Precautions for Correct Use Precautions for Correct Use
• Tighten the frame ground screw to a torque of 2.4 to 2.6 N·m (M6).
• Tighten the top terminal block screws to a torque of 0.7 to 1.0 N·m (M4). Exceeding the
maximum allowable torque for terminal block screws may cause damage to the terminal block.
• Tighten the bottom terminal block screws to a torque of 2.2 to 2.5 N·m (M6). Exceeding the
maximum allowable torque for terminal block screws may cause damage to the terminal block.
• Tighten the fixing screw of the terminal block cover to a torque of 2.0 to 2.5 N·m (M5).
• 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.
