used for fine plasma cutting.The device is easy to operate, stable in performance and

complete in function. The height regulating motor supports stepper motors or servo

motors in position control mode, as well as traditional DC motors.The device utilizes

the basic constant current characteristics of the plasma power source to detect changes

in the plasma torch height by detecting changes in the plasma arc voltage, and to

control the height between the torch and the workpiece in real time. It is suitable for

height control of plasma power torches with constant current characteristics or

constant current characteristics within a certain voltage range.

The device is light and portable, easy to operate, easy to use, with menu or

graphical prompts for all operations, realizing fool operations. All button switches are

user-friendly and comfortable.

The device adopts high-performance ARM chip and ultra-large-scale programmable device FPGA,

runs multi-tasking real-time operating system, and combines software interpolation mode and hardware

interpolation mode to make the lifting motor with the position control mode run more smoothly and

reliably with high reaction speed.

Figure 4.1 The common parameters in position control mode

Positing detection time：parameter range: 0 – 30, unit: s. If the time used by the

positioning detection is exceeded, the positioning success signal or the collision

signal is not detected, the height regulator prompts the positioning detection

timeout alarm and stops the positioning.

Lowering distance with high speed when positioning：parameter range: 0-2000,

unit: mm. If the cutting gun coordinate is less than the value during the lowering

process when positioning, the positioning speed is the automatic speed. If the

cutting gun coordinate is greater than the value, the positioning speed is the low

speed when positioning. The cutting gun coordinates can be read from the main

interface of the system.

Low speed when positioning：parameter range: 100-30000, unit: mm/min.

During the positioning process, the cutting gun automatically switches to low

speed when lowering distance exceeds the lowering distance with high speed when

positioning,improving the positioning accuracy

Positioning height：parameter range: 0-20, unit: mm. The height at which the

cutting gun rises when positioning is also the height of plasma arcing.

Arcing detection time：parameter range: 0-30, unit: s. After the arcing relay is

closed, if the effective arc voltage or the Successful arcing input signal is not

detected within this time ( whether the arc voltage or the Successful arcing input

signal is detected is determined by the Successful arcing detection mode ),then

the system will prompt the arcing detection timeout and stop the arcing.

Key-holing height：parameter range: 0-55, unit: mm. The height of the cutting gun

from the steel plate. when key-holing.

Key-holing time：parameter range: 0-10, unit: s. The Key-holing time starts from

the Successful arcing .

Turn off the height regulating after key-holing：Turn off the height

regulating after key-holing: parameter range: 0-20, unit: s. This time starts

from the end of the key-holing time, during which the height regulator will

not regulate height.

Cutting height：parameter range: 0-20, unit: mm. After the key-holing time is over,

the cutting gun needs to lower to the cutting height.

Set arc voltage：parameter range: 30-300, unit: V. The setting value of the arc

voltage when cutting. Note that this parameter is the set value in arc voltage mode,

and the set arc voltage in height mode is acquired in real time during the cutting

process.

Over cutting slit arc voltage threshold：parameter range: 4-20, unit: %. This

parameter is the percentage of set arc voltage. During the normal cutting process,

if the actual arc voltage ≥set arc voltage*( 1+Over cutting slit arc voltage

threshold), the height regulator will be considered currently in the cutting slit

state, and the height regulator will turn off the height regulating. For example, if

the set arc voltage is 120V and the over cutting slit arc voltage threshold is set to

10%, if the actual arc voltage exceeds 132V,the height regulator will turn off the

height regulating. Note: The detection of the cutting slit is also affected by the

detection parameters of the over cutting slit arc voltage change rate in the system

parameters. If the over cutting slit arc voltage change rate detection is not selected,

once the actual arc voltage exceeds the over cutting slit arc voltage threshold, the

height regulator will turn off the height regulating immediately; if the over cutting

slit arc voltage change rate detection is selected, the actual arc voltage exceeds

the over cutting slit arc voltage threshold, and the arc voltage changes quickly,

then the height regulator will turn off the height regulating. If the arc voltage

changes slowly,the height regulator is not considered to be a over cutting slit state.

Increase sensitivity：parameter range: 1-100, unit: %. Increasing the sensitivity

is to increase the sensitivity of the motor response. The higher the sensitivity, the

more sensitive the motor response is, but it is not too large,otherwise, the cutting

gun will appear jitter during the height regulating. In actual use, according to the

cutting speed and the inertia of the lifting body, it can be regulated to the height

where the motor does not jitter and can be quickly regulated.

Number of collisions allowed：parameter range: 0-100, unit: none. During the

cutting process, if the number of collisions exceeds this parameter, the height

regulator collision output will send a collision signal to notify the CNC system.

Each time a collision occurs, the height regulator will raise the gun and the raising

height is the cutting height.

Lifting gun delay：parameter range: 0-3, unit: s. After the cutting is finished,

the height regulator will delay the time, then raise the gun and the raising height of

the gun is Lifting gun height.

Lifting gun height：parameter range: 0-200, unit: mm. After the

cutting is completed, the cutting Lifting gun delay is performed, and

then the cutting gun lifts the height.

Manual speed：parameter range: 100-30000, unit: mm/min. It refers to the

lifting and lowering speed of the cutting gun when the height regulator is in the

stop state. When in the stop state, press the [gun lifting], [gun lowering] button or

provide the input signal of the gun lifting/gun lowering from the input port, and

the cutting gun is moving at manual speed.

Automatic speed：parameter range: 100-30000, unit: mm/min. The lifting and

lowering speed of the cutting gun when the height regulator is in the non-stop state,

including the lowering with high speed when positioning, lifting when positioning,

key-holing lifting, key-holing lowering, lifting the gun when the cutting is

completed, the cutting gun return to zero, and so on.

Height regulating mode

Height regulating mode is divided into arc voltage mode and height mode.

Arc voltage mode：during the height regulating process, the set arc voltage

is used to regulate the height.

Height mode：after enabling the height regulating, the height regulator

first collects the arc voltage of the current height.

Arcing mode

Arcing mode is divided into normal mode and direct arcing.

Normal mode：the normal mode is the process of normal arcing, key-

holing, and cutting.

Direct arcing：after the Successful arcing , the height regulator directly enters the

cutting state without going through the key-holing process.

Figure 4.2.The common parameters in DC motor control mode

Positing detection time：parameter range: 0 – 30, unit: s. If the time used by

the positioning detection is exceeded, the positioning success signal or the

collision signal is not detected, the height regulator prompts the positioning

detection timeout alarm and stops the positioning.

Lowering time with high speed when positioning：parameter range: 0-30, unit:

s. If the positioning time is less than this value during the lowering process when

positioning , the lowering speed when positioning is automatic speed, and if the

lowering time when positioning exceeds the value, the positioning speed is low

speed when positioning.

Low speed when positioning：

parameter range: 10-100, unit: mm/min. During the positioning process, the cutting

gun automatically switches to low speed when lowering distance exceeds the

lowering distance with high speed when positioning,improving the positioning

accuracy.

Positioning height：parameter range: 0-20, unit: s. During the positioning

process of the height regulator, if it receives a successful positioning or collision

input signal, and it starts positioning and lifting. It refers to the set time that is set

from the moment when the successful positioning or the collision input signal is

disconnected to the moment when positioning height is lifted.

Arcing detection time：parameter range: 0-30, unit: s. After the arcing relay is

closed, if the effective arc voltage or the Successful arcing input signal is not

detected within this time ( whether the arc voltage or the Successful arcing input

signal is detected is determined by the Successful arcing detection mode ),then

the system will prompt the arcing detection timeout and stop the arcing.

Key-holing lifting time：parameter range: 0-10, unit: s. It refers to the key-holing

lifting time when dynamic key-holing.

Key-holing time：parameter range: 0-10, unit: s. The time required for key-holing.

Key-holing lowering time：parameter range: 0-10, unit: s. The key-holing

lowering time when dynamic key-holing.

Turn off the height regulating after key-holing：parameter range: 0-5,

unit: s. This time starts from the end of the key-holing lowering time,

during which the height regulator will not regulate height.

Set arc voltage：parameter range: 30-300, unit: V. It refers to the setting value of

the arc voltage when cutting.
