8.3 Setting Common Basic Functions(2) Brake Interlock OutputType Name Connector Pin SettingMeaningNumberOutput /BK Must be allocated ON (low level) Releases the brake.OFF (high level) Applies the brake.This output signal controls the brake and is used only for a servomotor with a brake. This output signal is not used with thefactory settings. The output signal must be allocated (with Pn50F). It does not need to be connected for servomotors withouta brake.• IMPORTANTThe /BK signal is not output during overtravel, or when there is no power to the servomotor.(3) Allocating Brake Signals (/BK)The brake signal (/BK) is not used with the factory settings. The output signal must be allocated.Parameter Connector Pin Number Meaning+ Terminal - TerminalPn50F n.0 − − The /BK signal is not used. (Factory setting)n.1 CN1-25 CN1-26 The /BK signal is output from output terminal CN1-25, 26.n.2 CN1-27 CN1-28 The /BK signal is output from output terminal CN1-27, 28.n.3 CN1-29 CN1-30 The /BK signal is output from output terminal CN1-29, 30.• IMPORTANTWhen set to the factory setting, the brake signal is invalid. When multiple signals are allocated to the same output terminal,the signals are output with OR logic. To output the /BK signal alone, disable the other output signals or set them tooutput terminals other than the one allocated to the /BK signal. For the allocation of SERVOPACK output signals otherthan /BK signal, refer to 7.3.3 Output Circuit Signal Allocation.(4) Setting the Brake ON Timing after the Servomotor StopsWith the factory setting, the /BK signal is output at the same time as the servo is turned OFF. The servo OFF timingcan be changed with a parameter.Pn506Delay Time from Brake Reference Until Servo OFFSpeed Position TorqueSetting Range Setting Unit Factory Setting Setting Validation0 to 5010 ms 0 Immediately(0 to 500 ms)• When using the servomotor to control a vertical axis, themachine movable part may shift slightly depending on the brakeON timing due to gravity or an external force. By using thisparameter to delay turning the servo OFF, this slight shift can beeliminated.• This parameter changes the brake ON timing while the servomotoris stopped.For details on brake operation while the servomotor is operating,refer to (5) Setting the Brake ON Timing When Servomotor Runningin this section./S-ON(CN1-40)/BK outputPower to motorServo ONBrake releasedPower to motorServo OFFBrake heldPn506• IMPORTANTThe servomotor will turn OFF immediately when an alarm occurs, regardless of the setting of this parameter.The machine movable part may shift due to gravity or external force during the time until the brake operates.No power to motor88-23
