Precautions for Correct UsePrecautions for Correct Use
• Tighten the frame ground screw to a torque of 1.4 to 1.6 N·m (M5).
• Tighten the left terminal block screws to a torque of 2.0 to 2.4 N·m (M5). Exceeding the
maximum allowable torque for terminal block screws may cause damage to the terminal block.
• Tighten the fixing screw of the left terminal block cover to a torque of 0.3 to 0.5 N·m (M3).
• Tighten the right terminal block screws to a torque of 1.0 to 1.7 N·m (M5). Exceeding the
maximum allowable torque for terminal block screws may cause damage to the terminal block.
• Tighten the fixing screw of the right terminal block cover to a torque of 0.19 to 0.21 N·m (M3).
• 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.
