7 — INITIAL SETUP
e 1239E/1269E controller can be used in a variety of vehicles, which dier 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 the application.
BEFORE BEGINING
Correct values for the motor parameters (Motor Type, FW Base Speed, and Field Weakening) must be
determined individually for each motor:
For ACIM motors, use one of these three options to obtain ACIM motor data:
• Contact the Curtis distributor or support engineer with the manufacturer’s part number for
the motor. Curtis has a database of many motors for which the motor data has already been
determined. Motors in the Curtis database are assigned a number, which is the number used
for the ACIM Motor Type parameter.
• Send the ACIM motor to Curtis for testing on the factory motor dyno. The motor’s data will
be entered into the Curtis database and issue updated software (OS) with the appropriate
parameter values set to match the motor. Contact the Curtis distributor or support engineer
before shipping the motor.
• Use the ACIM Motor Characterization Procedure (Chapter 8A), which has the controller “learn”
the motor parameter data. The procedure should take about half an hour and can be done
on the vehicle. Go ahead and complete setup steps 1 through 10 of the Initial Setup before
conducting the ACIM characterization procedure.
For PMAC motors, use the PMAC Motor Commissioning Procedure (Chapter 8B). This PMAC motor
commissioning has the controller “learn” the motor parameter data. The procedure should take about
10 minutes and can be completed on the vehicle (with the drive wheels off the ground- free to rotate).
First complete these Initial Setup steps 1 through 9 before conducting the PMAC commissioning. For
PMAC motor data,
• Contact Curtis for the motor number that matches the application’s motor.
• Send the PMAC motor to Curtis for testing on the Curtis motor dynamometer (dyno) located
in California. Once characterized, the motor’s data goes into the Curtis database. Contact the
Curtis distributor or support engineer before shipping the motor. Shipping and characterizing a
motor required extra time. This process can take weeks to months, plus shipping.
ACIM:
If Curtis has provided the values for Motor Type, FW Base Speed, and Field Weakening and they are
“programmed” into the controller (see ACIM Field Weakening Control menu and the 1313/1314
Parameters), complete the these initial setup procedures prior to ne-tuning the motor. If using the
automated Motor Characterization Procedure, that will come later—aer completing steps 1 through
9. Following the motor characterization, then nish this Chapter’s Initial Steps prior to completing
the ne-tuning in Chapter 9.
