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

These terminals are used to control the MC for externally connected
dynamic brake resistance. The output contact specifications are 1 A max. at
300 VAC/100 VDC max.
Connect them if required.
Normally DB3 and DB4 are shorted.
When using an externally connected Dynamic Brake Resistor, remove the
short bar from between DB3 and DB4.
This is the ground terminal. Ground it to 100 Ω or less.
Function
These are the output terminals to the Servomotor.
Be sure to wire them correctly.
