4 Operation4.8.4 Confirming Safety Functions4-64(3) Procedure4.8.4 Confirming Safety FunctionsWhen starting the equipment or replacing the SERVOPACK or converter for maintenance, be sure to conductthe following confirmation test on the HWBB function after wiring.• When the /HWBB1 and /HWBB2 signals turn OFF, check that the digital operator displays "Hbb" and thatthe servomotor does not operate.• Check the ON/OFF states of the /HWBB1 and /HWBB2 signals with Un015.→ If the ON/OFF states of the signals do not coincide with the display, an error in the external device, dis-connection or short-circuiting of the external wiring, or a failure in the SERVOPACK or converter must beconsidered. Find the cause and correct the problem.• Check with the display of the feedback circuit input of the connected device to confirm that the EDM1 sig-nal is OFF while in normal operation.4.8.5 Connecting a Safety Function DeviceThere are two types of the safety function’s jumper connectors that are attached to SERVOPACKs. You mustremove a safety function’s jumper connector before connecting a safety function device. The connectionmethod depends on the connector type that is used. Read the following procedures well before you attach asafety function device.Use the following procedures to attach safety function devices.12346Request to open the guard.Open the guard and enter.The /HWBB1 and /HWBB2 signals areOFF and HWBB function operates.(The operation in the guard is available.)5 After completing the operation, leave andclose the guard.When the servomotor is operating, the hostcontroller stops the servomotor and sendsthe servo OFF command (SV_OFF).The host controller sends the servo ON com-mand (SV_ON).Connector Type A Connector Type B
