Product Description:

The digifas 7202-SPS is a servo amplifier module produced by Kollmorgen within the DIGIFAS 7000 Servo Amplifiers series. It conditions high-voltage DC bus energy and meters current to a connected brushless motor, allowing closed-loop torque or velocity control on automated machinery. By integrating logic-level sequence control through its onboard SPS section, the unit removes the need for a separate PLC in compact motion axes.

The power stage operates from a DC link of 560 VDC and can continuously deliver 2.8 Arms while supporting momentary surges up to 5.6 Arms for acceleration events. An output stage clock of 8.33 kHz and a current-loop bandwidth of 1 kHz provide rapid current modulation so the motor follows command profiles with minimal lag. Motors with inductance as low as 15 mH can be driven without instability, and a residual voltage drop of 5 V keeps copper losses low. Ten digital inputs draw only 7 mA each and are routed through the SPS I/O section, which terminates on a Mini Combicon 3.81 mm, 12-pin connector rated for 1.5 mm² conductors. The amplifier also furnishes 1 A of brake supply for holding brakes when the axis is stationary.

Total heat generation during rated operation is 45 W, while standby quiescent loss is limited to 15 W; these figures simplify cabinet cooling calculations for continuous duty cycles. Connected load on the upstream DC supply is 1.7 kVA, reflecting steady-state electrical demand. The aluminum housing measures 275 × 71 × 235 mm and weighs only 2.1 kg, allowing high-density mounting on DIN rails or backplates without reinforcement. Field wiring for the 1 A brake output, power bus, and motor phases is consolidated on the front face to keep service access straightforward.
