Posys Motion Control GmbH & Co.KG

PCI-Bus motion controllers

It is a state-of-the-art 1 to 4 axes PCI-Bus motion controller supporting multiple host connection modes and motor types. The POSYS® 1900 supports parallel-bus via PCI-Bus, serial communication (RS232) and CAN 2.0B. Motor types supported are DC brushed servo, brushless servo (internal and external commutation), micro stepping and stepper motors, and each axis individually configurable. Other features are the fast servo loop update rates of 51, 2 µs/1 axes to 256 µsec/4 axes, 8 Mcounts/sec quadrature encoder input and on-board trace capabilities. Additionally the software was enhanced to support circular interpolation and G-Code commands.

A special feature only available on POSYS Motion Controls POSYS® 1800/1900 controllers is the ability to define additional PID parameters which become active under user-configurable circumstances. The main point is to allow the controller to activate an additional set of parameters at any time without interaction by the host or host software to compensate jerk, heavy load accelerating or stiction (as on Piezo motors) and partially varying system friction due to high tolerances within the mechanics.
