2phase NEMA17 NEMA23 hybrid stepper motor driver DSP DC36V MC542 replace DM542

Product Name: 2 phase digital stepper driver MC542 for nema17 nema23 stepper motor MC542 is a new generation of digital control of two phase hybrid stepping motor driver based on DSP, according to user needs can be customized to any arbitrary Subdivision Current and rated current of less than 512 in value, due to increasing the internal motor parameter automatic recognition function, can according to the different motor with some operational parameters, the motor runs very smoothly. Low noise. function description Function Operation instructions Operating current setting The output current of the driver is set by the three dial switches of SW1-SW3, and the output current has 8 levels. For specific output current settings, refer to the drive panel instructions. Automatic half current function Set the auto semi current function of the drive through the SW4. The OFF indicates that the quiescent current is set at half of the dynamic current, and the ON represents the same static current as the dynamic current. For general use, the SW4 shall be set to OFF to reduce heating and improve reliability of the motor and actuator. After the pulse string stops, about 0.3 seconds or so, the current automatically reduces by 50% (actual value 55%), the calorific value theoretically reduces 65%. Microstep subdivide setting By the SW5-SW8 four dial switch set microstep subdivide, the total of 15 stalls microstep. When the user sets the subdivision, the drive should be stopped. The micro fine fraction set, please press the drive panel. Indicator light The drive has red and green lights. The green light is the power indicator lamp. When the drive is powered on, the green light is always on; the red light is the fault indicating lamp, and when the overvoltage and overcurrent faults occur, the trouble lamp is always on. After the fault is clear, the red light goes out. When the drive fails, only the power on and re enable to clear the fault. Signal interface PUL+ and PUL- are the positive and negative ends of the control pulse signals; the DIR+ and DIR- are the positive and negative ends of the directional signal; ENA+ and ENA- are the positive and negative ends of the enabling signals. Motor Interface The A+ and A- are connected with the positive and negative ends of the A phase winding of the stepping motor; B+ and B- are connected with the positive and negative ends of the B phase winding of the stepping motor. When the A and B two phase windings are switched, the motor direction is reversed. Power interface DC power supply, the input voltage range: 24~50VDC, power supply is greater than 100W Installation instructions Drive dimensions are: 117 * 78 * 34mm, the mounting hole distance is 111mm. It can be installed horizontally or vertically (vertical installation is recommended). When installed, it should be attached to the metal cabinet to facilitate heat dissipation. Application: Suitable for all kinds of motion control automation equipment and instruments, such as electronic processing and testing, semiconductor packaging, laser cutting and welding, laser printing, packaging machinery, engraving machine, marking machine, cutting machine, apparel plotter, CNC machine tools, automatic assembly equipment etc.. It is the first choice for users with low noise, high speed performance and competitive cost performance.
