Note 1. There is no polarity in electromagnetic brake terminals B1 and B2.

2. There is no BW when the power supply of the cooling fan is a 1-phase.

3. Configure the power supply circuit which turns off the magnetic contactor after detection of servo m otor 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 external

output signal in the parameters No.PD09 to PD11.
