Product Description:

The NEAT-310M is a microstepping drive manufactured by Kollmorgen as part of the NEXTSTEP Microstepping Drives series. Intended for industrial automation, the unit converts incoming AC power and host-controller pulses into finely metered phase currents that advance two-phase stepper motors in small, accurate increments. By inserting controlled current ramps between full steps, the drive reduces motor resonance and allows positioning systems, indexers, and light machining stages to reach higher resolution without mechanical gearing.

Beneath its DIN-rail enclosure, the drive uses a bipolar chopper output stage fed by a universal single-phase source of 115/230 VAC at the standard 50/60 Hz line frequency. A dedicated logic regulator provides +5 VDC for external encoders or sensors, isolating control electronics from the power section. Motion behavior is governed by a microstepping ratio of divide-by-10, a peak jog velocity of 327,680 steps/s, and a commanded acceleration ceiling of 9,830,400 steps/s². These limits let motion planners shorten cycle time while maintaining smooth starts and stops. Current feedback and dynamic pulse multiplication preserve torque linearity over the entire speed range.

Nonvolatile program space of 8 KB stores index routines that can be triggered through a 30 V, 25 mA parallel input bank, while a 24 VDC, 100 mA output channel transmits status signals. A form-C relay rated at 120 VAC, 3 A interfaces the drive with contactors or brakes, while a 5 A fast-blow motor fuse protects the power path against short circuits. When paired with a 0.9° motor, the controller attains 4000 steps/rev; with a 1.8° motor, it resolves 2000 steps/rev, with both values based on a step angle of 0.18°/step. Continuous operation is permitted at up to 95% relative humidity, allowing the drive to function in humid factories.
