5.2.7 Option Con using Microstepping Cards
(part numbers MB802440, MB802420, MB802410)
The following table shows connections to the Option Con connector when the card type is
microstepping. Unless otherwise noted, 1 indicates axis 1, 2 indicates axis 2, etc., and A indicates phase A,
B indicates phase B, etc. Note that in addition to the Option Con connector detailed below, proper operation of
the microstepping cards also requires connections to the J1 and J7 connectors. See section 5.2.3, J1 and J7 using
Brushless DC Cards, Microstepping Cards and Mixed Motor Cards, page 59, for a detailed list of J1 and J7 connections.
