Product overview
AM controller
The AM is the lightest standard member of the ESC3 controller family. It can be used in a wide range of applications, especially in industrial and automotive. Using the most modern technologies, it achieves extreme dynamics and maximal efficiency. It implements smooth start and regenerative braking, all within minimum dimensions. The AM controller is capable of driving all common types of electric motors.
Controller editions (housing variants)
AM controller may come in different housing variants, called editions. Each edition provides different levels of protection and thermal management. The following editions of the AM controller exist:
- Sealed Al housing. Aluminium enclosure, waterproof (sealed). Best protection and thermal conductivity.
- Non-sealed Al housing. Aluminium enclosure, open (not sealed). Good thermal conductivity.
- Shrinking tube. PCB wrapped in shrinking tube. Lightweight, basic protection.
- Bare board. Bare PCB with electrolytic capacitors, without any wiring or enclosure.
- Sealed Al housing
- Non-sealed Al housing
- Shrinking tube
- Bare board
This edition is only offered as part of OEM solution and no longer publicly supported.

Product variants
The AM controller is a very versatile product. To match all specific requirements, multiple properties can be adjusted, so many variants exist. Different variants are denoted by different MPN (Manufacturer Part Number).
The MPN consists of several parts:
- Base name -- denotes compatible firmwares (e.g. AM-felix, AM-raptor, AM-serpent)
- Assembly code -- defines voltage/current rating, communication interfaces, motor sensors, and internal HW configuration
- Finish variant -- defines signal/power wiring, housing, and enclosure

Built-in LED status indicator
The AM controller has a built-in LED which indicates the state of the control program:
- Bootloader -- LED lights very briefly while firmware version and checksums are checked. If the controller remains in this state for more than a few seconds, there is a firmware problem. Try updating the firmware.
- Main program -- LED is lit while the Driver initializes.
- Driver -- the motor control part of the firmware:
- LED off -- Driver successfully initialized, motor can be driven
- LED on solid -- Driver status word is non-zero, a high priority limiter may be active. LED turns off after 2 second timeout when condition passes.
- LED blinking -- an error occurred. LED blinks 16 times, pauses, then repeats. Each blink represents one bit of the error word (long blink = 1, short blink = 0, LSB first).
