Stepping drive application Drive Notes SC248M, SC288M, SCD2680M, SC2240MA, SC2340MA, SC2440MA (B, C, D), SC2680MC (D, G, H), SC28110MA drive, internal use unique control circuit, adapted to four, six or eight qualifying motor, class drive with low noise, high precision segmentation, vibration and other advantages, especially for the smooth operation of the motor in the entire frequency spectrum. The unique design of the control circuit, a good balance between high and low performance of the motor, the motor output torque at high speeds than using the general drive more than 30%; low-speed operation, has a good breakdown of positioning accuracy and stability while the drive to reduce heat about 50%. SC series stepper motor drive control circuit With this unique, its overall performance in the domestic leading position. SC3660MA, SC35220MA, SC36110MA, SC37220MA three-phase hybrid stepping motor drive. Three-phase hybrid stepper motor is a stepper motor in the new family member, the first launch by the German hundred Benguela, these motors have little vibration, low noise, high-speed performance, high-speed output torque, etc., just launched on by users praise, has replaced the five-phase two-phase stepping motor of the potential, but adapted drive expensive price make the use of certain industries has been limited. Dual Technology has introduced the three-phase hybrid stepping motor driver, a very clear price advantage, expand the applicability of the industry. Class drives are used constant torque, vector and subdivision, its performance reached the level of similar foreign products, in addition, thanks to our technology is a hardware breakdown, the overall anti-jamming capability of the drive, precision and subdivision real-time processing capability has further improved, it is a good cost-effective products. High-precision segmentation, internal frequency doubling technology, drive technology and high-end segments of internal frequency technology is currently the lead. Subdivision up to 480 segments, and set up two groups of 32 block segments to choose from. And to develop any number of subdivisions within 480 according to user needs. Internal use of high-speed dedicated chip, ensuring at high micro-step breakdown of each is accurate. Internal frequency technology means that the user control can not be issued in the case of high-frequency drive on its own software, the low-frequency signal can be subdivided user input processing, which can only be issued by a lower frequency controller is also cause the motor to run smoothly at low settings segments, to drive and use high subdivision same effect. High reliability, high frequency of response. sckjmotor series stepper motor drive seal using surface mount (SMT) are all famous manufacturers of high-quality components, and processed on automated equipment, resulting in the processing sectors to eliminate the quality problems. In terms of the principle of the selection of power devices are: rated power on the drive and then leave for more than 50% margin, thus reducing the drive in many unexpected damage, such as power fluctuations or improper operation and so on. Maximum response frequency of up to 200kpps more. Overvoltage protection, when 20% of the input voltage exceeds the drive rated voltage, over-voltage protection circuit works. Overvoltage protection circuit discharge circuit, overvoltage long it will blow the fuse. Wrong phase, overcurrent double into a series of stepper motor drive design-phase and overcurrent protection circuit. When the motor is connected with the drive-phase motor runs extremely abnormal, the drive will be seriously damaged in a short time using this protection circuit can protect the drive from damage. Experiencing abnormal motor should be switched off power supply, check the power supply and the motor and the drive wiring is normal. Static protection current control when stepping pulse stops over 100ms, the motor coil current is automatically halved (non-adjustable) or 20% -80% (adjustable). Phase memory function: the newly developed three-phase hybrid stepping motor drive: sc35220ma, sc37220ma increase the phase memory function, namely: the input pulse stopped more than five seconds, the drive automatically when the motor phase memory, re-power or MF signal from the effective When the change is invalid, the drive automatically restore motor phase. SC Series drive is constant angle and constant torque subdivision-type drive, the drive voltage DC and AC high voltage and low voltage, 4, 6 or 8 outlet adapter current 8A or less, the outer diameter of 42-130mm (corresponding to each other) of various types of two phase three-phase hybrid stepper motor. The internal drive uses a unique control circuit, the circuit can be used to reduce the noise of the motor, the motor runs more balanced, high-speed performance of the motor can be increased by 30%, while the drive heating can be reduced by 50%. Widely used in mobile, shifting on the conveyor, engraving machine, laser marking machine, laser engraving machines and other high-resolution numerical control equipment, medium-sized CNC machine tools, packaging machinery, high-resolution large and medium-sized CNC equipment ??? Features: High performance, low price with a 12/8 shift angle constant torque subdivision, up to 200 segments with a unique control circuit maximum response frequency of up to 200Kpps stepping pulse stops over 100ms, the coil current is automatically reduced by half Bipolar constant current chopping mode optically isolated signal input / output 1. SC Series drive is optimized to the latest third-generation MUC and DSP, easy setup and flexible wiring simple, user-friendly interface; 2. sckjmotor drivers stable and reliable quality, the application surface is very wide , many high-end facilities with the present members, experienced more than a decade of stable operation of the test. Input signal through the optical isolation to ensure reliable built-in high-speed optocoupler conduction, require current drive capability control signal at least 15mA. Internal drive has a current limiting resistor in series with the optocoupler, when the input signal voltage is higher than 5V, current limit can be based on external needs Series Resistance R. + When 5V: R1 = 0, R2 = 0; + when 12V: R1 = 510Ω, R2 = 820Ω; + when 24V: R1 = 1.2KΩ, R2 = 1.8KΩ. Driver output signal via opto isolated output drive current of 50mA. Shenzhen double-Technology Electronics Co., Ltd. / stepper drive application Drive Precautions
