1.  Make sure that the power supply voltage is within the specified range of 

the servo drive unit. Failure to observe this could lead to damage or faults. 

2.  For safety purposes, always install a circuit protector, and make sure that 

the circuit is cut off when an error occurs or during inspections. Refer to 
Chapter 5 and select a no fuse breaker.  

3.  The wire size will differ according to each drive unit capacity. Refer to 

Chapter 5 and select the size. 

4.  For safety purposes, always install a contactor (magnetic contactor) on the 

main circuit power supply input. Large rush currents will flow when the 
power is turned ON. Refer to Chapter 5 and select the correct contactor.  

 

Drive the contactor via the relay from the CN9 connector's contactor control output (MC). Some types of 
contactors can be directly driven with 24VDC.
