Precautions for Correct Use
 Tighten the terminal block screws 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 screws to the torque of 1.4 to 1.6 N•m (M5).
 Never connect an External Regeneration Resistor between the B1 and NC terminals

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 connected. When using an externally
connected Dynamic Brake Resistor, remove the short bar from
between DB3 and DB4.
This is the ground terminal. Ground to 10 Ω or less.
