Delta Tau Geo PMAC


Integrated Controller-Amplifiers

8 Axis Controller

The Geo PMAC Drive is a 1- or 2-axis standalone-capable integrated controller/amplifier (Direct PWM) with a built-in full PMAC2 controller with stored-program capability. It can be operated standalone or commanded from a host computer through USB2.0 or 100 Mbps Ethernet ports. The controller has the full software capabilities of a PMAC (see the Features tab), with an internal fully-digital connection to the advanced Geo power-stage , providing a convenient, compact, and cost-effective installation for one and two-axis systems that can be interfaced with other drives and controls.

Choices for main feedback for each axis include Digital A Quad B encoder, sinusoidal encoder, EnDat 2.2, HiperFace, SSI encoder, or resolver. It also has:

  • a secondary A/B quadrature encoder for each axis.
  • General-purpose isolated digital I/O: 8 in, 6 out at 24VDC.
  • 2 optional A/D converters at 12- or 16-bit resolution.
