The DM422C is a versatility fully digital stepping driver with advanced control algorithm. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. The self-test and auto-configuration technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives on the markets.Its unique features make the DM422C an ideal solution for applications that require low-speed smoothness.Features:Anti-Resonance, provides optimum torque and nulls mid-range instabilityMotor self-test and parameter auto-setup technology, offers optimum responses with different motorsMulti-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performanceMicrostep resolutions programmable, from full-step to 102,400 steps or revSupply voltage up to and36 VDCOutput current programmable, from 0.3A to 2.2APulse input frequency up to 75 KHzTTL compatible and optically isolated inputAutomatic idle-current reductionSuitable for 2-phase and 4-phase motorsSupport PUL or DIR and CW or CCW modesOver-voltage, over-current, phase-error protectionsApplications:Suitable for a wide range of stepping motors, from NEMA frame size 14 to 23. It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its unique features make the DM422C an ideal solution for applications that require low-speed smoothness.Specification:Model: DM442CRated voltage: 24 (V)Speed of response frequency: 200 (KHz)Fit range: 42 series stepper motorWeight: Approx.104g or 3.7ozPackage list:1 x Stepper Motor Controller Driver
