4.3 Installing the MH-Series SIGMA-5 Positioner – Type II
To level the headstock assembly cross-axially, proceed as follows:
1. Place a level on top of the housing, parallel to the faceplate.
2. Use the same three leveling bolts used above and adjust them until
the level is balanced, adjusting B + C equally.
3. Repeat the axial and cross-axial leveling steps until level readings are
achieved in both directions.
4. Drive the remaining leveling bolts down to their leveling shims.
5. Check level axially and cross-axially again. When level, tighten the
anchor system (customer-supplied) to the specified torque.
6. Tighten the six lock-nuts to the column base.

Connection to Motoman Controller
When the MH-Series SIGMA-5 Positioner assembly is delivered with a
Yaskawa Motoman robot, connections between the two usually have been
made at the factory, or if not, instructions for making connections can be
found in the system manual. See separate schematics and/or
documentation specific to the system.
4.3.4.2
Ground Cables – Type II
A ground cable bar is provided for attaching weld ground cables. Route
the ground cables from the power source, up through the bottom of the
Type II base, and attach to the ground cable bar.
