The SERVOSTAR-406A-S from Kollmorgen belongs to the renowned S400 Servo Drives series, delivering industry-leading precision in servo amplification. This servo amplifier offers configurable external current limit functionality and reduced-sensitivity input for setting-up/jog operation, simplifying commissioning and manual trials. Designed for high-precision control, it supports a differential input voltage max. of ~10 V and a 12-bit, scalable resolution for fine torque adjustments. The unit features a robust characteristic impedance of 100–120 Ω and tolerates a cable capacitance of max. 60 nF/km, ensuring signal integrity over long distances. With lead loop resistance of 159.8 Ω/km and encoder emulation built in, the SERVOSTAR-406A-S delivers exceptional motion fidelity and rapid response.

Technical capabilities of this amplifier include a pre-control/override mode that accelerates torque setpoint changes without sacrificing stability. It complies with standard setting: torque setpoint protocols for seamless integration into existing motion profiles. The device’s interface supports one free serial port (COM1…COM10) for parameterization and diagnostics via a familiar RS232 link. Graphical feedback is handled through any Windows-compatible, color graphics adapter, while firmware updates and parameter storage require only a hard disk with at least 10 MB free space and CD-ROM drive. These features combine to deliver a highly adaptable amplifier core that meets stringent industrial demands.

Operational features emphasize reliability and ease of use. The SERVOSTAR-406A-S employs an insulated auxiliary supply that meets EN 50178 isolation standards and ensures clean 24 VDC power with internal fusing. Safety is reinforced by built-in overvoltage detection, short-circuit protection, and phase-failure control, reducing downtime and protecting connected drives. Temperature monitoring inputs accommodate compatible motor temperature sensors to prevent thermal overload conditions. Maintenance is streamlined through remote parameter adjustments and on-the-fly firmware upgrades, minimizing machine stoppage and improving throughput.

Integration into automation architectures is straightforward: the amplifier’s RS232-based interface enables interoperability with a wide range of PLCs and motion controllers. Support for legacy and modern systems is assured by compatibility with Windows 2000/XP operating environments and a minimum Pentium II or comparable processor for the programming workstation. Encapsulated in a compact housing, the SERVOSTAR-406A-S fits existing drive racks and panel layouts with minimal modifications. Its versatility makes it ideal for packaging, robotics, CNC machining, and other high-precision servo applications.

Testimonials

We used Servo Supplier to refurbish old drives and buy reconditioned parts. We received great and timely service at a fair price. I recommend them to anyone who has aging equipment and can't find support from their OEMs. Highly recommend.

Bostik Inc.

WE absolutely LOVE Servo Supplier. They are quick, efficient and friendly. Honest too, which is huge in our industry. We deal with many different companies, and these guys are tops in our humble opinion. There has never been an issue with delivery, no warranties, no hidden fees, no surprises. Just what you want in the manufacturing business. Smooth, and we love smooth.

Technomech Inc

First-time customer. The ordering process was completely seamless. The part that we ordered was at our business within 2 days. Which was excellent! We had a piece of equipment down for a little more than 48 hours. Could have been a lot longer had we purchased from one of our normal suppliers.

Steve T. from NF&M International

I found these guys online and needed a somewhat obscure part quickly, and they delivered! Very quick process from the time I requested a quote to the shipping of my items. Great work Servo Supplier team!

FlexPac

Servo Supplier is my go to place for obsolete parts. They always seem to find them and the price is usually good. Any time I have questions they respond very quickly and professionally. I highly recommend them!

Middlesex General Industries

They were very quick to get the drive we needed shipped out to us. They were also very quick to respond and help with some pictures of information on the unit we ordered to ensure we received the right part.

Justin Ball from Miba

Understood our situation, and worked to help us get it solved. Very responsive, and stepped out to keep me informed until the product arrived. Exactly as described, and promised.

Brian Tomlin

This company was fantastic to work with! Very patient with us to make sure we were getting what we needed and extremely quick shipping. Would definitely purchase from them again and again!

Carla Morgan

We asked for a fast turn around and Wake was up to the task!
