⒉Programming

The device has two programming methods, which are single-step programming and multi-step programming. User can set up programming according to actual demand.


①Single-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 Figure.

E21S Operation Manual

Step 2 Click向下键 , select parameter that needs to be set up, press numerical key to input program value, press下左键 to complete input.

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

Setting range of single step parameter is shown in Table.

E21S Operation Manual

Step 3 Press绿圆点 , system will execute according to this program, as shown in Figure.

E21S Operation Manual

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.

 ⒉Multi-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红P , switch to program manage page, as shown in Figure.

E21S Operation Manual

Step 3 Click 向左向下键向右, select program serial number, or input program number directly, such as input “1”. 

Step 4 Click 下左键, enter multi-step program setting page, as shown in Figure.

E21S Operation Manual

Step 5 Click向下键 , select multi-step programming parameter which requires set up, input setting up value, click下左键 , and the configuration takes effect. 

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

E21S Operation Manual

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

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

Multi-step parameter setting range is shown in Table.

Step 9 Click绿圆点 , system will operate according to this program, as shown in Figure.

E21S Operation Manual

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 axle position is 50.0mm, concession 50mm; 

● The second shear: X axle position is 100.0mm, concession 50mm; 

● The third shear: X axle position is 300.0mm, concession 50mm; 

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


Operation procedure is shown in Table.

E21S Operation Manual

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


⒊ Parameter setting

User can setup all parameters required for normal operation of the system, including system parameter, X axle parameter.

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

Step 4 Click 红P, return to programming constant page.


⒋Manual movement

In single-step mode, axle 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加号减号 or手指 to enter manual page, as shown in Figure.

Step 2 Click加号 , operate at low speed in increasing direction. 

            Click 减号, operate at low speed in decreasing direction. 

            Click手指 , click 加号at the same time, and operate at high speed in increasing direction (this operation is valid only when using frequency converter as the drive). 

            Click手指 , click 减号at the same time, and operate at high speed in decreasing direction (this operation is valid only when using frequency converter as the drive).

Step 3 Click红P return to single step parameter setting page.

Alarm

The device can detect internal or external abnormity automatically and send out alarm prompt. Alarm message is available on alarm list.

Step 1 On programming management page, click红P to enter programming constant page. 

Step 2 On programming constant page, click 向右to enter “Alarm history” page to view all alarm history.

As shown in Figure, the latest 6 alarms, alarm number and causes can be viewed on this page.
