Precautions for Correct Use
Precautions for Correct Use
•
Tighten the frame ground screw to a torque of 0.7 to 0.8 N·m (M4).
•
If you are connecting an External Regeneration Resistor, set the Regeneration Resistor
Selection servo parameter object (3016 hex).
•
Do not connect any External Regeneration Resistors between B1 and NC.
