KOLLMORGEN S200 High Performance Compact Brushless Servo Drive

Introduction: Redefining Compact Servo Performance

In the field of industrial automation, the performance, volume, and reliability requirements for servo drives are becoming increasingly stringent. The S200 series high-performance compact brushless servo drive launched by Danaher Motion (now under Kollmorgen) is designed to address this challenge. This series of drivers integrates industry-leading servo technology into a full power range product family, covering both DC and AC input models, particularly in low-power applications, providing unprecedented high-performance, high robustness options without compromising on reliability or packaging size.

The S200 driver represents a significant advancement in fully digital industrial drive technology, with a speed bandwidth of up to 80 Hz. Combined with high-resolution (24 bit) feedback and a current bandwidth of up to 3-5 kHz, it achieves smooth motion control and fast start stop response, significantly optimizing machine performance. Its "intelligent feedback" technology combined with industry-leading high bandwidth eliminates the need for servo loop debugging in most applications, achieving fast and accurate "plug and play" debugging.

Product Overview and Core Features

The S200 series drivers are designed for demanding applications such as semiconductor manufacturing, electronic assembly, packaging, medical and woodworking equipment. Paired with Danaher Motion's AKM series servo motors, it can form a complete servo control solution.

The core features include:

Control Logic: Version 3.0 or higher. Units produced after November 2007 fully comply with the EU RoHS directive.

Standard control mode: The basic unit comes standard with torque or speed control.

Scalability: The factory can optionally add tabs that support SynqNet motion networks, or add preset indexes with CANopen communication.

Wide feedback compatibility: The tab has added interfaces with additional motor feedback devices such as Comcoder, 1 Vpp Sin Cos, EnDat 2.1, and EnDat 2.2 running in 2.1 compatibility mode, supporting single/multi turn absolute rotation or incremental/absolute linear encoders.

Flexible power input: Supports AC (120/240 VAC) or DC (20-90 VDC) power supply, with current ratings ranging from 1.5 ARMS continuous to 48 ARMS peak.

Compact design: Width ranging from 1.1 inches (28.7 millimeters) to 3.8 inches (94.6 millimeters), height ranging from 6.0 inches (152.4 millimeters) to 8.39 inches (213 millimeters), depth ranging from 3.9 inches (100.8 millimeters) to 7.57 inches (192.4 millimeters), suitable for space constrained applications.

Independent 'keep active' control power supply: allows communication and diagnosis to be maintained in case of emergency stop due to motor power failure, and can be quickly restored.

Security: Optical isolation input/output, forward locking connectors, and comprehensive fault protection, promising long machine life and resistance to accidental damage.

Detailed technical specification analysis

3.1 Drive family power

The S200 series offers multiple models to meet different power requirements. Taking the 240VAC input model as an example, its peak output current range ranges from 4.5 ARMS in S20260 to 48 ARMS in S22460. The continuous output power ranges from 600W in S20260 to 8000W in S22460 at 240VAC three-phase. For DC input models (such as S20330/S20630), the continuous output power is 250W and 500W respectively at 75VDC bus voltage. All specifications are effective within the specified ambient temperature (0-50 ° C) and line voltage range, and the derating curve needs to be considered.

3.2 AC Input Driver - Control and Power Supply

Control power supply: Input voltage range up to 85-265 VAC single-phase (47-63 Hz) or 120-375 VDC. Has the ability to temporarily maintain line voltage, for example, it can maintain over 18.5 cycles at 240VAC/60Hz.

Motor power supply: S20260/360/660 supports 0-265 VAC, S21260/22460 supports 120-265 VAC, compatible with single-phase or three-phase input. It is recommended to configure isolation transformers with corresponding capacity to limit power grid surges.

Bus voltage and faults: The nominal bus voltage is 320VDC when input at 240VAC, and 155VDC when input at 120VAC. The bus overvoltage fault point is set to 407VDC ± 5%.

Surge current and fuse: The manual provides detailed peak surge current data and recommended delay fuse models for different models, phases, and voltages (such as Bussmann FRN or JKS series).

3.3 DC Input Driver - Control and Power Supply

Control power supply: Voltage range+10 to+90 VDC, recommended to use a minimum 20W power supply to ensure reliable startup.

Bus voltage and faults: operating range+20 to+90 VDC, undervoltage fault approximately+17VDC, overvoltage fault approximately+91VDC.

3.4 Motor current control

Current loop bandwidth: AC input driver maximum is 3 kHz (recommended 2 kHz), DC input driver maximum is 5 kHz (recommended 3 kHz). The intelligent feedback device automatically sets the bandwidth to 2 kHz.

Offset current: varies with model and temperature, with a typical value of 0.2% of full scale and a worst-case (over temperature) value of 0.5%.
