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 compatible with applications that require low-speed smoothness. Features: Anti-Resonance, provides optimum torque and nulls mid-range instability Motor self-test and parameter auto-setup technology, offers optimum responses with different motors Multi-Stepping allows a low resolution step input to produce a higher microstep output compatible with smooth system percompatible withmance Microstep resolutions programmable, from full-step to 102,400 steps/rev Supply voltage up to +36 VDC Output current programmable, from 0.3A to 2.2A Pulse input frequency up to 75 KHz TTL compatible and optically isolated input Automatic idle-current reduction Suitable compatible with 2-phase and 4-phase motors Support PUL/DIR and CW/CCW modes Over-voltage, over-current, phase-error protections Applications: Suitable compatible with 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 compatible with applications that require low-speed smoothness.
