Kollmorgen S20360-VTS-021 Servo Drive

Introduction

The Kollmorgen S20360-VTS-021 is an all-digital, compact industrial servo drive from Kollmorgen’s high-performance S200 series. Engineered to deliver high-bandwidth control for brushless servo systems, this single-axis drive was pioneering as one of the first all-digital industrial drives to achieve a velocity loop bandwidth of 800 Hz.

Configured for versatile base unit operation, it focuses primarily on velocity and torque control modes driven by precise analog command signals. The drive converts line power into highly regulated three-phase outputs, making it a reliable solution for fast-cycling, high-throughput automation setups where sub-millisecond loop updates are critical to keeping positioning errors near zero.

Technical Parameter Table

Unique Product Description

The Kollmorgen S20360-VTS-021 sets an impressive standard for power density, packing a 3A continuous and 9A peak output into a narrow, book-style chassis that stands just 175 mm high. Its primary distinction lies in its smart integration with Kollmorgen’s Smart Feedback Device (SFD) technology. When paired with an SFD-equipped motor, the drive utilizes an 18-bit analog reference input and a native 24-bit feedback converter to achieve plug-and-play commissioning.

The drive reads electronic motor nameplates instantly, completely eliminating manual parameter configurations and loop tuning. Additionally, its separate “Keep Alive” control logic power input preserves status monitoring and allows for rapid system recovery following an emergency stop condition.

Product Advantages and Features

Advanced Control Bandwidths: Features an exceptional 3 kHz current loop and an 800 Hz velocity loop to ensure rapid, crisp motor responses under fluctuating loads.

Plug-and-Play Commissioning: Built-in compatibility with electronic motor nameplates minimizes initial engineering setup and hardware matching errors.

Flexible Power Grid Handling: Operates seamlessly on either single-phase or three-phase power grids (120V/240VAC) without requiring specialized step-down transformers.

Full Transient Protection: Built with optically isolated inputs/outputs, positive locking wiring connectors, and short-circuit fault protection to shield the drive from electrical interference.

Compact, Side-by-Side Mounting: The ultra-narrow 54.8 mm width permits high-density, side-by-side backpanel arrays, dramatically decreasing required control cabinet real estate.

Application Cases

High-Speed Pick-and-Place: Ideal for Cartesian or delta sorting systems requiring lightning-fast acceleration and minimal settling times.

Packaging and Form-Fill-Seal Machinery: Controls continuous labeling, film wrapping, and rotary knife axes where timing tolerances are razor-thin.

Electronic Component Assembly: Manages delicate semiconductor positioning loops that rely on exceptionally smooth torque delivery at low speeds to prevent component damage.

Automated Conveyor Indexing: Operates transfer lines that undergo rapid start-stop duty cycles with variable mechanical payloads.

Installation and Maintenance

Installation Guidelines

Vertical Orientation: Mount the drive vertically on a flat, unpainted, grounded conductive metal panel inside an enclosure rated IP54 or better to avoid airborne contaminants.

Clearance Envelopes: Ensure a minimum clearance above and below the drive chassis to facilitate proper convection cooling. Do not block the integrated air ventilation paths.

Command Grounding: Wire the $\pm 12.5\text{ V}$ analog command signal using twisted-pair, shielded cables. Ground the shield at the controller side to protect the input reference line from high-frequency electromagnetic noise.

Maintenance Actions

Cabinet Environment Cleaning: Periodically vacuum or clear out debris from the control panel to prevent dust insulation on the drive’s aluminum heat sink fins.

Screw Terminal Integrity: Inspect plug-in screw terminals and positive locking feedback connectors regularly to verify they remain tight and free from vibration displacement.

Capacitor Discharge Window: High voltage remains present on the internal DC bus long after line power is disconnected. Always wait at least 5 minutes and verify that the voltage has dropped to safe thresholds ($< 60\text{ V}$) before servicing wiring or removing terminals.
