based computers. Starting with MOTIONEXE.EXE version 10.32.00, which is
included in PEWIN32 version 2.32 and newer, a PMAC2 PCI board plugged in a PCI bus slot will be
recognized by the operating system when the computer is booted up. The available PCI address,
dual-ported RAM address and Interrupt lines are set automatically by the operating system and can be
checked (but not modified) in the MOTIONEXE.EXE application or the resources page of the device
manager.
PMAC I-Variables
PMAC has a large set of Initialization parameters (I-variables) that determine the personality of the
card for a specific application. Many of these are used to configure a motor. Once set up, these
variables may be stored in non-volatile EAROM memory (using the SAVE command) so the card is
always configured properly (PMAC loads the EAROM I-variable values into RAM on power-up).
The easiest way to program, set up and troubleshoot PMAC is by using the PMAC Executive
Program PEWIN and its related add-on packages Turbo Setup and PMAC Plot. These software
packages are available from Delta Tau, ordered through the Acc-9WN accessory.
The programming features and configuration variables for the PMAC PCI are discussed in the Turbo
PMAC User and Software manuals.
