Kollmorgen SERVOSTAR 300 (S300) series digital servo drive

Product Overview and Model Code

Product Core Positioning

The S300 series is a digital servo drive launched by Kollmorgen for medium power high-precision motion control scenarios. The hardware version has been iterated to 04.20, supporting SFD3/HIPERFACE DSL single cable connection, integrating STO safety function, suitable for synchronous servo motors, asynchronous motors, and linear motors, and can expand bus and I/O capabilities through expansion cards. Its core advantages lie in dual voltage adaptation, multi feedback compatibility, and flexible expansion performance, and it is widely used in automation production lines, precision machine tools, multi axis collaborative equipment and other scenarios.

Installation and wiring specifications

Installation Requirements

Installation method: Vertically installed on a conductive grounding surface, the control cabinet needs good ventilation

Heat dissipation gap: top/bottom ≥ 40mm, side ≥ 75mm, high-power models require the installation of a fan

Mechanical dimensions: width 70mm, height 270-279mm, depth 171mm, weight approximately 2.6-2.7kg

Environmental restrictions: Working temperature 0-40 ℃ (with a capacity reduction of 2.5%/℃ for 40-55 ℃), humidity 10-85% (without condensation), altitude<1000m (with a capacity reduction of 1.5%/100m for 1000-2500m)

Core interface wiring

The manual provides detailed wiring definitions for 17 core interfaces, with the following key points:

Power wiring: X0 interface distinguishes 1/3 phase input, L1/L2/L3 is connected to the main power supply, and PE grounding must comply with IEC 60364 specifications

DC bus wiring: X8 interface supports parallel connection of multiple drivers (total current of 110-230V series ≤ 24A, 208-480V series ≤ 40A), requiring 2.5mm ² shielded cable

Motor wiring: X9 interface connects U/V/W three-phase, brake signal BRAKE+/BRAKE - supports 24VDC/1.5A brake control, motor cable>25m requires motor choke coil

Feedback wiring: X1 supports SFD3/HIPERFACE DSL single cable, X2 supports Resolver, X5 supports SSI/incremental encoder, feedback cable requires twisted pair shielding

STO wiring: X4 interface STO-ENABLE needs to be connected to a 24VDC safety signal. When disconnected, the motor can stop freely due to demagnetization, and mechanical braking needs to be used to ensure the safety of vertical loads

Troubleshooting and Maintenance

Core fault codes and troubleshooting

Fault codes, fault types, common causes, troubleshooting methods

F01 heat sink overheating environment temperature is too high, and the heat dissipation gap is insufficient. Clean the heat dissipation channel, reduce the load, and check the fan (- FN model)

F02 bus overvoltage brake resistor failure, rapid deceleration check brake resistor wiring, extend deceleration time, install external brake resistor

F04 feedback fault feedback cable breakage, wiring error check feedback wiring, measure feedback power supply, replace cable

F06 motor overheating, motor overload, thermal sensor failure to reduce load, check motor thermal sensor wiring, measure winding temperature

F27 STO fault: Both STO-ENABLE and ENABLE effectively adjust the control logic to ensure that the motor has stopped before STO activation

Key points of daily maintenance

Regular inspection: cleaning of heat dissipation channels, fastening of wiring terminals, integrity of feedback cable shielding, recommended every 6 months

Capacitor reformation: When stored for more than 1 year without use, 230VAC single-phase electricity needs to be added for 30 minutes to activate the capacitor

Parameter backup: Backup parameters (. cfg files) through DRIVE GUI software to avoid configuration loss due to misoperation

Expansion card maintenance: When inserting or removing expansion cards, power must be turned off. During installation, ensure that the guide rail is inserted into place and the screws are tightened
