Hard Wire Base Block (Hwbb) State - YASKAWA SGD7S-1R9D Product Manual

• If a failure occurs such as a Power Module failure, the Servomotor may move within an elec-
tric angle of 180°. Ensure safety even if the Servomotor moves.
The rotational angle or travel distance depends on the type of Servomotor as follows:
• Rotary Servomotor: 1/6 rotation max. (rotational angle calculated at the motor shaft)
• Linear Servomotor: 50 mm max.
• The HWBB does not shut OFF the power to the SERVOPACK or electrically isolate it. Imple-
ment measures to shut OFF the power supply to the SERVOPACK before you perform main-
tenance on it.
