Control Wiring 5-5 MN766
5.5 Operating Modes
The operating modes defi ne 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 Operating Mode parameter in the
Level 1 Input Setup Programming Block (P1401).
Operating modes include:
• Keypad • Standard Run 2Wire • Standard Run 3Wire • 15 Preset Speeds
• Fan Pump 2Wire • Fan Pump 3Wire • Process Control* • 3 Spd Ana 2Wire
• 3 Spd Ana 3Wire • Electronic Pot 2Wire • Electronic Pot 3Wire • Network
• Profi le Run* • 15 Preset Position* • Bipolar • Pulse Follower*
• PLC*
* To view and change parameters associated with these modes, Operating Mode (P1401) must be set to the respective
mode. For example, this means Process Control parameters will not appear on the keypad for selection unless Level 1, Input
Setup, Operating Mode (P1401) is set to “Process Control”.
Each mode requires connections to the J1, J2 and J3 terminal strips. The terminal strips are shown in Figure 5-1. The
connection of each input or output signal is described in the following pages.
5.5.1 Keypad
The Keypad mode allows the control to be operated from the keypad. In this mode only the Enable input is required.
However, the Stop and External Trip inputs may optionally be used. All other Digital Inputs remain inactive. The Analog
Outputs and Digital Outputs remain active at all times.

*Note: Remove factory jumper from J2-8 and J3-24 before connecting switch at J2-8.
J2-8 CLOSED allows normal control operation.
OPEN disables the control and motor coasts to stop.
J2-11 Optional STOP input (not required).
CLOSED allows normal control operation.
OPEN motor coasts or brakes to stop if Level 1 Keypad Setup block, Local Hot Start parameter is set to “ON”.
J2-16 Optional External Trip input (not required). If used, you must set Level 2 Drive Protect block, External Trip to “ON”.
CLOSED allows normal operation.
OPEN causes an External Trip to be received by the control (when programmed to “ON”).
