PMAC-Pack/Expansion Pack Re-assembly
After connecting the cables inside the PMAC-Pack, perform steps 1 through 4 to reassemble the PMAC-
Pack and Expansion Pack (see Figure 8-3).
STEP #1 -
Rotate the PMAC-Lite card on its hinges until it is flush against the case standoffs. Insert the
three mounting screws to secure PMAC-Lite to the case. Check that all internal connections are secure.
STEP #2 -
Fold the left half of the PMAC-Pack casing into the right. First insert the rear lip of the left
half into the back of the case. Rotate the left half of the case until it is flush with the right. You may need
to pull the left halve slightly forward to clear the front right lip.
STEP #3 -
Insert eight sheet-metal screws as shown to secure the left and right halves of the casing
together. Leave the top and bottom screws on the right side of the PMAC-Pack loose.
STEP #4 -
Slide the PMAC-Pack and Expansion Pack together, insuring the slots in the top and bottom
brackets on the Expansion Pack slide under the PMAC-Pack screws. Any excess cable length should be
carefully inserted into the expansion Pack. Tighten the four PMAC-Pack screws.
PMAC-Pack/Expansion Pack Software Setup
The following steps will configure the PMAC-Pack software to activate and utilize Expansion Pack axes
5 through 8. These steps are necessary because the Expansion Pack adds hardware interface channels
(encoders, DACs, and flags) numbered 9 through 12, which must be mapped to motors 5 through 8.
Note:
As of February 1997, all PMAC-Packs are factory configured to use the expansion
pack. This section should be read to gain a clearer understanding of the Expansion
Pack, however, Delta Tau has preconfigured the software to control non-
commutated axes connected to the Expansion pack.
