The ACS6080 has a flexible modular design with standard and optional
cabinet units. Each cabinet unit is dedicated to a specific function.
Figure 3-2 ACS6080 drive example
The drive is assembled from standard and optional cabinet units. Each
unit is dedicated to a specific function.
Note:
For more information on the cabinet units in your drive, see the
Layout drawing in “Appendix C – Mechanical drawings”.
