=A0 Sorry about the =3DA0 junk - something to do with Netscape...
The connection lists should be:
For the SPD-6U:
ELCO=A0=A0=A0 Signal=A0=A0=A0=A0 SLO-SYN 6-lead
A=A0=A0=A0=A0=A0=A0 Ph 1 Out=A0=A0 Red
B=A0=A0=A0=A0=A0=A0 Ph 2 Out=A0=A0 Red/White
C=A0=A0=A0=A0=A0=A0 Ph 3 Out=A0=A0 Green
D=A0=A0=A0=A0=A0=A0 Ph 4 Out=A0=A0 Green/White
E=A0=A0=A0=A0=A0=A0 Ph 1 Ret=A0=A0 Black
F=A0=A0=A0=A0=A0=A0 Ph 2 Ret=A0=A0 Black
H=A0=A0=A0=A0=A0=A0 Ph 3 Ret=A0=A0 White
J=A0=A0=A0=A0=A0=A0 Ph 4 Ret=A0=A0 White
For the SPD-3M
ELCO=A0=A0=A0 Signal=A0=A0=A0=A0 SLO-SYN 6-Lead
A=A0=A0=A0=A0=A0=A0 Ph 1+=A0=A0=A0=A0=A0 Red
B=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC
C=A0=A0=A0=A0=A0=A0 Ph 3+=A0=A0=A0=A0=A0 Green/White
D=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC

=A0 We are using the connections in the APS 'standard' (I think!).
For the SPD-6U:
ELCO=A0=A0=A0 Signal=A0=A0=A0 SLO-SYN 6-lead
A=A0=A0=A0=A0=A0=A0 Ph 1 Out=A0=A0=A0 Red
B=A0=A0=A0=A0=A0=A0 Ph 2 Out=A0=A0=A0 Red/White
C=A0=A0=A0=A0=A0=A0 Ph 3 Out=A0=A0=A0 Green
D=A0=A0=A0=A0=A0=A0 Ph 4 Out=A0=A0=A0 Green/White
E=A0=A0=A0=A0=A0=A0 Ph 1 Ret=A0=A0=A0 Black
F=A0=A0=A0=A0=A0=A0 Ph 2 Ret=A0=A0=A0 Black
H=A0=A0=A0=A0=A0=A0 Ph 3 Ret=A0=A0=A0 White
J=A0=A0=A0=A0=A0=A0 Ph 4 Ret=A0=A0=A0 White
This corresponds with Fig. 4.2 on page 17 of the ACS manual (Jan 1997).
This does not match up with any of the connection diagrams on page 24 or
25 of the
ACS manual.
I was able to succesfully move the motor with the following connections:
ELCO=A0=A0=A0 Signal=A0=A0=A0 SLO-SYN
A=A0=A0=A0=A0=A0=A0=A0 Ph 1+=A0=A0=A0 Red
B=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC
C=A0=A0=A0=A0=A0=A0=A0 Ph 3+=A0=A0=A0 Green/White
D=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC
E=A0=A0=A0=A0=A0=A0=A0 Ph 1-=A0=A0=A0 Red/White
F=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC
H=A0=A0=A0=A0=A0=A0=A0 Ph 3-=A0=A0=A0 Green
J=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 NC
This corresponds with Fig. 5.2 on page 25 of the ACS manual.
Interestingly enough, we had previously tried the microstepper drives
with an
8-lead motor and found no problems.
