Precautions for Correct UsePrecautions for Correct Use
• Tighten the terminal block screws to a torque of 0.75 N·m (M4) or 1.5 N·m (M5).
• If the torque for terminal block screws exceeds 1.2 N·m (M4) or 2.0 N·m (M5), the terminal
block may be damaged.
• Tighten the fixing screw of the terminal block cover to a torque of 0.2 N·m (M3).
• Tighten the ground screws to a torque of 0.7 to 0.8 N·m (M4) or 1.4 to 1.6 N·m (M5).
• Do not connect any External Regeneration Resistors between B1 and NC.

terminals
Normally B2 and B3 are shorted. Do not short B1 and B2. Doing so may
result in a malfunction.
If there is high regenerative energy, remove the short-circuit bar between
B2 and B3 and connect an External Regeneration Resistor between B1 and
B2.
