· This is a terminal for controlling the electromagnetic contactor (MC) for
external dynamic brake resistor (customer preparation). Please connect if
necessary.
· The applied voltage between DB1 and DB2 must be AC 300 V or less, DC

To use an external regenerative resistor (customer prepared), connect an
external regenerative resistor between P and B.
In addition, parameter setting is required for the regenerative resistor.
For details, refer to "Technical Reference - Functional Specification ".

*Tighten the Earth screw with a torque of M6: 2.4 to 2.6 N · m.
*Tighten the terminal block (upper side: control power supply, dynamic brake) screws with torque of M4: 0.7 to1.0 N · m.
If the tightening torque exceeds the maximum value, the terminal block may be damaged.
*Tighten the terminal block (lower side: main power supply, regenerative resistance, motor) screw with torque of
M6: 2.2 to 2.5 N · m. If the tightening torque exceeds the maximum value, the terminal block may be damaged.
*Tighten the fixing screw for the terminal block cover 1 (transparent) with torque of M3: 0.19 to 0.21 N · m.
*Tighten the fixing screw for the terminal block cover 2 (black) with a torque of M5: 2.0 to 2.5 N · m.
