DM442 Anti-Resonance Stepper Motor Drive

DM442 Anti-Resonance Stepper Motor Drive

The DM442 is the latest generation of stepper motor drivers. This fully digital microstepping drive is based on a DSP with an advanced control algorithm that allows tuning of the current and position feedback loops in the drive and allows you to counter resonances that would otherwise stall the motor.

The driver is a current-chopping driver with a wide DC voltage input range and will suit a wide range of NEMA 17 to 24 motors. Microstepping allows you to achieve fine precision from your motor. The anti-resonance control algorithm produces smoother motion and allows higher top speeds than other microstepping driver systems.

Self-configuration and parameter auto-setup technology makes it easy to get the maximum performance from your motor. When the driver is tuned, the motor runs with much less noise, less heating and smoother movement than could be achieved with other drives on the market. These features make the DM442 excellent for all applications but are particularly advantageous for applications that require low-speed smoothness.

Without fine tuning, the drive will run at least as well as a pure-sinusoidal driver. To tune the driver further than the automatic tuning, you will also require the LSK-001 programming cable.
