2.4 Motor drive current
This system adopts the integrated motor driver chip with protection function, it has perfect
over-current, Over temperature protection.
The current peak of motor drive can be up to 5A.
2.5 Working process
The cutting process with the initial positioning
When art start signal which it connect by CNC is IHSAON, THC can start IHS at first: torch
can decline until collision has happened. Then torch can be promoted to the original location
level and THC can send a commend to make arc start work, it make arc start relay close, plasma
power source start arc start. After arc start is working successfully and piercing delay time is
over, THC send a successful signal of arc start to CNC. CNC start cut, if THC is working in the
automatic allow state and CNC has sent auto control height signal, THC can work in the
automatic control height state. During torch work, if user pressed the button namedAUTO,
THC can quit allow condition automatically. Auto control height is stopped, and torch height
remain the same. If user pressed the button namedAUTOagain, THC will recover allow
condition automatically. THC can continue control height automatically. After torch has
accomplished, CNC close IHSAON signal, THC can auto make torch promote a height which
we set.
The cutting process without the initial position
When art start signal which it connect by CNC is EXAON, THC can not start IHS and send a
commend to make arc start work straight. It make arc start relay close, plasma power source
start arc star. After arc start is working successfully, and piercing delay time is over, THC send
a successful signal of arc start to CNC. CNC start cut, if THC is working in the automatic allow
state and CNC has sent auto control height signal, THC can work in the automatic control height
state. During torch work, if user pressed the button namedAUTO, THC can quit allow
condition automatically. Auto control height is stopped, and torch height remain the same. If
user pressed the button namedAUTOagain, THC will recover allow condition automatically.
THC can continue control height automatically. After torch has accomplished, CNC close
IHSAON signal, THC can auto make torch promote a height which we set.
