Product Description:

The SS2000-S40RE\1153MT is a stepper drive module produced by Kollmorgen within the SS2000 SLO-SYN Drives series. It operates as the electronic interface between a motion controller and a matched SLO-SYN motor, regulating phase current and commutation to achieve commanded position or velocity profiles. In automated packaging, pick-and-place, or small gantry axes, the drive supplies finely incremented current waveforms so the attached motor can move in precise step angles without resonance or missed steps.

This model accepts a bus input of 310 VDC, a level that provides adequate overhead for back EMF and switching losses while still fitting common rectified 220 VAC mains. The power stage can deliver up to 20 A per phase, allowing the connected motor to reach high dynamic torque without saturating the drive transistors. During rapid acceleration, the motor may draw as much as 53.30 A RMS, and the current-limited amplifier accommodates that peak demand to help prevent winding damage. Mechanical speed capability matches the motor’s rating of 3200 rpm, so full output can be reached without electronic derating. Under continuous stall or low-speed operation, the motor produces 164.40 lb-in of torque, giving machinery adequate holding force for indexing tables or vertical loads.

Short bursts require a higher torque margin, so the motor can generate 438.00 lb-in at peak for brief intervals before thermal cutback. Generated voltage rises with rotational speed at a rate of 58.80 V/KRPM, a back EMF constant the drive transistor bridge must overcome to maintain commanded current. The phase windings present 12.00 mH of inductance and 0.44 Ω of DC resistance, which affect current rise time and influence the PWM frequency strategy. Rated mechanical output is 5.50 kW, aligning electrical input with the motion work performed at nominal speed. Total rotor-and-housing mass is 35 lb, a weight that affects inertia matching and mounting provisions.
