| Definition |
Place the PZT platform horizontally for installation, with the moving surface located above the PZT platform and parallel to the horizontal plane.
PS: Default direction for carrying capacity in the parameter table
|
Place and install the PZT platform vertically, with the moving surface parallel to the direction of gravity
|
Place the PZT platform horizontally, but the moving surface is located below the PZT platform |
