Warnings:
Please read and strictly comply with the following instructions before operating the product, thus to assure the designed product control accuracy and prevent any damage and accident.
Installation must be carried out by certified technical personnel with relevant experiences. Please thoroughly read the instructions before starting installation. Make sure the local power supply satisfies the required specifications. Installation, plugging or unplugging power cord are prohibited when the power switch is on. The product should be positioned far away from any heat source if possible. The controller shell must be grounded well to avoid electric shock or affecting the controller. The work piece must be well grounded too and maintain a good connection with the controller shell for assured accuracy of height control.
Note: If the controller shell and the work piece are not properly grounded, the height controller will not work normally.
Please handle the product with care and make sure no impact or shock; otherwise, damage to the product might be incurred.
Never try to disassemble the product or modify its internal construction;
otherwise, accident or fault might occur.
Terminology Definitions
One-keystroke height calibration: In capacitance height measurement mode, the specific inductive capacity between the capacitance detection ring and work piece may affect the accuracy of height
measurement due to temperature, pressure, humidity, gas composition and many other ambient factors. In addition, the serious non-linear relationship exists between capacitance value and height value. Microstep has developed the intelligent program of "one-keystroke height calibration". Only one keystoke will automatically set the product based on various ambient factors. And within the range of
3-30mm, high accuracy, high precision and high linearity is possible in display and control.
High speed zone: When the difference between the actual height and the set height is relatively big, the cutting head will advance towards the set value at the highest speed in order to reach the set value the soonest; this travel zone is called high speed zone.
intime, butoscillation may be caused
Speed regulating zone: If the cutting head reaches the set value at a high speed, severe oscillation may be caused and the height control is unstable. In order to achieve a smooth transition, the speed regulating zone is set. This zone is located between the high-speed zone and the dead zone. In this zone, when it is far away from the set value, thecutting head will move at a higher speed; otherwise, at a lower speed. The range value of this zone is adjustable. If it is set too big, the transition is smooth, but the tracking time is too long; if it is set too small, the tracking is conducted in time, but oscillation may be caused easy.
Dead zone: Within a certain height range, the height of the cutting head will not be adjustable any more. The range is called dead zone. If
the dead-zone range is set too wide, the control precision will be too low; if it is set too narrow, the cutting head may oscillate up and down easily. An appropriate value of dead zone will not only guarantee the control precision but also generate no oscillation.
The advanced height linear calibration technology makes absolute height display and control possible when the distance between the cutting nozzle and work piece is within 3 ~ 30mm in the capacitance mode under for automatic height control in unit of millimeter and display accuracy of ± 0.1mm.
Integration of mechanical lifting device and height controller Detector, controller and drive are highly integrated with adjustable stroke up to 10cm.
All Digital Technology
Circuit uses SMD technology without any adjustable devices; all digital control technology ensures high product reliability.
Simple and convenient linearization calibration
The feature of "one-keystroke height calibration" guarantees that in any circumstances, the user only needs to press one key to calibrate the absolute height measurement and achieve linear height measurement.
Applicability in tough environment
The shell uses tamper-proof, waterproof and moisture-proof aluminum box sealed design, particularly applicable to the severe environment of high temperature or high electromagnetic interference from flame cutting or plasma cutting operation.
Various interfaces easy to use.
The interface is simple and easy to control. It is suitable for any flame cutting and plasma cutting CNC system or using alone.
