Motor and controller info

The names, descriptions, and step sizes for the beamline motors are given in Table 4.1, while their connections with controllers and drivers are shown in Table 4.2. Both of these tables are in Chap. 4. Pinouts on the MDU-8 motor drivers are shown in Tables C.1 and C.2.

Table C.1: MDU-8 J1 connector pinouts. The connector is a 22 pin connector with 0.156'' spacing. The J2 connector has the same pinouts as J1, but it is used to supply return pulses as pseudo-encoder inputs.

Pin	Description	Pin	Description
1	Logic ground	2	Logic ground
3	M0 direction input	4	M0 step input
5	M1 direction input	6	M1 step input
7	M2 direction input	8	M2 step input
9	M3 direction input	10	M3 step input
11	M4 direction input	12	M4 step input
13	M5 direction input	14	M5 step input
15	M6 direction input	16	M6 step input
17	M7 direction input	18	M7 step input
19	N.C.	20	N.C.

Table C.2: MDU-8 J3 connector pinouts. The connector is a 22 pin connector with 0.156'' spacing. A closed circuit between the limit input and ground means ``not at limit'', while an open circuit means ``at limit.''
