Connected the input cables from DGS to these piezo drivers. The assignment is:

• ALS-X STM1 -> POP GrM3
• ALS-X STM2 -> POP GrM4

To clarify the naming assignment, I added relevant labels on the piezo drivers (see the attached photo).

The channel assignment is

• ALS-X STM1-1, 2, 3 -> X, Y, Z -> 0, 120, 240 deg
• ALS-X STM2-1, 2, 3 -> X, Y, Z -> 0, 120, 240 deg

Please prepaire carefully a relevant AC taps, and connect the AC cables from these drivers just before you would start the final adjustment of them.
