4.6.4 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.
• Confirm that the SERVOPACK enters a hard wire base block state and that the servomotor does not operate
when the /HWBB1 and /HWBB2 signals are OFF.
• Check the ON/OFF states of the /HWBB1 and /HWBB2 signals with bits 0 and 1 of 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.
• 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.
