To understand the concept of a regenerative drive, the operation of an elevator can be used.
If one were to enter the elevator on the first floor and press 10, the motor and control would
have to lift the elevator against gravity. In this mode, the drive would operate like a
conventional speed control which is called “motoring” (the applied load is opposite to the
direction of motor rotation). When the elevator is at floor 10 and floor 1 is pressed, gravity will
try to pull the elevator car down faster than the speed for which it is set. The control will then
provide reverse torque to keep the car form falling faster than the set speed. This operation
is regeneration (the applied load is in the same direction as the direction of motor rotation).

SETTING SELECTABLE JUMPERS.
The KBRG-213D has customer selectable jumpers which must be set before the control can
be used (refer to fig. 1, p. 3). Bold indicates factory setting. See fig. 6, p. 5 for location of
jumpers.

A. J1, J2 – Input AC Line Voltage – Select proper input line voltage, 115VAC or 230VAC,
by placing both J1 and J2 in the correct corresponding position, “115" or “230.” (See fig.
1, p. 3.)
