Product Overview 1-7
Control/Power Interface Boards Control/power interface boards are used to provide a link between
control boards (which are responsible for managing the drive), and
power components (which are closely associated with the actual drive
hardware and operations).
The following items are used to provide this interfacing:
• power stage interface board
• unit power supply board
• feedback board
These items are located on the control module in the disconnect bay
of the drive, and are arranged as shown below. Accessibility to the
power stage interface board and the unit power supply is gained by
lowering the front panel.
