11.5 Validating Safety Functions
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 Panel Operator or Digital
Operator displays Hbb and that the Servomotor does not operate.
• 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 sections for details on the monitor.
9.2.3 I/O Signal Monitor on page 9-7
13.3.4 Safety Input Signal Monitor (Un015) on page 13-10
• Confirm that the EDM1 signal is OFF while in normal operation by using the feedback circuit
input display of the connected device.
