maxon motor has developed a new range of intelligent positioning controllers known as EPOS. Small and compact, they feature the very latest technology and come at an attractive price.
The controllers are currently available in two versions: a midi-version at 24V and 5A continuous current, and a micro-version at 24V ad 1A, which means that highly dynamic precision drives and control systems can now be realized in the minutest dimensions. Several drives can be networked and coordinated through a standardized CANopen interface and the controllers operate in position, speed or current control mode.
The controller is commanded via
the CANopen interface or alternatively via RS232. Electronically or mechanically
commutated motors can be driven. A sinusoidal commutation of current and space
vector modulation (SVM) is being used for brushless EC motors. This not only
improves motor efficiency, but minimizes moment ripple and noise. The algorithms
run on a fast signal processor and built-in chokes ensure smoothness of
operation, even for low-impedance motors. The two EPOS have free digital as well
as analog inputs and digital outputs for connecting peripheral drive equipment,
limit switches etc.
A Windows® based user interface is available for configuring, setting up and autotuning control parameters. It is supplied together with comprehensive operating instructions on a CD. The CD also contains various software examples and libraries for network operation with PC or SPS and CANopen. The operating instructions and software can be downloaded free of charge from maxon's homepage.
