5.3 Automatic Operation
Manual/automatic signal: at low
level, the controller is in
automatic mode.
In automatic mode, the height of the cutting torch is controlled
automatically
according to the set height by the user.
If press t
he key "
↑
" on the operation panel once, the set value of height will increase by
1; if press and hold
it down, the set value
of height will increa
se continuously in step of
1.
If press the key
“
↓
”
on the operation panel once, the set value of height will decrea
se by
1; If press and hold it down, t
he set v
alue of height will decrease continuously in step of
1.
6. Commissioning
6.1 Initial commissioning of heig
ht controller in capacitance detection mode
The height measurement in capacitance mode is to measure the distance bet
ween the
capacitance detection ring and
work piece or the height through
detecting the capacitance
between them thereby to
achieve height control.
When the capacit
ance-mode height measurement is adopted, the specific inductive
capacity
(SIC) between the capacitance detection ring and the work piece may affect the
height
measurement accuracy due to such ambient
factors as temperature, pressure, humidity,
gas composition and son on. In addition, there is serious non-linea
r relationship between
the capacitance value and the height
value. Microstep has developed the int
elligent
program of "one-keystro
ke height calibration
". Only one key needs to be pressed locally
to calibrate the height controller based on various ambient factors automatically; in the
meantime,
the display and control in high accuracy, high precision and
high linearity will
be achieved within 3-30mm.
In the
following cases,
height calibration
is required.
1. The height cont
roller is used for t
he first time;
2. The ambient
environment
of height controller cha nged;
