(3)  Automatic operation & Feed hold switch 
This is the switch that performs the automatic operation in AUTO and MDA mode for 
CNC program or holds the axis feed during automatic operation. 
 
1)    Cycle start switch 
The available mode of cycle start is. 
     
It  can  be  used  to  start  the  automatic  operation  in  AUTO  mode 
regarding CNC machining program called by operator. 
The called program will be run automatically as soon as releasing 
the  cycle  start  switch  during  pressing  it  under  the  condition  of 
satisfying for automatic operation.  
And this switch can be used on the TSM screen of JOG mode. 
<LED state> 
Light : in case of Automation Operation of CNC 
 
 
Be  careful  that  program  will  be  activated  to  cycle  start  as  soon  as  pressing  this 
button under the state of satisfying the condition for automatic operation. 
Before  cycle  start,  be  sure  to  check  the  axis  stroke  etc.  for  preventing  from 
unexpected human accident and the machine damage. 
 
2)  CYCLE STOP switch 
This  switch  is  used  to  hold  the  axis  feed  temporarily  during 
automatic  operation.  When  pressing  this  switch,  the  auxiliary 
functions(M, S, T) during program execution will stop after its com-
pletion.  And  axis  feed  and  dwell  also  stop.  At  that  time,  the 
selection of machine data determines whether spindle and coolant 
stop or not. In order to release the hold state and restart automatic 
operation, press cycle start switch once. 
<LED state> 
Light :  In  case  that  the  automatic  operation  stops  and  the 
hold signal output comes out. However, in case of hold 
during  M,S,  and  T  code  execution,  LED  is  ON  and 
then automatically OFF by the completion of motion.
