When selecting the wire rod, please choose 600V PVC cable and the length should not 
longer than 30m. If the length exceeds 30m, please take the received voltage into 
consideration when selecting the wire size. Please refer to Section 3.1.6 for wire rod 
selection. 
 
NOTE
 
1.  The coil of brake has no polarity. The names of terminal 
identification are BRAKE1 and BRAKE2. 
2.  The power supply for brake is DC24V. Never use it for VDD,  
the +24V source voltage. 
3. () in servo motor model represents brake or keyway / oil seal. 
4. (△) in servo motor model represents encoder type.  
△ = 1: incremental, 20-bit; △ = 2: incremental, 17-bit;  
△ = M: magnetic.
