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 motor thermal.
4. 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.
