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.
