About the 7FR7731

7FR7731 is a FlexPak 3000 regenerative drive controller that is manufactured by Reliance Electric. This particular drive is an integrator. Before installing the motor, the user must verify that the motor and the controller share the same horsepower rating. Coupled applications must have proper shaft alignment with the driven machine, or belted applications must have proper sheave/belt alignment. These option both minimize unnecessary motor loading. A protective guard must be installed around the motor’s exposed rotating parts if the motor is accessible while it is running. Wire the motor to the controller.

The lug model number can be useful to identify the correct lug and the associated wire size. 1LG is the basic catalog number. The next number is the number of conductors (1 or 2).

The last two numbers are the lug version number (01 through 99). Model numbers 1LG1101 and 1LG1101 require size 14-8 AWG wire. Model number 1LG1103 requires size 4-1/0 AWG wire. Model number 1LG1104 requires size 1/0-4/0 AWG wire. Model number 1LG1105 requires size 4/0-500 kcm wire. Model number 1LG1201 requires size 14-1/0 AWG wire. Model number 1LG1202 requires size 14-2/0 AWG wire. Model number 1LG1203 requires size 6-250 kcm wire. Model number 1LG1204 requires size 6-300 kcm wire.
