SK 135E – Decentralised motor starter
Many applications, including those in the field of material handling require electronic starting and stopping of the drive units. NORD has developed the new, innovative motor starter SK 135E for this. Due to its versatility, not only motor starting functions, but also gentle starting or reversing mode are possible.Extensive monitoring functions e.g. protect against overheating. Thanks to the I2t triggering characteristic, a motor protection switch is not required. The integrated mains filter of the motor starter SK 135E (with motor-mounting) meets the very highest EMC requirements.

- Q: The green lights flashing in the motor drive are flashing, and the red light is not bright
- The red light indicates that the power is switched on and the green light indicates that there is a pulse instruction. Whatever the lights are on, what's your problem?
- Q: Step into the motor drive red light for the cause of the failure
- Rezai MA860H stepper motor drives, ac and dc all can use power supply, with super wide voltage range, shall not exceed 90 v voltage is highest, the lowest not less than 24 v, Suggestions for 28-80 - v voltage range; It can be used in the 57, 85, 86 series and 110 series. There are 16 types of microsteps, the maximum number of steps is 51200Pulse/rev. The current range is 2.4 to 7.2 A, with A current of 8 and A current of 0.6 A. Automatic half flow, overpressure, over-current protection. The resai MA860H step motor drive has two red and green lights. The green light is a power indicator, and the green light is always bright when the driver is on.
- Q: Why do the ac servo motors drive?
- Common ac motor speed is 1400 RPM, why is 1400, because of the general power supply is 220 v, 50 hz, namely phase transform is 50 times per second, and usually is 4 pole motor, namely transform one revolution of the two phase, coupled with the ordinary ac motor is not synchronized, is ac asynchronous motor, speed than theory is so 50/2 * 60 = 1500 slowly, so is usually around 1400 RPM. Thus, the speed of the motor can be changed by changing the frequency of the power supply. The corresponding controller for a general motor is called a converter. Servo motor control more complex, need to change the frequency, voltage, current, in order to achieve the motor speed, torque, position of comprehensive control, servo drive is doing this. The servo motor is only responsible for how much frequency and voltage you give me, and I do what I do. The frequency, the voltage change, the change in the direction are all changed by the servo controller. Servo controller without logic control ability, in addition, if you need servo motor slow turning first, then faster, then to stop somewhere, inversion, and so on, these signals are in the charge of the upper controller of the servo controller, such as PLC, such as motion controller. And the PLC said, I'm going to change the speed, the servo controller gets the signal, and the frequency one is changed, and the expression on the servo motor is the change in velocity. That's roughly what it means.
- Q: What is the difference between the actuator 3 phase 220 and the single phase 220
- The servo motor can control the speed, the position precision is very accurate, can convert voltage signal to torque and speed to drive the control object. Servo motor rotor speed controlled by the input signal, and can be rapid response, in the automatic control system, is used as actuators, and has a small electromechanical time constant, high linearity, initiating character such as voltage, can convert the received electrical signal to the motor shaft angular displacement or angular velocity on output. Divided into two major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform.
- Q: How the servo driver works
- Advantages of servo to the system:1, the speed of adjustment is wide High positioning accuracy Have enough transmission rigidity and high speed stability Quick response, no overtones In order to guarantee the quality, productivity, and in addition to require a higher positioning accuracy, also requires good fast response characteristics, which requires command signal tracking response is faster, because the numerical control system at the time of starting, braking and acceleration for addition, subtraction is large enough to shorten the transition time of feeding system, reduce the contour error of transition. Low speed torque, overload ability Generally speaking, the servo actuator is more than 1.5 times the overload capacity in minutes or even half an hour, and can be over 4 ~ 6 times over in a short period of time without damage. High reliability Requirements of nc machine tool feed drive system, high reliability, good stability and strong environmental adaptation, such as temperature, humidity, vibration, and strong anti-interference ability.
- Q: How many drivers do you need for a few steps?
- The problem to analyze the actual situation, look at your control requirements, the machine work in stepper motor coil most energized to lock the motor shaft, shaft braking motor does not move, even if has the external force, such as hard to turn the motor shaft axis did not move if broken drive motor will move at this moment, so step motor which has no accuracy. Stepper motor drives are cheap now if you know the lower working principle of stepper motor is a stepper motor coil electricity xun sequence, and understand the microcontroller programming make a stepper motor driver circuit board so cheaper. Single chip and motor drive cost can be as low as a few yuan. There is a subdivision of the online bay, which drives 20 yuan for the power of the current, which can be bought with a dedicated drive chip. But that's a lot of knowledge.
- Q: This step into the power of the motor drive the two wires! thank you
- AC, AC, AC, AC, AC, AC and zero The following VAC 18-60v and AC AC can be sure that the driver is an alternating current, which should have a stabilized rectifier circuit Because the AC is neither positive or negative, only direct current is required to distinguish, so it has two AC If there is a distinction, he will use L N to indicate that if it is direct current, he will use VCC and GND If you want direct current, you can also direct VCC to the first AC, GND on the second AC If it doesn't work, you can answer it in reverse, you can, because it has a rectifier and a stable circuit
- Q: I have a dc brushless motor with a brushless motor drive motor
- The brushless motor is different from the brushless motor line that I touched before, and it's not easy to tell you exactly how to do it. But you can ask the seller to ask the correct answer, if the answer is correct still cannot function normally, the consideration is other problem.
- Q: How to select the driver after the step motor is selected
- You put your step motor models. Phase. Current. And lead number hair come over, I help you to select drive, the drive model is all on my side.
- Q: What is the principle of subdivision of step motor drive?
- Used in stepper motor step Angle can not meet the conditions, the subdivision driver can be used to drive the stepper motor, the principle of subdivision driver is by changing the size of the adjacent (A, B) current, to change the synthesis of the Angle of the magnetic field to control the step motor running. So current control technology is the key to the breakdown drive.
