Kollmorgen SERVOSTAR 343 (TM343 / S30301-NA) — SERVOSTAR 300 Series Digital Servo Drive
The Kollmorgen SERVOSTAR 343 (TM343 / S30301-NA) is a compact, mains-fed digital servo amplifier from the SERVOSTAR 300 family, rated approx. 3 A RMS (approx. 9 A peak) at 3×208–480 VAC, 3-phase, 50/60 Hz. It provides precise, low-latency motion control for brushless servo motors with resolver or high-resolution sin/cos encoder feedback — a proven, cost-effective drive for mid-power single-axis applications.
The "-NA" suffix denotes the standard version without option cards. Direct mains operation, RS232 setup and encoder emulation are built in as standard, with parallel DC-link capability for compact multi-axis systems.
Your Benefits at a Glance
- 3 A rated / approx. 9 A peak — solid performance for mid-power servo axes
- Direct mains operation — 3×208–480 VAC, no separate supply needed
- Resolver or high-resolution sin/cos encoder feedback — wide motor compatibility
- Fully programmable via RS232 — quick setup with PC-based software
- Parallel DC-link capability — compact multi-axis systems with shared bus
- Proven SERVOSTAR 300 platform — trusted worldwide in machine automation
Key Features
Standard Version Without Options The "-NA" suffix means no option cards are fitted — the well-proven standard SERVOSTAR 343 configuration with all core functions included.
Flexible Feedback Feedback is supported from resolver or high-resolution sin/cos encoder, covering a broad range of Kollmorgen and third-party brushless servo motors.
Direct Mains Operation Runs directly from 3×208–480 VAC mains (overvoltage category III per EN 61800-5-1), simplifying installation without a separate power supply.
Multi-Axis Ready The DC-link circuits can be connected in parallel, enabling compact, cost-effective multi-axis systems with a shared supply.
