General Control Wiring Advisories

The figure below lists the control wiring requirements for all two wire control input
modes (P46 - [Input Mode] settings 1 and 4 – 9). The requirements specific to each
input mode are shown separately for that mode.

➊ Run input must be maintained. After a stop command, either a Run Forward or Run Reverse input

must be toggled to start the drive.

➋ Internal 12V supply. Contact closure or open collector input required. Refer to Appendix A for solid

state control input specifications.

➌ If both Run Forward and Run Reverse inputs are closed at the same time, an undetermined state

could occur.

➍ Control signal cable length is highly dependent on electrical environment and installation practices.

To improve noise immunity, TB3 Common must be connected to ground terminal/protective earth.
For control wiring installations greater than 15 meters (50 feet) in length, an optional 24V DC
interface module is recommended. See Appendix A for ordering information.
