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.
