’  3.12  Input  for  electronic  handwheel-servos 
3.12.1  Input  for  electronic  handwheel  HR  150  or  HR  250 
For  hand-assisted  servo,  a separate  connector  input  is provided  in  addition  to  the  transducer  inputs.  The 
electronic  handwheel  may  be connected  to  this  input  via  a cable  of  max.  20  m.  In  the 
ELECTRONIC  HANDWHEEL  mode  both  the  handwheel  and  the  external  direction  buttons  are  active. 
Pre-selection  of  the  axis  to  be  moved  is via  the  axis-keys  X,  Y,  Z  or  IV.  Pre-selection  of  traversing  range  /R.P.M. 
of  handwheel  is via  input  of  factors  1 -  10.  Depending  on  the  rapid  traverses  programmed  in  the  machine 
parameters,  the  factors  for  fast  traverse  can  be  inhibited.

3.12.2  Input  for  dual  handwheel  unit  HE  310 
A  separate  input  is provided  for  this  handwheel  unit.  The  portable  unit  incorporates  two  handwheels  with 
axis  selection  buttons  and  emergency  stop  button.  Simultaneous  movement  of  the  machine  axes  X-Y,  X-Z, 
Y-IV  or  IV-Z  is possible. 
A  terminal  block  is located  adjacent  to  the  flange  input  socket  for  the  handwheel  unit  HE  310  on  the  rear  of 
the  unit.  To  activate  the  “EMERGENCY  STOP”  of  the  handwheel  unit,  the  external  “EMERGENCY  STOP”- 
circuit  must  be  connected  via  terminals  1 and  2. 
3.13  Input  for  touch  probe  systems 
The  control  versions  TNC  151/TNC  155  are  eq.jipped  with  an  input  for  the  3D-touch  probe  systems 
HEIDENHAIN  510  (triggering  touch  probe  for  infra-red  transmission)  or  HEIDENHAIN  110  (triggering  touch 
probe  for  cable  transmission). 
Touch  probe  system  110  comprises  a touch  probe  TS  110  and  adapter  electronics  unit  APE  110.  The  touch 
probe  system  510  consists  of  an  (infra-red)  touch  probe  TS  510  and  a transmitter/receiver  unit  with  adapter 
electronics  unit  APE  510  (dimensions  and  cable  lengths,  see operating  manual,TS  110,  TS  510). 
Both  touch  probe  systems  are  used  for  automatic  datum  finding  and  electronic  alignment  of  workpieces. 
If  the  touch  probe  is to  be  used  on  machines  with  automatic  toolchanger,  the  touch  probe  system  510  should 
be used.  Either  system  may  be  used  on  machines  with  manually-operated  toolchanger.
