introduction：sl0-2D temperature relay sl0-2The temperature relay is activated by the temperature rise of the surrounding environment or the temperature rise caused by the heat generated by the current itself,Because the relays on-resistance is very small,Therefore, the temperature rise caused by the thermal effect of the current is also small,Temperature rise is negligible compared to ambient temperature,Therefore, the operating temperature and recovery temperature of the temperature relay are generally detected by controlling the change of the ambient temperature. sl0-2Temperature relay precautions：

introduction：Stepper motor is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement，It is the main executive element in modern digital program control system，Extremely widely used。。In the case of non-overload，Speed of motor、The position of the stop depends only on the frequency and number of pulses of the pulse signal，It is not affected by changes in load，When the stepper driver receives a pulse signal，It drives the stepper motorTurn a fixed Angle in a set direction，call“Step Angle”，Its rotation is carried out step by step at a fixed Angle。The amount of angular displacement can be controlled by controlling the number of pulses，So as to achieve the purpose of accurate positioning；At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency，Thus to achieve the purpose of speed regulation。
