Product Description:

The ATS-SERVOSTAR 603-AS-BV is a digital servo drive manufactured by Kollmorgen for the S600 Servo Drives series. It converts fixed AC mains power into controlled motor power and manages feedback so that connected axes reach commanded speeds or positions with high precision. By integrating current regulation, fieldbus communication, and protective switching, the unit occupies a central role in industrial automation cells that rely on compact, cabinet-mounted motion controllers.

Input safety circuitry is energized by a 24 VDC relay, and the associated BTB/RTO path can conduct 500 mA to support emergency-stop logic. The drive supplies a continuous phase current of 3 A rms while delivering up to 6 A rms for brief acceleration events; these current levels support machines with an installed load rated at 2 kVA. An output current form factor of 1.01 indicates very low ripple content, which reduces motor heating. Power devices are modulated by an 8 kHz output-stage clock, helping to keep acoustic noise outside most mechanical resonance bands. Internally, the common-mode voltage is limited to 10 V to protect encoders. The analog reference inputs have an impedance of 20 kΩ to AGND, minimizing the load placed on external controllers.

Regenerated energy is managed by an external brake resistor rated at 33 Ω and an internal resistor rated at 66 Ω, preventing excessive DC-bus voltage during deceleration. When operating at the rated load, the housing releases 40 W of heat, while standby dissipation is 15 W; these values establish the enclosure cooling requirements. The drive supports motors with inductance values ranging from 12 mH to 75 mH, enabling operation with a range of midsize iron-core or slotless servomotors. During switching events, the residual voltage drop across the output stage is limited to 5 V, allowing nearly the full bus voltage to reach the motor terminals for dynamic torque production.
