2. There is no polarity in electromagnetic brake terminals (B1 and B2).
3. When using a servo motor with an electromagnetic brake, always assign the electromagnetic brake
interlock (MBR) to CN1-12 pin by parameter No. PD18.
4. Do not use the 24VDC interface power supply for the electromagnetic brake.
5. Switch off the circuit interlocking with the emergency stop switch.
