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.

It supports cutting slit detection function to improve the stability of arc voltage tracking
In the cutting process, it monitors whether the arc is actually started in real time. If the arc
breaks in the middle, the height regulator will notify the CNC system in time and turn off the
arcing relay to avoid long-term arcing in the case of arc breaking.
In the process of automatic height regulating, it ensures that the actual arc voltage always
closely follows the set arc voltage, and there is basically no static difference.
In the process of automatic height regulating, it can still change the arc voltage setting
value to fine-tune the torch height in real time during the cutting process.
In the process of automatic height regulating, the collision signal can be fed back to the
CNC system to prevent the CNC system from controlling the cutting torch forward after the
collision.
After the cutting is completed, the height regulator automatically raises the cutting torch
torch, and the height can be arbitrarily set.
It supports multiple height regulators to work synchronously.

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.
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.
Gun lifting time：parameter range: 0-10, unit: s. It refers to the time when the
cutting gun automatically lifts after the cutting.
Manual speed：parameter range: 10-100, unit:%. 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: 10-100, unit:%. 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.
Automatic height regulating
After it is selected, the height regulator works in the automatic height regulating
mode. At this time, after the condition of automatic height regulating is met, the
height regulator will turn on automatic height regulating; when it is not selected,
the height regulator works in manual mode, and the height regulator will not
automatically perform height regulating.

Figure 4.3 Parameter importing interface
Parameter importing supports importing from an external U disk or from a local
hard disk, and supports to import parameter files with different file names.
The operation method of importing from U disk is basically the same with
importing from hard disk. When importing from U disk, you must first insert U disk
into the USB interface on the back of height regulator. The following is an example of
importing from a hard disk.
Move the cursor to the [F2 - Import from hard disk] button, and then press the [Enter] key
to enter the parameter importing interface; or press the [F2] key directly to enter the parameter
importing interface. As shown in Figure 4.4.
