Confirming Safety Functions

When starting the equipment or replacing the SERVOPACK or converter for maintenance, be sure to conduct
the 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 that
the 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 be
considered. 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.

Connecting a Safety Function Device

Connect a safety function device using the following procedure.
1.
Remove the safety function's jumper connector from CN8.
2.
Connect a safety function device to CN8.
Note: When not using the safety function, use the SERVOPACK with the safety function's jumper connector (JZSP-
CVH05-E provided as an accessory) inserted in CN8. If the SERVOPACK is used without the jumper connector
inserted into CN8, no current will flow to the servomotor and no torque will be output. In this case, "Hbb" will be
displayed on the digital operator.
