Back gauge can be controlled.
Cut-angle can be controlled.
Cut-gap can be controlled.
Stroke time can be controlled.
Intelligent positioning control.
Unilateral and bidirectional positioning which eliminates spindle clearance effectively.
Retract functions.
Automatic reference searching.
One-key parameter backup and restore.
Fast position indexing.
40 programs storage space, each program has 25 steps.
Power-off protection.

Operation Instruction

2.2 Programming

The device has two programming methods, which are single-step programming and

multi-step programming. User can set up programming according to actual demand.

2.2.1 Single-step programming

Single-step programming is generally used for processing single step to finish work piece

processing. When controller is power on, it will automatically enter single-step program page.

Operation steps

Step 1

After starting up, the device will enter setting up page of single-step program

automatically, as shown in

Step 2

Click

, select parameter that needs to be set up, press numerical key to input program value, press

to complete input.

[Note] Parameter can only be set when Stop indicator is on.

Setting range of singe step parameter is shown in

Step 3

Press , system will execute according to this program, as shown in

Operation example

On single-step program page, program back gauge position to 80.00mm, retract distance to 50mm, concession waiting time to 2s, and work piece to 10.

Operation steps are shown in

2.2.2 Multi-step programming

Multi-step program is used for processing single work piece of different processing steps, realize consecutive implementation of multi-steps, and improve processing efficiency.

Operation step

Step 1 Power on, the device enters to single-step parameter set up page automatically.

Step 2 Click, switch to program manage page, as shown in

Step 3 Click , select program serial number, or input program number directly, such as input “1”.

Step 4 Click , enter multi-step program setting page, as shown in

Step 5 Click

, select multi-step programming parameter which requires set up, input setting up value,

click , and the configuration takes effect.

Step 6 In completion of set up, click, enter step parameter set page, as shown in

Step 7 Click,select step parameter that needs to be set up, input program value,click,and the setup takes effect.

Step 8 Clickto switch over between steps. If the current step is the first step, click to enter the last page of step parameter setting; if the current step is the last one, click to enter the first page of step parameter setting.

Multi-step parameter setting range is shown in

Step 9 Click, system will operate according to this program, as shown in

Operation example

[Background] One work piece requires processing 50 as shown below;

First shear: 50mm;
Second shear: 100mm;
Third shear: 300mm;

[Analysis] according to work piece and technological conditions of machine tool:

First shear: X axis position is 50.0mm, concession 50mm;
The second shear: X axis position is 100.0mm, concession 50mm;
The third shear: X axis position is 300.0mm, concession 50mm;

Edit processing program of this work piece on No. 2 program.

Operation procedure is shown in

[Note]

In completion of multi-step programming, you should back to starting step before

launching the system; otherwise, the program will start position processing at current

step.

Press left and right direction key to circulate page turning and browsing among all step

parameters.

Program can be called and revised again.
In completion of processing all work pieces (50 in the example), the system stops

automatically. Restart directly will start another round of processing 50 work pieces.

2.3 Constant

User can setup the general parameters for the device, including the metric or imperial and the language.

Step 1 On program management page, click，click to enter programming constant page, as shown in below. On this page, programming constant can be set.

Range of programming constant setup is shown in

Step 2 Input password “1212”, click, to enter Teach Page, as shown in

Step 3 Step up parameter, parameter setup range is shown in

<How to Teach>:

You can directly measure the positions of slider and back gauge. If the measurement is difficult, you can program and operate any one process, and then measure the accomplished workpiece.

Step 4 Click, return to programming constant page.

2.4 Manual movement

In single-step mode, axis movement can be controlled by pressing key manually. This method helps user to adjust machine tool and work piece.

Step 1 On single step parameter setup page, click

,

or

to enter manual page, as shown in

Step 2 According to your actual requirement, following the above table to adjust the position of the axis.

A-axis and G-axis are controlled by the relays, press to move them at low speed in increasing direction; press to move them at low speed in decreasing direction. Button is of no effect on them.

If the drive mode of X-axis is common motor:

<Note>: When the system is on run status, the operation of manual adjustment is just valid for the X-axis.

If the drive mode of the corresponding axis is frequency:

Step 3 Click return to single step parameter setting page.
