Power supply
of cooling fan
Note 1. There is no polarity in electromagnetic brake terminals B1 and B2.
2. When the power supply for the cooling fan is 1-phase, BW does not exist.
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 section 3.10.2 (3) (b).
5. When using a servo motor with an electromagnetic brake, assign the electromagnetic brake interlock (MBR) to external
output signal in the parameters No.PA04, PD13 to PD16 and PD18.
6. Shut off the circuit by interlocking with the emergency stop switch.
