Product Description:

The S403BA-CA is an axis-level servo drive manufactured by Kollmorgen as part of the S400 Servo Drives series. Intended for industrial automation, this module regulates current and velocity for a single motor and interfaces directly with a host controller through an analog command channel. By converting control signals into three-phase output power, it forms the core of a compact motion axis, eliminating the need for discrete amplifiers or external feedback conditioning.

On the command side, the drive presents an input impedance of 20 kΩ and resolves the ±10 V reference with a 14-bit converter. The signal is refreshed every 62.5 µs, allowing tight loop gains when the axis module is paired with high-bandwidth controllers. The ±10 V window, centered at zero, provides symmetric torque commands and is highlighted here as a ±10 V analog range. The power stage supplies up to 9 A rms for acceleration while sustaining 3 A rms continuously; both figures assume an external DC link because the unit is specified with no integrated supply. Quiescent dissipation is 12 W, and another 30 W is produced at rated output, all removed by free convection through the heatsink fins.

Mechanically, the housing measures 50 mm across the front, 240 mm from front to back, and 230 mm in height, allowing dense stacking inside a cabinet that is ventilated by natural convection. Enclosure protection is rated at IP20, so parts are guarded against touch but the module must reside in a closed panel. Installation weight is 1.7 kg, reducing strain on DIN-rail or plate mounts and simplifying handling during installation. The drive conforms to vibration class 3M1 for industrial machinery and maintains an acoustic emission of 45 dB(A), keeping sound levels low around assembly stations. The module fits standard control cabinets and does not require active cooling or special shock isolation.
