AMC FlexPro Servo Drive in a Robot HandThe FlexPro® drive series is our latest family of digital servo drives designed for high power, small size, and the best available servo motor control.

The IMPACT™ architecture of FlexPro® allows for higher power densities while still maintaining the reliability and versatility of our established drive families. In addition, the advanced processing and storage capabilities ensure that drives with IMPACT™ are more intelligent and operationally flexible than ever before.

FlexPro® drives are designed to operate within a network, but like previous digital drives, they can also operate stand-alone via stored indexes and sequences with I/O. They’re capable of brushed, brushless, stepper, and linear motor control.  The FlexPro® family continues to grow, with more products on the way. Future models will include more network options, and greater power ranges.


The FlexPro® servo drive family has two main subgroups: the Micro-Size versions and the Mini-Size. While both are very compact and boast the same features and technology, the differences in size and power range merit the separate classifications.

As the names might imply, the micro-sized FlexPro drives are the smaller of the two. The base units have a footprint of 1.50 x 1.00 inches (38.1 x 25.4 mm). The input voltage ranges for these are 10-55 VDC or 20-90 VDC, with both peak and continuous current ratings as high as 60 amps.

The slightly larger mini-sized versions are slightly less compact, but they have higher power capabilities. They have a footprint of 1.70 x 1.50 inches (43.2 x 38.1 mm). The input voltage range for these is 20-90 VDC, with a continuous current rating of 50 amps and a peak currents rating of 100 amps.

Micro vs Mini

Form Factors

FlexPro® drives can fit into tight spaces and still deliver the impressive power and performance to your robot joints, AGV traction wheels, or any other application. ADVANCED Motion Controls® offers various form factors of FlexPro® drives for each power level to ensure that it can be used anywhere.

PCB Mount

The FE servo drives are the standard FlexPro base-units. These drives are PCB mount-style, so they’re designed to be integrated directly into your PCB interface in single- or multi-axis configurations. Their small form factor also makes directly integrated servo motor and drive solutions possible.

Don’t underestimate these drives for their size; great things come in small packages. The FE060-25-EM, for example, runs on 10-55 volts DC, communicates over EtherCAT, supports incremental encoder and BISS C-Mode feedback, delivers peak and continuous currents of 50 amps and 25 amps respectively, and has a maximum power dissipation of just 14 watts.

Machine Embedded

For those seeking to install drives beyond the central PCB, the FM machine embedded servo drives feature convenient connectors that make them easy to hook up to any system using standard cabling. The drives can also be configured easily via a USB-C connector.

Our 5-amp and 10-amp continuous versions feature Phoenix connectors for the motor and DC voltage connections while the 25-amp and 45-amp continuous versions features flying leads.

Panel Mount

Panel mount is the traditional form factor for servo drives. The panel mount FlexPro drives feature the same drive as they PCB mount version in a larger protected shell with a built-in logic power supply and large connectors. This serves well for engineers who would like to use the technology of FlexPro in more protected form and traditional mounting option.

Development Board

If you’re in the development phase of your project, the FD drives feature a development board with various connection options, allowing for quick and easy configuration and setup.

With full-size communication ports, feedback connectors, and power terminals, the FD drives allow you to prove your concept before integrating FlexPro™ drives into your system.

Extended Environment

New CANopen Extended Environment FlexPro Drives!

Extended Environment versions of both the PCB mount and machine embedded FlexPro drives are also available. They offer all the convenience and power of the standard FlexPro drives, but they're built to handle more extreme environmental conditions.

These drives can operate in temperatures as low as -40°C to as high as +95°C (-40°F to +203°F), and their thermal shock resistance allows them to go from one end of that range to the other in just three minutes without any damage.

They can also withstand 95% non-condensing humidity, pollution degree 2, and vibration in 3 axes for up to five minutes at 25 G (rms).

When it comes to altitude, the sky is quite literally the limit, as they can operate as high as 25,000 m above sea level.
