  XPTHC-4 Brake adjusting and sensitivity adjusting 

DO NOT ADJUST THE RED SEALED! 

XPTHC-4’s logic control is controlled by the SCM, it can be set on the operation panel, 

and to raise up the high performance’s request, it uses the artificial circuit to control the 

drive parts, so it can be adjusted the “R6012”(Brake-ADJ) and “R501”(SEN-ADJ) for the 

motor’s brake and sensitivity. See Fig2-3 shows:

 

 

 

 

 

 

 

 

 

 

 

Fig 2-3 Brake and Sensitivity adjusting 

1

To  brake  adjusting  of  the  motor  is  to  achieve  fast  braking  when  operate  the  THC 

manually, then it can avoid the up/down distance due to the inertia, and makes the up/down 

height more accuracy.   

This  THC  (XPTHC-4)  is  to  achieve  the  fast  braking  by  Plug-Braking.  It  can  be  set  via 

adjusting  the  Resister  “R6012(Brake-ADJ)”.  While  It  has  been  adjusted  well  before 

ex-factory, doesn’t need to adjust by user, unless longtime use/component aging etc. When 

user  adopts  the  motor  control  voltage  to  control  the  limit  instead  of  using  the  THC’s  limit 

switch, it’s no effective of the fast braking function, please choose the proper limit method. 

2

Sensitivity of THC decides the cutting accuracy. 

THC sensitivity setting: 

Sensitive increases on anti-clockwise, decrease on clockwise 

 

Note:If sensitivity is too high, torch would shake, please test it carefully.

 

XPTHC-4  is  tested  on  the  2800mm/min  lifter, 

so  for  1000mm/min—3000mm/min  speed 

lifter,  user  no  need  to  commission  it.  If  user  need  the  speed  over  3000mm/min,  then 

could decrease the sensitivity a little lower according to the cutting situation(If it shake 

during cutting, please decrease the sensitivity). 

 

Sensitivity  matters  to  the  quality  of  lifter.  If  the  lifter  can  lift  torch  up/down  on  with  DC 

motor Power Supply below 3V, it is qualify lifter for XPTHC-4.
