OVERVIEW
Curtis 1268 controllers are separately excited motor speed controllers designed for
use in a variety of transport vehicles. These programmable controllers are simple
to install, efficient, and cost effective. Typical applications include heavy-duty
golf carts, personnel transports, burden carriers, and other utility vehicles.
The 1268 controller offers smooth, silent, cost effective control of motor
speed and torque. The speed sensor input allows superior closed-loop control
for regulating vehicle speed. Unique braking parameters allow simple, intuitive
deceleration tuning. A full-bridge field winding control stage is combined with
a half-bridge armature power stage to provide solid state motor reversing and
regenerative braking power without additional relays or contactors.

These controllers are fully programmable by means of the optional hand-
held programmer or PC programming station. Use of a programmer provides
diagnostic and test capability as well as configuration flexibility and the ability
to easily transfer settings from one controller to another.
