Product Description:

The SERVOSTAR-620-AS-FAN is a servo drive produced by Kollmorgen within the S600 Servo Drives series. In an automation cell it regulates current and voltage to permanent-magnet servo motors, enabling precise speed and position control for material handling, packaging, and processing machinery. By converting three-phase supply power into controlled pulses, the unit forms the link between a motion controller and the motor, integrating motor-feedback data and safety relay functions to maintain deterministic motion profiles.

The housing carries an enclosure rating of IP20, so the drive must be installed inside a control cabinet that shields it from dust and direct contact. A continuous output current of 20 A rms supports typical production loads, while a short-term peak of 40 A rms for two seconds covers acceleration or shock demands. Thermal management planning must consider a dissipation of 200 W at rated current; this loss is separate from the series’ integral fan that turns on when the heat-sink reaches 65 °C. The incoming supply should be sized for a rated installed load of 14 kVA, ensuring cable and circuit-breaker compatibility during sustained high-duty cycles.

An output current form factor of 1.01 shows the drive’s nearly sinusoidal output, minimizing additional motor heating. Motor selection must stay between a minimum inductance of 2 mH and a maximum of 12 mH to keep current control loops stable. Acoustic emission does not exceed 45 dB(A), which helps maintain a low-noise electrical cabinet. Two analog monitor outputs provide real-time access to internal variables such as torque command or bus voltage. The safety relay operates from a 24 VDC source, and a residual voltage drop of 5 V across the output stage must be included when calculating motor terminal voltage. Quiescent dissipation remains 15 W with the motor idle, and an input resistance of 20 kΩ to analog ground protects upstream signal generators from excessive loading.
