NOTE
 
1)  CN1 terminal signal, HSIGN (pin 46), /HSIGN (pin 40), HPULSE (pin 38), and /HPULSE (pin 29) are 
  provided in ASDA-A+ series only. In ASDA-A series, the function of these terminals is “NC”, which 
  means “No Connection”. 
2)  The terminals marked "NC" must be left unconnected (No Connection). The NC terminals are used 
  within the servo drive. Any outside connection to the NC terminals will result in damage to the drive 
  and void the warranty!
