12.5.6 Outline drawings
The actual dimensions may be 1 to 3mm larger than the drawing dimensions. Design the machine side with
allowances.
When running the cables to the load side, take care to avoid interference with the machine. The dimensions in
the drawings without tolerances are the reference dimensions.
The inertia moments in the table are the value calculated by converting the total value of inertia moment for
servo motor and electromagnetic brake to the servo motor shaft.
