Struggling to operate your E21 press brake efficiently? Discover the ultimate guide to mastering its operation and boosting productivity with ease.

To operate an E21 press brake machine, start by setting the desired bending parameters using the controller. Secure the material properly and initiate the bending process following safety guidelines. Ensure regular maintenance and tool inspections for optimal performance. This guide simplifies the process, ensuring safe and precise operations for consistent results.

Ready to explore the detailed step-by-step process? Let’s dive into the full operation manual now.

E21 Introduction

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

Operation panel is shown.

Functions of panel keys are described in Table.

Single Interface

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.

Operation Procedure

Basic operation procedure: Basic switch over and operation procedure of the device is shown in Figure.

Single-step programming

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 Pressselect parameter which needs to be set up, pressnumerical 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 programming

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.  

Parameter setting

Users 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, 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.

Parameter setting

Important passwords: In addition to the above mentioned Password “1212” to access the teaching interface, there are a few passwords to help you better use the E21 system.

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, 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
