Precautions for Correct Use Precautions for Correct Use
• Tighten the terminal block screws to the torque of 1.5 N·m (M5) or 2.5 N·m (M6).
• If the torque for terminal block screws exceeds 2.0 N·m (M5) or 3.0 N·m (M6), the terminal
block may be damaged.
• Tighten the fixing screw of the terminal block cover to the torque of 0.4 N·m (M5).
• Tighten the ground screw to a torque of 2.4 to 2.6 N·m (M6).
• Do not connect any External Regeneration Resistors between B1 and NC.
