Validating the HWBB Function

When you commission the system or perform maintenance or SERVOPACK replacement, you
must always perform the following validation test on the HWBB function after completing the
wiring. (It is recommended that you keep the confirmation results as a record.)
• When the /HWBB1 and /HWBB2 signals turn OFF, confirm that the Digital Operator displays
Hbb and that the Servomotors do not operate for axis A and axis B.
• Monitor the ON/OFF status of the /HWBB1 and /HWBB2 signals.
If the ON/OFF status of the signals do not coincide with the display, the following must be
considered: an error in the external device, disconnection of the external wiring, short-circuit-
ing in the external wiring, or a failure in the SERVOPACK. Find the cause and correct the
problem.
Refer to the following manual for your SERVOPACK for details on the monitor.
