Product Introduction
The Danaher Motion S30301-NA SERVOSTAR 343 is a three-phase, high-voltage-class servo amplifier for industrial positioning and motion-control applications. It accepts a 208–480 VAC supply and provides closed-loop motor control through compatible feedback devices. Its current rating varies with the supply voltage, so motor selection must use the applicable voltage-specific output rating rather than treating the drive as a constant 3 A device.
S30301-NA S300 DANANER
The S300 platform integrates analog setpoint inputs, CANopen communication, an RS232 commissioning interface, and programmable motion-control functions. The S30301-NA configuration has no built-in fieldbus expansion card, but CANopen is available onboard. Its STO safety function provides a means of preventing motor torque when correctly integrated into a suitable machine safety circuit.
Major Features and Advantages
Three-phase high-voltage operation
The SERVOSTAR 343 supports a broad 208–480 VAC supply range. This makes it suitable for industrial servo installations using different three-phase supply levels, provided the motor and drive ratings are matched correctly.
Voltage-dependent current capability
The output-current rating changes with input voltage. The documented values are 5 A RMS at 208–230 VAC, 4 A RMS at 400 VAC, and 3 A RMS at 480 VAC. Peak output current reaches 7.5 A RMS for approximately five seconds.
Integrated CANopen communication
The onboard CANopen interface uses the DS301 communication profile and DS402 drive profile. It supports motion-related commands, homing, jogging, and setpoint transmission. The default CAN baud rate is 500 kbaud.

Analog command inputs
Two onboard analog inputs support ±10 V signals. These inputs provide an alternative command interface for compatible motion-control architectures.
STO safety function
The S30301-NA includes the STO option. The safety function must be wired and evaluated within the complete machine safety architecture; the presence of STO alone does not establish the safety rating of the machine.
PC-based commissioning
The RS232 interface supports parameter configuration and drive diagnostics through compatible setup software. The front-panel keys and three-character display also provide basic local operation and status indication.
Application Scenarios and Field Pitfalls
Typical applications include:
- Industrial machine-axis positioning.
- Packaging and material-handling machinery.
- Automated assembly equipment.
- CNC auxiliary servo axes.
- Precision positioning and synchronized motion systems.
- Industrial machinery using CANopen motion control.
Important replacement checks:
- Confirm the complete
S30301-NAdesignation. - Verify the three-phase supply voltage and available power.
- Match the motor’s continuous and peak current requirements.
- Confirm encoder or resolver feedback compatibility.
- Check CANopen node configuration, baud rate, and drive parameters.
- Verify STO wiring and machine safety integration.
- Check the motor brake, regenerative braking circuit, and external resistor requirements.
- Confirm firmware and hardware revision before transferring parameter files.
A critical distinction: S30301-NA is the SERVOSTAR 343, not the SERVOSTAR 303. The latter uses model number S30361-NA and belongs to the 110–230 VAC voltage class. These drives are not direct electrical substitutes.

The expansion and device-option suffixes indicate different hardware configurations. Verify the complete ordering code before selecting a replacement.
Procurement and Quality Control
For a replacement , request:
- Complete nameplate and serial-number photographs.
- Hardware and firmware revision information.
- Inspection of power-stage terminals and DC bus connections.
- Evidence of successful power-up and diagnostic testing.
- CANopen and RS232 communication test results.
- Motor feedback and enable-circuit verification.
- STO functional test documentation.
Procurement recommendation: Specify Danaher Motion , SERVOSTAR 343, 208–480 VAC, with onboard CANopen and STO. Do not substitute an S30361-NA based only on the shared S300 family designation.
