1 — OVERVIEW
OVERVIEW
The Curtis PMC 1297 motor controller is an integrated controller that com-
bines two motor controllers in one: it controls both a separately-excited traction
motor and a series pump motor. Typical applications include walkie/rider pallet
trucks, low lifts, stackers, small order-pickers, small reach trucks, and other small
industrial vehicles.

integrated traction and
hydraulic system controller.
The 1297 controller offers smooth, silent, cost effective control of motor
speed and torque. The traction section includes a full-bridge field control and
a half-bridge armature control to provide full solid-state regenerative braking.
The pump section contains a half-bridge drive designed to provide smooth and
efficient control of a series pump motor. In addition to controlling the pump
motor, the 1297 controls the valves on the Lift cylinder’s hydraulic line and thus
controls the hydraulic path for Lift and Lower operations.
The 1297 controller is fully programmable through any of Curtis PMC’s
13XX programmers. In addition to configuration flexibility, the programmer
provides diagnostic and test capability.
The 1297 is also designed to work with the optional Curtis 840 Spyglass
data display and the optional Curtis PMC 1312 tiller multiplexer.
