Note   1. Connect a surge absorber as close to the servo motor as possible. 
 

  2. There is no polarity in electromagnetic brake terminals (B1 and B2). 

 

  3. Do not use the 24 V DC interface power supply for the electromagnetic brake. 

 

  4. Create the circuit in order to shut off by interlocking with the emergency stop switch.
