5.11.4 Confirming Safety Functions

When starting the equipment or replacing the SERVOPACK 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 panel operator or digital operator dis-
plays "Hbb" and that the motor 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 must be considered.
Find the cause and correct the problem. For details, refer to 8.7 Monitor Display at Power ON.
• 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.
