**Features**

•When the instruction is turned on, the PLC obtains the number of pulses of the master axis (s1) according to the set response time (s3), calculates the average frequency within the response time, and calculates the output of the driven axis according to the set gear ratio Frequency and output pulse number, and output pulse (d1) and direction (d2). When the frequency of the driven axis is greater than the set maximum frequency, it will output according to the set maximum frequency.

46

47

•When the master axis (s1) uses the high-speed counter (HSC), the PLC internally obtains the number of external input pulses. Modifying the value of the HSC counter does not affect the judgment of the input pulse.

48

49

•When the master axis (s1) uses an ordinary double-word counter (LC), the PLC directly obtains the number of pulses from the LC register, and modifying the value of the register directly affects the judgment of the input pulse.

526

527

The traditional mechanical cam is composed of cam, follower and frame. A mechanical cam is an irregular part, generally an input part with a constant speed, which can transmit motion to a follower through direct contact, so that the action moves according to a set law. The follower is a passive part driven by a mechanical cam, and is generally an output part that produces unequal speed, discontinuous, and irregular motion.

528

529

ECAM is a software system that uses the constructed concave wheel curve to simulate mechanical cam to achieve the same relative motion between the camshaft and the main shaft of the mechanical cam system.

530

531

Compared with mechanical cams, ECAM makes the design of mechanical and electrical parts more and more simple. ECAM allows the equipment to be flexibly used in different templates and plate styles, and also allows the operation process and cycle of the equipment to be modified, either during the design phase of the equipment or after the equipment is formed. It reduces the complexity of the equipment, makes the equipment run more smoothly and doubles the production efficiency.

**A.Establish ECAM data**

536

537

{{id name="二、电子凸轮功能描述"/}}{{id name="1、建立电子凸轮数据"/}}LX5V provides 3 ways to establish ECAM data:

538

539

① Write table data to the table data area by DMOV instruction.

540

541

② Generate ECAM data automatically by ECAMTBX instruction.

542

543

③ Draw ECAM data with PLC Editor software.

544

545

**{{id name="2、主轴脉冲选择"/}}B.Spindle pulse selection**

546

547

The selectable spindles of LX5V series PLC are HSC, LC type and virtual time axis K.

548

549

Among them, external high-speed input uses high-speed counter, which supports single-phase single-count input\single-phase double-count input and biphase double-count input. As for the assignment of counters, refer to the instructions for high-speed counters in the PLC help.

550

551

When using HSC register (high-speed counter), the pulse of spindle is obtained internally. Modifying the value of the counter does not affect the cam to judge the actual pulse input quantity.

552

553

When using the normal counter LC, the pulse of spindle is obtained from devices. Modifying the value of the register will affect the judgment of the pulse of spindle .

554

555

When using the K type register, it means to use the internal virtual time axis, and the minimum unit is 100us, K1=100us, K10=1ms.

**(2) Function description**

602

603

When the contact M0 is turned on, the PLC activates ECAM function, but the ECAM function is not yet running at this time, it just initializes the parameters of the cam. It includes that D1000 to D1005, D1031, D1032 will be cleared and check whether the cam table is correct. After initialization, these registers still need to be set for control.

604

605

This instruction configures the relevant registers and required data for cam operation, and enables the function of ECAM, but the cam does not actually run. To actually enable the ECAM function, the relevant device in the cache address of the instruction (such as D1000 in the instruction) is also needed to control the start and stop of the cam.

606

607

If the instruction is disconnected, the cam stops working.

608

The following figure shows the ECAM data, where the spindle length is 50000, the output unit is the number of pulses, and the synchronization range is 20000 to 30000. When running into the synchronization zone, the synchronization terminal output can be used as a control signal. To create ECAM data, please refer to the ECAM data. Hardware circuit Y1 outputs pulse to connect to X0, and it means that the spindle input terminal receives the output pulse of Y1.

This example is to use the software PLC Editor2 to set the table.

**Instructions**

① When executing the program, the special register is set first. The set parameters are as follows:

697

698

A. Double word is composed of SD881 and SD880, the current position of Y0 is cleared to 0,

699

700

B. Start the high-speed counter HSC0 and configure it as a single-phase input to receive the high-speed pulse input of X0 (in this case, the pulse of X0 comes from the output pulse of Y1).

701

702

② SET M0 to start the ECAM, Y axis starts to perform variable speed movement. The main axis receives variable speed input pulse of Y axis, the slave axis outputs pulse according to the ECAM curve, and when the main axis position is 20000-30000 in each cycle, Y7 is ON state.

703

704

**✎Note: **Special registers must be set before the ECAM is started. Set the upper and lower limits of the synchronization position of the ECAM D2009 = 20000, D2011 = 30000; and set the number of the synchronization terminal Y D2008, and the synchronization output enable D2004-BIT0, an ECAM cycle is 50000 pulses and when the spindle position is 20000-30000 pulses (monitored by D2025 and D2026), the synchronization terminal is ON.

705

706

③ RST M0, the cam stops running.

723

724

1. At time T1, address 5=2, and aperiodic ECAM is started.

725

1. After the calculation of the time T2, the PLC actively sets the address 1-bit0=ON (the initialization of aperiodic ECAM is completed). At this time, the slave axis will not follow the movement of the master axis.

726

1. At time T3, the ECAM start signal is turned ON (when the external start signal is used), the slave axis will follow the spindle movement for one cycle according to the position relationship in the table.

727

1. After the cycle is completed at the position of time T4, the PLC will actively clear the state of address 1-bit0=ON, and the user can also judge whether the cycle is completed according to the state of address 1-bit1 to .

728

1. During the time T5, the user can choose whether to set the address 1-bit0=ON again through the program , for the purpose of completing the judgment next time.

729

1. Time T6/T7 position is to repeat the action of T3 to T4 again. **✎Note: **The interval between the rising edges of the cam start signal must be more than 0.5ms.

753

This example uses the software PLC EDITOR to ECam0. Please refer to 9.2.2.5 for the detailed steps of creating an ECAM curve. The Y1 axis of the hardware circuit outputs pulse and connects to the X0 axis input terminal, indicating that input terminal position of master axis is to receive the pulse output of Y1 axis as input.

**{{id name="_Toc973"/}}Operation steps**

756

757

① When the program is executed, set special registers first, and the set parameters are as follows:

758

759

A. The contents of SD880, SD881 and SD940, SD941 are cleared to 0

760

761

B. Set D1014=2 (repeat the form twice)

762

763

② Set M0: Configure and start the cam. When M0 is the rising edge, set D1003-Bit5 to use an external start signal; when D1005=2, Y1 outputs pulses, and Y0 axis has not output yet at this time.

764

765

③ The external signal X2 is triggered, and Y0 axis is output with the ECAM curve; the output stops after 2 cycles.

766

767

④ RST M0: Close the ECAM mode; if runs RST M0 when the ECAM is running, Y0 axis will stop output immediately.

Define the relationship between master axis and slave axis, which is called electronic cam table data. In the data input, the electronic cam table has two ways to express:

1195

1196

Method 1: The functional relationship between the adopter

1197

1198

Method 2: Use the point-to-point relationship of X and Y to obtain the electronic cam table in two ways:

1199

1200

Approach 1: According to the standard function relationship of the master and slave axis

1201

1202

Approach 2: According to the corresponding relationship between points measured in actual work.

1203

1204

The cam table can define multiple CAM curves. After the relationship is determined, the position of the slave axis can be obtained according to the position of the master axis.

The chart is mainly divided into 4 parts, namely the relative position of the master/slave axis, the relative speed of the master/slave axis, the relative acceleration of the master/slave axis, and the bottom data setting. The first three parts are used to display the CAM data set by the user. The horizontal axis is the main axis, and the vertical axis is the position of the slave axis, the speed ratio of the slave axis to the master axis, and the acceleration ratio of the slave axis to the master axis. The data setting area is introduced as follows:

1217

1328

In the feeding and cutting application, the traditional method is to use the stop-and-go method. The feeding shaft first walks to a fixed length, and then the cutting shaft moves again, and then the process of "feeding stop" and "cutting stop" is repeated. Disadvantages of the medium method. In the process of feeding shaft stop and stop, the required acceleration and deceleration can not improve the production efficiency. Therefore, the new method is to use the non-stop feeding method. Generally, there are two feeding and cutting methods: rotary saw and flying saw. The difference between the two is that rotary saw moves in the same direction, while flying saw moves back and forth, and the set CAM table curves are also different.

**{{id name="1.1飞剪动作说明"/}}(1) Description of rotary saw action**

1334

1335

1) Rotary saws control the cutting axis to rotate in the same direction, and cut when the tool touches the material. During this period, the feeding axis will continue to feed at a constant speed without stopping. The action and output stroke of rotary saw control are shown in the figure below:

1336

1337

①. Accelerate and move to the synchronization area from the beginning of the axis;

1338

1339

②. In the synchronization zone and the spindle at the same speed and output the cutting signal (CLR0);

1340

1341

③. After leaving the synchronization zone, the slave axis will decelerate and move back to the origin to complete a cycle of cutting. After knowing the stroke, the speed relationship can be drawn.

1342

1343

2) In the cutting process, the most important thing is speed synchronization. For example, when the cutting knife contacts the material, it must be synchronized with the material speed. If the cutting knife speed is greater than the synchronous speed during contact, a force that pulls the material forward will cause the material to be uneven. If the speed is lower than the material speed, it will appear. Blocking phenomenon.

1344

1345

3) The planning of the synchronization area will affect the operation of the actual equipment. If the synchronization area is larger in a cutting cycle, the acceleration and deceleration time will be smaller, which means that the equipment needs to be accelerated and decelerated in a short time. For motors and machines The impact of the cutter is very large, and it is easy to cause the servo over-current alarm and the equipment cannot operate normally.

{{id name="1.3.1概述"/}}1) Overview

1464

1465

Synchronization zone: At this time, the feeding axis and the cutter axis rotate at a fixed speed ratio (the linear velocity of the cutter head is equal to the linear velocity of the cutting surface), and the cutting of the material occurs in the synchronous zone.

1466

1467

Adjustment area: due to different cutting lengths, corresponding displacement adjustments are required. According to the cutting length adjustment zone, it can be divided into the following three situations.

1468

1469

Short material cutting: the cutter shaft first has a uniform speed in the adjustment area, and then decelerates to the synchronous speed.

1470

1471

Normal material cutting: In this case, the cutter axis accelerates first in the adjustment zone. Then decelerate to synchronous speed.

1472

1473

Long material cutting: In this case, the cutter shaft first accelerates to the minimum limit operating speed in the adjustment area, and then decelerates to the synchronous speed. After the cutter shaft makes one revolution, the cutter shaft decelerates to zero and stays for a while, then speed up and cycle operation. The longer the material length, the longer the residence time.

When setting the maximum limit magnification, synchronization magnification, and minimum limit operation magnification, the material length boundary is also determined. Several limit values are as follows:

1484

1485

①The speed of the shortest material (Lm1) satisfies: the actual maximum operating magnification = the maximum limit magnification, and the adjustment area is a constant speed + deceleration process.

Therefore, the length of the material determines the type of operation of the slave axis:

1501

1502

① When Lm1 ≤ L <Lm2, this is a short material, and its 0 ≤ actual maximum operating magnification ≤ maximum limit magnification

1503

1504

② When Lm2 ≤ L <Lm3, this is a normal material, and its minimum limit operation magnification ≤ actual maximum operation magnification ≤ maximum limit magnification

1505

1506

③ When L ≥ Lm3, this is a long material, and the actual maximum operating magnification = minimum limit magnification. There is a residence zone, the longer the material, the longer the residence time.

The flying saw system means that the feeding shaft will not stop while the system is cutting, so the camshaft must keep the same speed with the feeding shaft when cutting, and the same speed time must be enough for the cutter to complete the cutting and detach to safety s position. The flying saw camshaft will drive the cutter and the entire group of cutting mechanisms to move, so that it can maintain the same speed with the main shaft during cutting.

At the beginning, the camshaft stops at position 1, and then accelerates forward to position 2 to achieve speed synchronization, and continues to position 3, then decelerates and returns to position 4 in the opposite direction (assuming position 1 and position 4 are the same), and then repeat this action .

After leaving the synchronization zone, the speed will decrease and stop, and then return to the starting position. All the stroke feeding axes (spindles) have been feeding at a constant speed.

The stroke of the flying saw is divided into two parts: the following part and the returning part. The two moving distances must be the same. From the speed stroke point of view, that is, positive area = negative area.

1644

1645

During flying saw, you need to pay attention that the feeding will not stop during processing, so the processing axis must keep the same speed with the feeding axis, and the synchronization time must be enough for the equipment to complete processing and move to a safe position.

1646

1647

The stroke length of the synchronization area is also the processing time, which can be considered when planning the synchronization area. In addition, the planning of the synchronization area will affect the operation of the actual equipment. If the synchronization area is large in a cutting cycle, the acceleration and deceleration time will be smaller, indicating that the equipment needs to be accelerated and decelerated in a short time. For motors, machines, and cutters The impact is very large, and it is easy to cause the servo over-current alarm, and the equipment cannot operate normally.
