POSYS® 700 Series
The POSYS® 700 (Designed & Made in Germany) is a state-of-the-art 1 to 4 axes ISA-Bus motion controller supporting multiple motor types. The POSYS® 700 supports parallel- bus via ISA-Bus communication. Motor types supported are DC brushed servo, brushless servo w/ external commutation, microstepping w/ microstepping drives and stepper motors. Other features are the fast servo loop update rates of 100 µs/1 axis to 400µsec/4 axes, 5 Mcounts/sec quadrature encoder input and on-board trace capabilities.
Highlights
Motion profiles include S-curve, trapezoidal (with smoothing factor), velocity contouring, and electronic gearing, linear interpolation for 4 axes. In addition they also support external profile mode which allows the user to download complex motion profiles directly in to the controllers memory relieving the host from extensive calculation tasks.
With up to 164 commands, depending on model, the POSYS® instruction set offers flexibility and versatility to software application programmers. Instructions are used to initialize and control the motion processor. User selectable profiling modes supported by the motion processor include S-curve, trapezoidal, velocity contouring and electronic gearing. The POSYS® 7xx accepts input parameters such as position, velocity, and acceleration from the host and generates a corresponding trajectory within 12.5 µs.

| Profile modes | S-curve point-to-point ramp (velocity, acceleration/deceleration, Smoothing and position parameters); change of parameters "on-the-fly" not possible in this mode Trapezoidal point-to-point ramp (velocity, acceleration/deceleration, position and PID parameters); all parameters "on-the-fly" changeable during motion Electronic Gear (actual or commanded positioning selectable to move one or more axes with upto ±16 bit resolution. Master and Slave Axes and Gear Ratio parameters) External Profile Mode allows the usage of profile data previously generated by the host computer to be saved in the controller's memory. Therefore low host intervention for highly complex profile movements. This memory can be used in parallel for gathering data for diagnostic, maintenance and to optimize performance.
