5.2 HWBB Function5.2.8 Operation without a Host Controller5-105.2.8 Operation without a Host ControllerThe HWBB function will operate even for operation without a host controller.However, if the HWBB function operates during execution of the following functions, leave theexecution mode for the function and then enter it again to restart operation. Do this for bothaxis A and axis B. Operation will not be restarted simply by turning OFF the /HWBB1 and /HWBB2 signals.5.2.9 /S-RDY (Servo Ready Output) SignalThe SV_ON (Servo ON: 31 hex) command will not be acknowledged in the HWBB state. There-fore, the Servo Ready Output Signal will turn OFF.The Servo Ready Output Signal will turn ON if both the /HWBB1 and /HWBB2 signals are ONand the servo is turned OFF (BB state).An example is provided below for when the main circuit power supply is ON and the SENS_ON(Turn Sensor ON) command is input when there is no servo alarm. (An absolute encoder isused in this example.) The same operation is performed for axis A and axis B.ApplicableFunctions Resetting the HWBB State• Jogging• Origin search• Program jogging• Automatic adjust-ment without hostreference• EasyFFT• Adjustment ofmotor currentdetection signaloffset/HWBB1/HWBB2SERVOPACKstatus for axis AFunction executionmode for axis AFunction executionmode for axis BSERVOPACKstatus for axis BOFF (motor currentshut-OFF request)ON(normal operation)ON(normal operation)Not functionexecution modeFunctionexecution modeFunctionexecution modeNot functionexecution modeFunctionexecution modeFunctionexecution modeHWBB state BB state Operating stateOperating stateHWBB state BB state Operating stateOperating stateThe following example uses the Σ-7W SERVOPACK with MECHATROLINK-III commands.
