Normally, short out the circuit between B2 and B3.
When a trip happens due to a regenerative load protection error, open the circuit
between B2 and B3 and connect an external regenerative resistor (prepared by
customer) between B1 and B2.

There are 2 grounding terminals.
Connect the one terminal to ground, and the other to the E terminal of a motor.
Do not connect more than one wire to a grounding terminal.
• Refer to section 9-3 for the tightening torque of the screw.
• Tighten the fixing screw of the terminal block cover with a torque 0.2 N•m or lower.
