Product Description:

The SS2000I is a programmable stepper drive and motion controller produced by Kollmorgen as part of the SS2000 SLO-SYN Drives series. Designed for panel mounting in industrial machinery, it generates high-speed step and direction pulses, sequences acceleration, and manages deceleration for two independent stepper axes. Within an automation cell, the unit coordinates motor motion so that packaging, labeling, or positioning stations follow precise timing derived from internal profiles rather than external servo feedback.

Power is supplied through a wide input range of 90-265 VAC at mains frequencies of 50/60 Hz, allowing the same hardware to operate on single-phase utility lines worldwide. Internal logic and field terminations are energized by a dedicated I/O rail rated at 24 VDC, and the controller sources up to 0.75 A on that rail for sensors or contactors. Motion is executed in open-loop mode, so motor position is inferred from the commanded step count rather than encoder feedback. Separate acceleration and deceleration ramps let the programmer tailor jerk limits, and three selectable velocity profiles, trapezoidal, S-curve, or hyperbolic, shape speed transitions to match load inertia. Application code is stored in battery-backed RAM, holding up to 400 lines that execute without external PCs. Two rotary BCD switch banks permit immediate selection of resident programs or system parameters when the drive is offline.

Each move can control up to 2 motion axes, but the channels are triggered one at a time to prevent cross-coupling. Commanded steps leave the processor through a pulse generator rated at 48 MHz, which supports microstepping frequencies far beyond typical belt or lead-screw requirements. Registration inputs allow the controller to resynchronize the path to printed marks with a tolerance of ±1 microstep, and there are 16 digital inputs for limit switches, sensors, or interlocks alongside eight digital outputs for relays. Serial connectivity is offered through RS-232 or RS-485, operating at a default rate of 9600 baud for parameter download and status reporting, while mark capture latency remains low because all I/O is processed locally.
