Today we will share the operation manual of E21 NC Controller for Press brake machine, It can help the operator to use the machien in a better and easy way. The operator shall read through this manual and know operation requirements before using this controller. E21 controller provides complete software control and the operator can pick it up as soon as possible.
E21 is specially used in the press brake machines, it can largely reduce the machine cost and keep the machine accuracy wihtin the standard requirements. The main features are as follows:
Operation panel is shown.
Functions of panel keys are described in Table.
E21 controller adopts a 160*160 dot matrix LCD displayer. The display area is shown below.
Title bar: display relevant information on the current page, such as its name, etc.
Parameter display area: display parameter name, parameter value, and system information.
Status bar: display area of input information and prompt message, etc.
The paraphrases of shortening on this page are as shown in Table.
Basic operation procedure: Basic switch over and operation procedure of the device is shown in Figure.
The E21 has two programming methods, which are single-step programming and multi-step programming. Users can set up programming according to actual demand.
Single-step programming is generally used for processing a single step to finish workpiece processing. When the controller is power on, it will automatically enter a single-step program page.
Operation steps
Step 1 After starting up, the device will enter setting up the page of the single-step program automatically.
Step 2 Press
select parameter which needs to be set up, press
numerical key to input program value, press to complete input.Setting range of singe step parameter is shown in Table.
Step 3 Press
, the system will execute according to this program, as shown in Figure.
Multi-step program is used for processing single workpiece of different processing steps, realize the consecutive implementation of multi-steps, and improve processing efficiency.
Operation steps
Step 1 Power on, the device displays the single-step parameter page automatically.
Step 2 Press
, switch to the program manage page, as shown in Figure.
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.
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.
Step 7 Press, select step parameter that needs to be set up, input program value,press, and the setup takes effect.
Step 8 Pressto switch over between steps. If the current step is the first step, press to enter the last page of the step parameter setting; if the current step is the last one, press to enter the first page of the step parameter setting. The multi-step parameter setting range is shown in Table.
Step 9 Press, system will operate according to this program, as shown in Figure.
Step 1 On program management page, pressto enter programming constant page, as shown in Figure,On this page, programming constant can be set.
Step 2 Range of programming constant setup is shown in Table
Step 3 Input password “1212”, pressto enter the Teach Page, as shown in Figure.
Step 4 Step up parameter, parameter setup range is shown in Table.
<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 5 Press, return to programming constant page.
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, pressto enter programming constant page.
Step 2 On programming constant page, pressto 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.
Alarm history and message is shown in Table
