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;
