The NC bus cables are connected from the NC to each drive unit so that they are laid in a straight line 
from the NC to the terminal connector (battery unit). And up to 7 axes can be connected per system. 
(Note that the number of connected axes is limited by the CNC. The following drawing shows an 
example with 5 axes connected.) 

 

CN1A  :  CN1B connector on NC or previous stage's drive unit 
CN1B  :  CN1A connector on next stage's drive unit or terminal connector (battery unit) 

 

 

Max. length of 30m from the NC to the terminal connector. 

Connect to the 
battery unit with a 
terminal connector 
or SH21 cable.

SH21 cable 

 

 
 

 

 

Wire the SH21 cable between the NC and drive unit so that the distance 
between the NC and terminal connector (battery unit) is within 30m. 

 

 

 

Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to 
section "8-1-1 Setting the rotary switch".) The axis No. has no relation to the 
order for connecting to the NC.
