Great
Do you have the manuals for the drives? You will find them on the GLControls website.
Not sure if G&L manuals show the connection for sine/cosine encoders but as your motors are not standard ones for these drives you will sort of have to mix and match anyway.
Going by your drawing you will need to connect up as follows (I think),
Motor Drive CN2
A 1
B 2
C 3
D 4
E 5
F 10
G 6
H 14
K 12
L 11
M 13
P 8
If yours has a brake you will connect via the relay output (43 and 44) on CN1 connector and supply it with the required voltage.
You will also have to make up a custom motor profile, you can do that by using the Motor Config utility that will be in your windows start menu, programmes, DSAPro menu.
Need any help just shout.
