Part 1 – Operation Instruction

1.2 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.

1.2.1 Single-step programming

Caution: When the parameter X or Y displays on the page, please do not enter the RUN page or Manual page, unless you have reset the teach function of X-axis or Y-axis.

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 2-2.

Figure 2-2 Single-step program setting page

Step 2 Press , select parameter which 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.

Step 3 Press , system will execute according to this program, as shown in Figure 2-3.

Figure 2-3 Single step operation page

Operation example

On single-step program page, program bending depth to 100.0mm, back gauge position to
80.00mm, retract distance to 50mm, concession waiting time to 2s, holding time to 3s, work
piece to 10.
Operation steps are shown in Table 2-2.

1.2.2 Multi-step programming

Caution: When the parameter X or Y display on the page, please do not enter the RUN page, unless you have reset the teach function of X-axis or Y-axis.

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 displays the single-step parameter page automatically.
Step 2 Press , switch to program manage page, as shown in Figure 2-4.

Figure 2-4 Program management page

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

Step 4 Press , enter multi-step program setting page, as shown in Figure 2-5.

Figure 2-5 Multi-step

Step 5 Press , select multi-step programming parameter which requires set up, input
setting up value, press , and the set up takes effect.
Step 6 In completion of set up, press , enter step parameter set page, as shown in Figure 2-6.

Figure 2-6 Step parameter set page

Step 7 Press , select step parameter that needs to be set up, input program value, press , and the setup takes effect.
Step 8 Press to switch over between steps. If the current step is the first step, press to enter the last page of step parameter setting; if the current step is the last one, press to enter the first page of step parameter setting.

Multi-step parameter setting range is shown in Table 2-3.

Step 9 Press , system will operate according to this program, as shown in Figure 2-7.

Figure 2-7 Multi-step programming operation page

Operation example

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

■ First bend: 50mm

■Second bend: 100mm

■Third bend: the other direction 300mm
[Analysis] according to work piece and technological conditions of machine tool

■First bend: X axis position is 50.0mm; Y axis position is 85.00mm, concession 50mm

■The second bend: X axis position is 100.0mm; Y axis position is 85.00mm, concession 50mm

■The third bend: X axis position is 300.0mm; Y axis position is 85.00mm, concession 50mm
Edit processing program of this work piece on No. 2 program.
Operation procedure is shown in Table 2-4.

<Note>

■ In completion of multi-step programming, return to start 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), system stops automatically. Restart directly will start another round of processing 50 work pieces.

1.3 Parameter setting

User can setup all parameters required for normal operation of the system, including system parameter, X axis parameter and Y axis parameter.
Step 1 On program management page, press to enter programming constant page, as shown in Figure 2-8. On this page, programming constant can be set.

Figure 2-8 Programming constant page

Range of programming constant setup is shown in Table 2-5.

Step 2 Input password “1212”, press to enter the Teach Page, as shown in Figure 2-9.

Figure 2-9 System parameter setting page

Step up parameter, parameter setup range is shown in Table 2-6.

<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 3 Press , return to programming constant page.
—-End

1.4 Manual adjustment

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, press or to enter manual page, as shown in Figure 2-10.

Figure 2-10 Manual page

Step 2 According to your actual requirement, following the above table to adjust the position of the axis. – If the drive mode of the corresponding 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 Press return to single step parameter setting page.
—-End

Part2 – 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, press to enter programming constant page.
Step 2 On programming constant page, press to enter “Alarm history” page to view all alarm history.
As shown in Figure 3-1, the latest 6 alarms, alarm number and causes can be viewed on this page
