Product Description:
The SERVOSTAR-403A-P is a servo drive produced by Kollmorgen within the S400 Servo Drives series. It is designed to regulate torque, speed, and position of synchronous or induction motors in automated machinery. The drive serves as the interface between the motion controller and the motor, converting command values into controlled electrical output for repeatable axis movement. It is suited to applications such as indexing tables, packaging equipment, and feed axes where quick response to changing load conditions is required.
The power section accepts a mains supply of 230 to 400 V and delivers a continuous phase current of 3 A rms, while short-term demand can rise to 9 A rms. Logic and sensor circuits use a separate 24 V DC supply, and the output stage switches at 8 kHz for controlled motor current. A current form factor of 1.01 shows that the output waveform remains close to a sine wave, which helps limit extra heating in the motor windings. Stable current regulation requires motor inductance between 12 mH and 75 mH, and a built-in 33 Ω brake resistor absorbs regenerated energy during deceleration. Thermal losses include 12 W of quiescent dissipation plus an additional 30 W at rated current, and the drive is intended for cabinet installation in Pollution Level 2 conditions.
With a width of 50 mm, a depth of 240 mm, and a height of 230 mm, the unit occupies limited panel space and weighs 1.7 kg. The enclosure is rated IP20, so it is intended for touch-safe installation inside a closed cabinet rather than open exposure on the machine. Because cooling relies on cabinet airflow rather than an external heat sink, adequate ventilation is needed around the unit during full-load operation. The narrow profile also helps when several axes are mounted side by side in the same control cabinet.
