Note 1. There is no polarity in electromagnetic brake terminals B1 and B2.
2. BW is not available when a 1-phase power supply is used.
3. Configure the power supply circuit which turns off the magnetic contactor after detection of servo motor thermal.
4. For the cooling fan power supply, refer to (3) (b) in this section.
5. When using a servo motor with an electromagnetic brake, assign the electromagnetic brake interlock (MBR) to an
external output signal with parameters No.PD09 to PD11.
6. Do not use the 24VDC interface power supply for the electromagnetic brake.
7. Shut off the circuit by interlocking with the emergency stop switch.
