Control Through Industrial Network/Fieldbus Connectivity

The Power UMAC a motion computer with the latest hardware and software technology, providing the most high-performance, flexible machine controller in the world. The Power PMAC is a general-purpose embedded computer. It runs under a hard real-time Linux OS with a sophisticated motion and machine control application built in.

With the capability for a full operator interface, the Power PMAC eliminates the need for a separate PC. Users can also program in the easy-to-use Script language or the standard C language, leveraging its sophistication and flexibility.

Power PMAC Overview pdf

Dynamic Multi-Block Lookahead

Evaluates planned trajectory against motor limits
Slows just enough to stay within position, velocity, acceleration limits
Executes fastest possible traversal within machine constraints

Forward and Inverse Kinematics

Simplifies programming for non- Cartesian mechanisms
User routines convert between tool tip and actuator mechanisms
Permits direct specification of tool tip path

S-curve Acceleration

Automatically limits rate of change of acceleration (jerk)
Specified by jerk magnitude or S-curve time
Provides smooth profiles with reduced high-frequency content

Position Capture and Compare

Specialised circuitry tying encoder counts to I/O
I/O on exact count (w/sub-count interpolation) at any speed
For probing, registration, measurement trigger, laser firing

Gantry Control with Skew Correction

Multiple motors automatically slave commanded trajectory
Automatic removal of power-on skew in homing search sequence
Optional cross-coupling servo correction

Electronic Gearing and Cams

Powerful master/slave techniques
Position following (gearing) requires no program for motion
External time base (cam) keeps full trajectory flexibility

Multiple Coordinate Systems

Axes acting together should be in same Coordinate System
Axes acting independently should be in separate Coordinate Systems
Separate Coordinate Systems act as independent machines

Blended and Splined Moves

Automatic on-the-fly transition for multiple programmed moves
Controlled, specified, acceleration of transitions
For single-axis profiles or multi-axis paths

Power UMAC 465 CPU

CONTROL EVERYTHING:

Delta Tau’s Open Architecture Platform provides complete flexibility to choose multiple types of motors, feedback devices, encoders and fieldbuses so you can create a system perfect for your application.

Additional axes, feedback, I/O and/or fieldbus interfacing is obtained by sliding accessory cards into the 3U rack system, available in 3 choices of rack widths (largest 21-slot version pictured below).
