Introduction
loop operation. Interface to the direct-PWM amplifier is through a standard 36-pin Mini-D style
cable. The drive performs no control functions but has protection features. Drive installation,
maintenance, and replacement are simplified because there is less wiring (position feedback and I/O
are not connected to the drive) and there are no variables to set or programs to install in the drive.

•
Fully centralized control means that all gains and settings are made in the PMAC; no software
setup of drive is required

•
No position feedback or axis flags required at the drive
Geo PMAC Drives
The Geo PMAC Drive is a standalone-capable integrated controller/amplifier with a built-in full
PMAC2 controller having 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 descriptions), 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, with easy synchronization to other drives and controls.
