INITIAL SETUP
The 1234/36/38 controllers can be used in a variety of vehicles, which differ
widely in characteristics. Before driving the vehicle, it is imperative that these
initial setup procedures be carefully followed to ensure that the controller is set up
to be compatible with your application. The first step is to contact Curtis:
* * * BEFORE YOU START * * *
Correct values for the AC motor parameters (Motor Type,
FW Base Speed, and Field Weakening) must be determined
individually for each AC motor. You can determine these
values in any one of the following ways:
➡ Contact Curtis with the manufacturer’s part num-
ber for your motor. We have a database of many
AC motors for which we have already determined
the correct motor parameter settings.
➡ Use the AC Motor Characterization Procedure,
which has the controller “learn” the AC motor
parameter data. The procedure should take about
30 minutes to complete and can be done on the
vehicle. Contact Curtis for the procedure. Go
ahead and complete setup steps

before conducting the characterization procedure.
➡ Send your AC motor to Curtis for testing on the
motor dyno. Your motor’s data will be entered
into the Curtis database and we will send you the
appropriate parameter values to enter into your
controller. Contact Curtis before shipping your
motor.
Once you have obtained the correct values for Motor Type, FW Base Speed,
and Field Weakening and have set them on your controller (see Motor Control
menus, page 62), you can start conducting the setup procedures. Note: If you
will be conducting the AC Motor Characterization Procedure, that will come
later.
Before starting the setup procedures, jack the vehicle drive wheels up
off the ground so that they spin freely. Double-check all wiring to ensure it is
consistent with the wiring guidelines presented in Section 2. Make sure all con-
nections are tight. Turn on the controller and plug in the 1311 programmer.
1 Motor encoder (see page 53)
Set the Encoder Steps parameter to the correct setting for your motor’s position
encoder. This information is typically available from the motor manufacturer. If
