Product Description:

The SS2000D-6I is a microstepping drive produced by Kollmorgen within the SS2000 SLO-SYN Drives series. It controls hybrid stepper motors in material-handling, indexing, and light machine-tool axes where precise incremental motion is essential for repeatable positioning. Acting as an intermediary between a host controller and the motor windings, it interprets serial or analog commands and modulates phase currents so the mechanical load advances in smooth, low-vibration steps, simplifying motion integration in distributed automation.

The power section draws up to 7 A of line current and can supply a maximum of 6 A to each motor phase, supporting rapid acceleration without saturating the windings. An analog velocity or torque input is accepted through a 20 kΩ high-impedance port that is decoded at 10-bit resolution, permitting stable scaling from low to full speed. Micro-positioning accuracy is established by a base resolution of 1/64 step, translating to 12,800 microsteps per revolution when used with a standard 200-step motor, so backlash compensation routines can be executed in software instead of mechanics. The drive’s RS-485 interface supports as many as 32 nodes, while onboard logic clocks trajectories and closes current loops asynchronously from the host to minimize communication latency.

Internal electronics dissipate up to 50 W as heat, and this affects enclosure ventilation requirements for the unit’s 3.67 × 10.93 × 5.98 in footprint. Encoder feedback can be connected at sampling rates of up to 500 kHz per channel, with a regulated 5 VDC, 100 mA supply for the sensor. The asynchronous port transmits command packets at rates of up to 38,400 baud, and network timing is coordinated by a 16 MHz controller core that executes 16-bit math for profile generation. Overall mass is 7.75 lb, so the drive can be panel-mounted without additional bracing.
