Product Description:

The DSA 014-460 is a servo drive module produced by Kollmorgen within the DSA SERCOS Drives series. It converts three-phase utility power to a controlled, high-bandwidth output that energizes synchronous servo motors while communicating motion profiles over the SERCOS interface. In automated cells, the drive handles both power conversion and real-time axis regulation for coordinated speed, torque, and position control. Its closed-loop architecture allows the controller to correct speed and position deviations quickly as load conditions change.

The drive supplies a continuous phase current of 7 A, allowing motors to maintain rated torque during prolonged cycles, and it can deliver 14 A for short bursts required by rapid accelerations. During deceleration, its internal snubber absorbs up to 219 Joules of regenerated energy before external circuitry is engaged. An external braking resistor may be connected, and the unit can dissipate 3 kW of heat through that path on a continuous basis, helping control DC bus voltage during cyclic duties. Digital control loops stay responsive because the discrete I/O channels propagate state changes within 100 µsec. On the line side, the converter draws approximately 4 Arms under nominal load, which helps with branch protection and conductor sizing in the control cabinet.

The unit operates without derating up to 1500 m above sea level, supporting most plant elevations. Its command inputs can accept differential TTL edge rates as high as 2.5 MHz, enabling high-resolution encoder capture or pulse-train velocity references. Cabinet layout benefits from the modest mass of 8.55 kg, which simplifies mounting and reduces vibration loading on enclosures. The main inrush current is 6 Arms, the minimum braking resistor is 120 Ohms, and the internal shunt capability is 100 W, giving clear electrical limits for system integration during high-load operation.
