OVERVIEW
Curtis 1232E/SE, 1234E/SE, 1236E/SE, and 1238E AC motor controllers
provide accurate, dependable, and highly ecient control of speed and torque
of AC induction motors (ACIM) and surface permanent magnet synchronous
motors (SPM).
ese AC controllers contain two microprocessors to provide exceptional
capability and functional safety. e primary microprocessor runs an advanced
eld-oriented AC motor control while simultaneously running VCL software in
an embedded logic controller. e second microprocessor continuously moni-
tors the operation of the system, redundantly measuring inputs, crosschecking
results, and verifying critical timing and operations.
VCL (Vehicle Control Language) is an innovative software programming
language developed by Curtis. Many electric vehicle functions are uniquely
built into the VCL code, and additional functions can be created by OEMs
as required. VCL opens new avenues of customization, allowing specic vehicle
application functions to be created quickly and easily within the motor controller
itself, often eliminating the need to use separate vehicle manager modules.
e CAN bus communications included within these controllers allow
these AC motor controllers to function as system CAN masters or CAN slaves
as part of an efficient distributed system. Inputs and outputs can be optimally
shared throughout the system, minimizing wiring and creating integrated
functions that often reduce the cost of the system.
ese controllers are the ideal solution for traction, hoist, dual drive, and
other motor drive and vehicle control needs.

1 — OVERVIEW
Fig. 1 Curtis AC induction motor controllers:
from left to right, models 1232SE, 1234E, 1236E, and 1238E.
e E and SE models look similar, and share the same standard features.
Like all Curtis controllers, the E and SE models oer superior operator control
of motor drive performance. Features include:
3Closed-loop speed and torque control for both induction (ACIM) and
surface permanent magnet (SPM) motors
3High efficiency, field-oriented motor control algorithms that enable
maximum possible motor torque generation for all operating conditions

Getting the most out of your Curtis controller
Read and apply the information in this manual. e Installation/Wiring, Initial
Setup, and Tuning Guide sections are critical to proper operation of your con-
troller. For technical support, contact the Curtis distributor where you obtained
your controller or the Curtis sales-support oce in your region.

INSTALLATION AND WIRING
MOUNTING THE CONTROLLER
e outline and mounting hole dimensions for the 1232E/SE controller are shown in
Figure2a, for the 1234E/SE controller in Figure2b, andforthe1236E/SEand1238E
controllers in Figure 2c. When an Ampseal plug housing is mated with the
35-pin logic receptacle, these controllers meet the IP65 requirements for envi-
ronmental protection against dust and water. Nevertheless, in order to prevent
external corrosion and leakage paths from developing, the mounting location
should be carefully chosen to keep the controller as clean and dry as possible.
It is recommended that the controller be fastened to a clean, at metal
surface with four 6 mm (1/4") diameter bolts, using the holes provided. A thermal
joint compound can be used to improve heat conduction from the controller
heatsink to the mounting surface. Additional heatsinking or fan cooling may
be necessary to meet the desired continuous ratings.

Working on electrical systems is potentially dangerous. Protect yourself against
uncontrolled operation, high current arcs, and outgassing from lead acid batteries:
UNCONTROLLED OPERATION — Some conditions could cause the motor to run out of
control. Disconnect the motor or jack up the vehicle and get the drive wheels off the
ground before attempting any work on the motor control circuitry.
HIGH CURRENT ARCS — Batteries can supply very high power, and arcing can occur if
they are short circuited. Always open the battery circuit before working on the motor
control circuit. Wear safety glasses, and use properly insulated tools to prevent shorts.
LEAD ACID BATTERIES — Charging or discharging generates hydrogen gas, which can
build up in and around the batteries. Follow the battery manufacturer’s safety recom-
mendations. Wear safety glasses.
