Inverter Control Board Connections

Ten operating modes are available in the Series 22H vector control. These operating

modes define the basic motor control setup and the operation of the input and output

terminals. After the circuit connections are completed, the operating mode is selected by

programming the Level 1 Input block, Operating Mode parameter.

Available operating modes include:

•Keypad Control

•Standard Run, 3 Wire Control

•15 Speed, 2 Wire Control

•Three Speed, 2 Wire Control

•Three Speed, 3 Wire Control

•Serial

•Bipolar Speed or Torque

•Process Control

•EPOT, 2 Wire Control

•EPOT, 3 Wire Control

Each mode requires connections to the J1 terminal strip (except keypad and serial

modes, all connections are optional). The J1 terminal strip is shown in Figure 3-16. The

connection of each input or output signal is described in the following pages.

Serial Mode The Serial operating mode requires one of the optional Serial Interface expansion boards

(RS232 or 422/485). Installation and operation information for these serial expansion

boards is provided in Serial Communications expansion board manual MN1310. This

manual is shipped with the serial expansion board.
