11.2.3 Resetting the HWBB State

Normally, after the Shutdown command is received and power is no longer supplied to the Ser-
vomotor, the /HWBB1 and /HWBB2 signals will turn OFF and the SERVOPACK will enter the
HWBB state. If you turn ON the /HWBB1 and /HWBB2 signals in this state, the SERVOPACK
will enter a base block (BB) state and will be ready to acknowledge the Servo ON command
(Enable Operation command).

If the /HWBB1 and /HWBB2 signals are OFF and the Servo ON command (Enable Operation
command) is received, the HWBB state will be maintained even after the /HWBB1 and
/HWBB2 signals are turned ON.
Send the Shutdown command to place the SERVOPACK in the BB state and then send the
Servo ON command (Enable Operation command).
