Power UMAC

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.

Product features

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

Electronic Gearing and Cams

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

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

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

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).
