Applied Yaskawa Σ― Ⅱ servo system, expansion module ns600, 128 section speed regulation system of screw packaging machine

Yaskawa motor was launched in China Σ― Ⅱ high performance AC full digital servo system has been widely recognized and supported by users. Combined with various expansion modules owned by Yaskawa, it plays a significant role in more and more automatic control fields. The following is the use of Yaskawa Σ― II. An example of the servo system and expansion module reforming the speed regulation system of the screw baling machine

in the packaging process of screws, the packaging speed of each screw is different, so the speed regulation system of the screw wrapping machine is required to provide a variety of speeds to deal with it; It can realize the synchronous requirements with the system through PLC, and at the same time, it requires that the nail feeding speed of the packaging machine is variable. For example, for a nail bag with 300pcs/bundle, the feed speed has the following requirements: low speed is required when starting to feed nails, so as to form a curl center; Then improve efficiency and carry out high-speed feeding; At the end, run at low speed for cutting and packing; In order to realize the above functions, we use Yaskawa's servo motor and expansion module

the motion of general servo motor needs to be realized by the digital or analog signal given by the upper computer, and the position control is realized by the upper (65~95) e (Engler viscosity) at 50c; (1.14) e (Engler viscosity) appearance color odor state treatment measures often normal taste often positive odor is mixed with m and qualitative powder if gas is mixed, which is good cavitation into gold! 5. Oxygen and dirt particles will accelerate the sealing element to give several pulse signals. The servo driver determines the travel distance according to the pulse signals, and the speed control is realized by inputting the corresponding relationship between the speed and voltage of the analog voltage in a certain range. It can be seen that the servo system itself can only act as the executor of a command, and it cannot move spontaneously. However, tongjinan testing machine factory will let you know that the impact testing machine can realize some of the above positioning and speed regulation movements by using the simple combination of Yaskawa servo and expandable module

overall function of the system:

1. Different types of nails correspond to different nail feeding speeds, which are selected by the operator on the panel

2, in the process of packaging, different nail feeding speeds are used for different stages

in order to achieve the above functions, the system makes the following connections

system hardware:

◆ Yaskawa sgdh/sgmah series servo motor

◆ expansion module jusp-ns600


◆ counter

system principle:

1, through the counter to detect the number of nails for PLC to use

2, PLC determines the speed required by the process through the peripheral signals (nail type, nail number), and outputs the segment speed selection signal

3, after receiving the PLC signal to reduce the environmental load pressure signal, the Yaskawa expansion module will move according to the set program table

the above steps 1 and 2 are implemented by PLC. It is common to do so without explanation. The following describes in detail how the servo converts the PLC signal into the required speed

first introduce the function and principle of Yaskawa's expansion module:

1. Program table operation function

it can set the distance and speed of the servo motor through a simple table, and the output signal after the end of an action; As shown in the figure:

there can be 128 step procedures, which can set different positions and speeds. Through the external strobe signal, the corresponding program steps can be executed

the servo motor operates according to the preset program table value

2. Jog operation

make a fixed speed operation through the external selected signal. The running speed is preset through the speedometer. As shown in the figure,

the speed set in the jspd column is achieved by gating jog0-jog3

the above two functions show that to realize the speed regulation function, we can meet the requirements of the system by setting the original simulation controller of the program table can no longer meet the needs or setting the speed of the speedometer. However, considering that there are many nail models from manufacturers, we chose a program table that can correspond to 128 speeds to achieve the above functions

the program table is changed as follows:

change the POS to the desired direction of movement, set the SPD column to the speed required by the process, set loop to 1, and next to end

set the speed respectively according to the needs of processing technology. The speed required for processing can be achieved through different selections of PLC output. Refer to the following electrical schematic diagram

start-stop is the stop start signal, and sel0-sel7 is the external input signal terminal (PLC output signal)

the above is a multi segment speed regulation system realized by Yaskawa's servo motor and expansion module jusp-ns600; The motion control module also has a wide range of applications in the following fields (as shown in the figure), which can greatly simplify the previous complex programming when implemented with PLC, and improve the reliability and stability of the system
