Product Description:

The SS2000D3 is a microstepping drive produced by Kollmorgen as part of the SS2000 SLO-SYN Drives series. It translates incoming step-and-direction pulses into regulated phase currents so a two-phase stepper motor can advance smoothly at commanded rates. Within an automation cell, the unit is mounted near indexers, pick-and-place tables, or small gantries, where its role is to supply controlled energy to the motor while interpreting high-speed logic from a PLC or motion controller. The device operates as a stand-alone amplifier that needs only logic-level inputs, AC mains, and motor leads.

The drive accepts single-phase service at an AC input of 5 A and internally rectifies it to a DC bus potential of 180 VDC, which is the rail used by its chopper stage. Output current can be adjusted between a floor of 0.5 A and a ceiling of 3.0 A via on-board DIP switches, permitting thermal matching to different motor frame sizes. Pulse streams up to 1 MHz are decoded without loss when suitable differential or single-ended logic is present. A 250 V, 8 A fuse safeguards the input, and average power dissipation is limited to 35 W to reduce cabinet heating. Three motor terminals accommodate 4-, 6-, or 8-lead windings so both series and parallel coil arrangements can be driven.

Motion resolution ranges from a coarse 200 pulses/rev full-step mode to a fine 50,000 pulses/rev microstep setting, selected through front-panel switches for application-specific smoothness. The input interface recognizes pulses as narrow as 0.4 µs, enabling accurate positioning even from high-speed counters. Coil compatibility extends from 8 mH to a maximum of 64 mH, letting the unit support both low- and high-inductance motors without exceeding di/dt limits. The aluminum chassis measures 63 mm in width, while the depth and height are 142 mm and 244 mm, respectively, fitting common panel or DIN positions without occupying excessive enclosure space.
