 The following are wiring precautions for the connector CN2.   
1)  Use shielded cable for wiring of the CN2 connector. 
2)  Be sure to use twisted cables for the pulse train input and the position feed back 
signals. 
Wiring length shall be short as possible. (2 [m] maximum) 
3)  These cables should be laid separately from the main power line.   
4)  Connect one end of the shielded cable to the frame ground. Refer to “3.3.3. Ground 
Connection and Wiring” for the way of connection.   
!
Caution  : Check for wiring mistake in the polarity of external power supply and 
shorting between connector pins. 
!
Caution  : Never connect the idle pins that are instructed as “Do not connect.”   
Do not treat the idle pins as instructed at the master controller (PLC, 
etc) side after you have connected all pins of the CN2 connector. 
◊ Connection of an idle pin that is clearly instructed not to connect 
may make the external noise easily affect the Driver Unit, and may 
lead to malfunction or breakdown of the Driver Unit.
