Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022
ACIM
For AC Induction Motor (ACIM) motors, use one of these three options to match the motor in
the vehicle:
1. Contact the Curtis distributor or support engineer with the motor manufacturer's part number.
2. Send the ACIM motor to Curtis for testing on the Curtis motor dynamometer (dyno) located
3. Use the in-vehicle Induction Motor Characterization Procedure (later in this chapter), in which
ACIM motors use the quadrature Encoder. Contact Curtis if an ACIM application will use a Sin/
Cos sensor (encoder).
Correct values for the motor parameters (Motor Type, FW Base Speed, and Field Weakening) must
be determined individually for each motor.
PMAC
For permanent magnet AC (PMAC) motors, use one of these two options to match the motor in
the vehicle:
1. Contact the Curtis distributor or support engineer with the motor manufacturer's part number.
2. Send the PMAC motor to Curtis for testing on the Curtis motor dynamometer (dyno) located
PMAC motors use the Sin/Cos sensor type Encoder. Contact Curtis if a PMAC application
will use a different type of rotor-position sensor. PMAC always requires additional in-vehicle
motor commissioning.

diagrams based upon the default assignment settings for the application. Each application can be
different from these figures. Turn on the controller by closing the keyswitch circuit. Using a PC,
connect the Curtis Integrated Toolkit
in Appendix D. Within the toolkit's Launchpad window, highlight the controller that is being-setup,
then click to open the Programmer application tool. Ensure the controller and CIT project have
matching device profiles. A 1313 HHP can also set/change parameters, yet if using VCL, the project/
application must use the Curtis Integrated Toolkit

Curtis has a database of induction motors (cdev 4.0) for which the motor data has already been
determined. Each induction motor in the Curtis database is assigned a number, which is the
number used for the Motor Type parameter (IM_Motor_Type, 0x3635).
in California. Once characterized, the motor's data goes into the Curtis database. This requires
new software (device profile revision) with the appropriate parameter values set to match the
motor. Contact the Curtis distributor or support engineer before shipping the motor. Shipping and
characterizing a motor requires extra time. This process can take weeks to months, plus shipping.
the controller "learns" the motor data as installed in the vehicle. Once set up, the procedure takes
about half an hour with the vehicle drive wheels off the ground. Completing the characterization
involves operating the vehicle in a test area (wheels on the ground tests). When choosing
this option, complete steps 1 – 21 of these Initial Setup steps before conducting the ACIM
characterization procedure.
