YASKAWA SGM series Safety Precautions

• Before starting operation with a machine connected, change the settings of the
switches and parameters to match the machine.
• Do not radically change the settings of the parameters.
• Install limit switches or stoppers at the ends of the moving parts of the
machine to
prevent unexpected accidents.
• For trial operation, securely mount the Servomotor and disconnect it from the
machine.

ccording to a setting in the SERVOPACK. The coasting distance will
change with the moment of inertia of the load. Check the coasting distance
during trial operation and implement suitable safety measures on the machine.
