON signal(/S-ON), the DB circuit will also be repeatedly operated, degrading the SERVOPACK’s internal elements.Use the speed input reference and position reference to control the starting and stopping of theservomotor.8TERMS1 Dynamic brake (DB)A common method for quickly stopping a servomotor. The servomotor is stoppedby short-circuiting the servomotor circuit. This circuit is built into the SERVO-PACK.SERVOPACKServomotor8-25
