Resetting The Hwbb State - YASKAWA SERVOPACK Sigma 7W Series Product Manual

5.2.3

Resetting the HWBB State

The following examples use the Σ-7W SERVOPACK with MECHATROLINK-III commands. If you
use a Σ-7C SERVOPACK, you will need to use Controller Section commands instead of MECHA-
TROLINK-III commands.
Important
Normally, after the SV_OFF (Servo OFF: 32 hex) command is received and power is no longer
supplied to the Servomotor, the /HWBB1 and /HWBB2 signals will turn OFF and the SERVO-
PACK 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
SV_ON (Servo ON: 31 hex) command.
