What are the types of two-phase four wire stepper motor drives?
2024-03-257910How many stepper motors can a 32 microcontroller control?
2024-03-23103201. Overtravel faultWhen the servo motor exceeds the soft limit set by the software or the hard limit set by the limit switch, an overtravel alarm will occur. Generally, the alarm content will be displayed on the CRT. According to the server maintenance manual, the fault can be eliminated and the alarm can be lifted.2. Overload faultWhen the load ...
2024-03-23102101、 Selection of stepper motor torque. The holding torque of a stepper motor is similar to the power of a traditional motor. Of course, there are also essential differences. The physical structure of a stepper motor is completely different from that of an AC/DC motor, and the output power of the motor is variable. Usually, the type of motor is selec...
2024-03-228620CNC equipment requires the use of servo motors because servo motors have characteristics such as high precision, high response, high speed, and high reliability, which can meet the requirements of high-precision control for CNC equipment. The servo system in CNC equipment generally consists of servo motors, encoders, controllers, etc. The servo mot...
2024-03-218320Viewpoint 1When the servo motor shakes at zero speed, it should be because the gain is set high, which can reduce the gain value. If there is a slight shaking during startup, the alarm will stop, and it is most likely due to incorrect motor phase sequence.Viewpoint 21. When the PID gain adjustment is too large, it is easy to cause motor vibration...
2024-03-209410The operating accuracy and output torque accuracy of servo motors are relatively high, mainly used in equipment with relatively high requirements for process accuracy, processing efficiency, and work reliability, such as:1. Mechanical industry: machining centers, CNC punching machines, bending machines, shearing machines, PLC program controllers,...
2024-03-199010Simply put, the main difference between servo motors and ordinary motors is:The servo motor has more precise positioning and feedback. Ordinary motors don't have them, they just turn on when powered on.1. Comparison of feedback methods between servo motors and ordinary motorsA servo motor can achieve precise control, allowing it to rotate as much...
2024-03-167310Servo motors are widely used in the field of automation control, such as in robotic arms and AGV vehicles, where there are varying numbers of servo systems. So, what are the future development trends of servos? Let's put it simply.1. Communicationalization.There are more and more servo motors of communication type. Compared to DC servo motors, AC...
2024-03-159010The abnormal noise of servo motors can be caused by various reasons, and the following are some common reasons:Bearing wear: Bearings in servo motors may wear out due to prolonged or improper use, resulting in abnormal noises. When bearings wear out, metal friction sound and noise will be generated, and bearings need to be replaced to solve the p...
2024-03-149310Manual control: Actually, it's just some simple switch quantity control. The movement of servo motors is mainly controlled through manual devices such as physical buttons, switches, or joysticks. The advantage of this method is that it is relatively easy to operate and is commonly used in the debugging process of some motors.Signal input control:...
2024-03-1314110When using a servo (Panasonic) to return to the origin in a recent project, if other axes are also moving, the Z-phase zero point signal received by the PLC is easily lost, resulting in abnormal return to the origin position. Later, upon checking the driver manual, it was discovered that the GND of the Z-phase zero point signal needed to be connect...
2024-03-1111320What speed curve has the highest stability when the servo motor starts or stops. The commonly used trapezoidal velocity curve has significantly poor stability. It is said that according to the 5th degree curve acceleration, the motor torque will not experience sudden changes, and the motor stability is also more reliable?
2024-03-099310How many W servo motors can drive a 300kg load to move horizontally?
2024-03-0711720Why do we still need to develop stepper motors when we have servo motors?
