The DM542 is a fully digital stepper drive designed using an advanced DSP control algorithm based on the latest motion control technology. A unique level of system smoothness has been achieved, providing optimum torque and zero average instability. Its auto-identification and motor parameter setting function allows you to quickly tune the optimum mode with different motors. Compared to traditional analog drives, the DM542 can drive a stepper motor with significantly lower noise, lower heating and smoother movement. Its unique features make the DM542 the ideal choice for demanding applications. 
 Features Anti-resonance provides optimum torque and zero volatility at medium level Auto-identification and tuning technology of motor parameters, offers optimal responses with different motors Multi-Stepping allows low resolution stepping input for higher microstepping output, thus offering smoother motor movement 15 selectable microstepping resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000 l soft start without jump when switched on l input voltage 18-50VDCL 8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A l Pulse input frequency up to 200 kHz, TTL compatible and optically isolated input l automatic no-load current reduction Suitable for 2-phase and 4-phase motors l Supports PUL / DIR and CW / CCW modes l Overvoltage, overcurrent protection Applications Suitable for a wide range of ballasts motors, from NEMA size 17 to 34. Can be used in various types of machines such as XY tables, engraving machines, labeling machines, laser cutters, grippers and so on. in particular, adapt to the required applications with low noise, low heating, high speed and high accuracy. 
 Heat elimination L Reliable operating temperature of the driver should be <70 ℃ (158 ℉), and the engine operating temperature should be <80 ℃ (176 ℉); L It is recommended to use automatic idle current mode, namely, the current will automatically decrease to 50% when the engine is running, stops to reduce heating the driver and heating the engine; L It is recommended to install the driver vertically to maximize the radiator area. Use forced cooling method to cool the system as needed.
