Drive Guide and Drive Installation

Boot drive and installation drive?

The boot drive is the drive where the boot record and boot program are located; the internal drive is the drive placed inside the body. These are two classifications that may not overlap with each other. The boot drive may be an internal drive, such as a hard disk, SSD, etc., or it may be an external drive, such as a CD, USB flash drive, floppy drive, etc.

　

In the computer field, a drive refers to a disk drive. A storage area formatted with a file system and given a drive letter. The storage area can be a floppy disk, CD, hard disk, or other type of disk. Click the corresponding icon in Windows Explorer or My Computer to view the drive's contents. When the drive indicator light is on, do not remove the floppy disk from the corresponding drive or shut down the computer, otherwise the disk may be damaged. Distinguish them by naming the drives. Drive names are represented by a single English letter, with A and B representing floppy disk drives, C, D, and E representing hard drives, and optical disk drives generally represented by the letter H. In this way, there is what is often called "A drive, B drive, C drive, D drive". Each computer generally has only one optical disk drive, so it is often simply called "optical drive".

Select installation drive and boot drive?

Select the same partition as the boot drive and installation drive, select the version in the options below, and then click Start Installation to start the installation, and then wait until the progress bar runs out to automatically restart or manually restart OK

How to set up the driver for Hechuan driver?

1. Parameters that need to be set:

Note: For parameters numbered with *, their setting values ​​can only be modified successfully after the control power supply is cut off and restarted.

2. Modification of parameters:

1. Press the setting key S to enter d**.uEP;

2. Press the mode key M to enter the parameter Prr.*** , press the setting key S again to enter the parameter modification mode

How to change the CD drive to a DVD drive?

1. Run the "services.msc" command, open the service, select Shell Hardware Detection, change the item to "Automatic", and try starting it.

2. Try unchecking "Use this CDROM digital audio to play CDs" in the optical drive properties in the device manager;

3. Uninstall the CD-DVD driver from the task manager, and then I tried reinstalling step by step. Generally speaking, these are the problems. There is no problem with your optical drive hardware. It is just a problem with the settings and driver. I have checked little by little.

What is the difference between a closed-loop drive and a servo drive?

Closed-loop drives and servo drives are both devices used to control motors, but their working principles and application scenarios are different.

Closed-loop driver is a device that uses motor speed or position signal as feedback to realize motor control by controlling output voltage, current, etc. It has high control accuracy and response speed, and is suitable for controlling motor speed. Or scenes with high location requirements, such as industrial machinery, automated production lines, etc.

The servo driver is a device that controls the speed, position, torque and other dimensions of the servo motor through electronic control signals. It has higher control accuracy and stability and is suitable for applications that require higher positioning accuracy. and motion control precision occasions, such as high-precision processing machine tools, semiconductor equipment, etc.

Therefore, the main difference between the two is that the application scenarios and control requirements are different, but they are both important equipment for motor drive control.

How to upgrade the drive? How to upgrade the drive?

1. Taking the Win7 system as an example, right-click the computer icon on the desktop and select the "Management" menu;

2. After opening the computer management window page, double-click "Devices" on the left Manager" option, find the "Display Adapter" device, double-click to open the graphics device for which you want to update the driver;

3. In the opened graphics device properties page, click the "Driver" tab at the top, and click " "Update Driver" button;

4. In the pop-up window, select the "Automatically search and update driver software" option;

5. Finally, Windows will automatically search for the graphics card device online. The driver will automatically download and install the update if one exists.

Drive abnormality?

The two most common abnormal working states of the driver are phase error and overcurrent. Wrong phase is due to the wrong phase winding causing short circuit of the positive and negative poles of the same-phase winding of the stepper motor, short circuit between phases, short circuit of the winding to ground or short circuit of the winding to high voltage, etc.

Due to water intrusion and other reasons, the phase windings of the motor may be short-circuited to ground or to high voltage (short-circuit of same-phase winding A and A- or inter-phase winding A and B, A and B-, etc.). At this time, the current flowing through the driver will instantly increase, and the temperature of the H-bridge will rise rapidly, causing the motor to fail to work normally, or even burning the motor and driver, causing more serious consequences such as fire

What is the driver used for?

The function of the motor driver refers to the way to control the motor idle speed by controlling the rotation angle and operating speed of the motor to control the duty cycle.

The motor drive circuit can be driven by relays or power transistors, or it can be driven by silicon controlled thyristors or power MOS field effect transistors. In order to adapt to different control requirements (such as the operating current and voltage of the motor, the speed regulation of the motor, the forward and reverse control of the DC motor, etc.).

Drive classification?

A drive is a device that stores data in a computer. According to different storage media, drives can be divided into the following types:

1. Mechanical Hard Drive (MHD): Pass A drive that stores data by spinning magnetic material on the surface of a disk and using a read-write head to read and write data.

2. Solid State Drive (SSD): A drive that uses non-volatile memory such as Flash Memory to store data. It is faster and less noisy than a mechanical hard drive.

3. Optical Drive: A drive that uses laser to read and write data on an optical disc.

4. Flash Drive: A portable storage device that uses flash memory technology to store data. It is also commonly called a USB flash drive.

5. Tape Drive: A drive that uses magnetic tape to store data. Currently, it is rarely used.

6. Network Drive: A shareable storage device accessed through a network connection, such as a NAS (network storage) device.

7. Virtual Drive: A drive simulated by software, which is equivalent to a virtual disk and can be used to install operating systems, software, etc.

According to different connection methods, drives can also be divided into internal drives and external drives. Internal drives are installed directly inside the computer, and external drives are usually external devices connected to the computer through interfaces such as USB and SATA.

How to configure the driver if the LED light driver is broken?

The data can be viewed from the bad driver or Led light board. Led lamps are discrete. The voltage and power are marked on the lamp bead board. According to the voltage and power data, you can select the driver. The two are consistent and used.
