APPLICATIONS OF Σ-SERIES PRODUCTS3.4.2 Using Dynamic Brake1083) For detailed adjustment procedures, refer to the following sections.Adjustment Method1) Automatic adjustment ofreference offset 4.2.4 Reference Offset Automatic Adjustment2) Manual adjustment of referenceoffset4.2.5 Speed Reference Offset ManualAdjustmentMode3.4.2 Using Dynamic Brake1) To stop the servomotor by applying dynamic brake (DB), set desired values in the fol-lowing memory switch. If dynamic brake is not used, the servomotor will stop naturallydue to machine friction.Cn-01Bit 6 How to Stop Motor WhenServo is Turned OFFFactorySetting: 0For Speed/Torque Controland Position ControlCn-01Bit 7Operation to Be PerformedWhen Motor Stops AfterServo is Turned OFFFactorySetting: 1For Speed/Torque Controland Position ControlThe Servopack enters servo OFF status when:• Servo ON input signal (S-ON, 1CN-40) is turnedOFF• Servo alarm arises• Main power is turned OFFSpecify how to stop the motor when one of theabove events occurs during operation.Setting Meaning0 Stops the motor by dynamic brake.Cn-01 bit 6 1 Causes the motor to coast to a stop.The motor power is OFF and stops due to machine friction.If dynamic brake stop mode is selected, specify the operation to be performed whenthe motor stops.Setting MeaningCn 01 bit 7 0 Releases dynamic brake after the motor stops.Cn-01 bit 7 1 Does not release dynamic brake even after the motor stop.TERMS Dynamic brake (DB)One of the general methods to cause a motor sudden stop.“Dynamic brake” suddenly stops a servomotor by shorting itselectrical circuit.This dynamic brake circuit is incorporated in the Servopack.Servopack Servomotor3Servo OFFStop modeStop bydynamicbrakeAfter stopReleasingdynamic brakeBit 7Holdingdynamic brakeBit 6Coastingto a stop Remains beingreleaseddynamic brake
