WARNING
Make sure that the Feedback Type matches the feedback device used on the motor, and that you are
using the right type of device for your motor. If there is not a match, stop the setup procedure until
a compatible motor and feedback device are obtained and installed.
If your application uses an ACIM motor (which must use a quadrature encoder), program the
Encoder Steps parameter to the correct setting. is information is typically available from the motor
manufacturer. If the ACIM Characterization Procedure is used (Chapter 8A), it can determine the
encoder steps, but only for encoders with 32, 48, 64, or 80 pulses per revolution (ppr).
Setting the Encoder Steps parameter improperly may cause vehicle malfunction, including
uncommanded drive.
If your application uses an SPM motor (which must use a Sin/Cos sensor), the Sin/Cos min and max
voltages will be learned during the SPM Characterization Procedure (Chapter 8B).
Step 9: Faults (see Chapter 11)
Cycle KSI (to clear any parameter change faults) and use the programmer to check for faults in the
controller. All faults and errors (including those in the History le) must be cleared before continuing
with the initial setup. Use Chapter 10 for help in troubleshooting. Contact your Curtis customer
support engineer to resolve any fault issues before continuing with the setup procedure.
Step 10: Setting Feedback Direction (see page 59)
ACIM:
With the vehicle drive wheels still jacked up, no faults present in the controller, the interlock O (as
veried in the Monitor » Inputs menu), and both the throttle and brake in neutral (Mapped rottle =
0% and Mapped Brake = 0% in the Monitor » Inputs menu), the encoder direction can be checked.
Use the Monitor » Motor menu to view the Motor RPM display. Turn the motor by hand and observe
the sign of Motor RPM. Positive is forward and negative is reverse. If you get a positive Motor RPM
when you rotate the motor in the forward direction, and a negative Motor RPM when you rotate
the motor in the reverse direction, the Swap Feedback Direction parameter is correct and should
not be changed. If you are getting negative Motor RPM when rotating the motor forward, the Swap
Feedback Direction parameter must be changed. Cycle KSI power and repeat the procedure until
you are satised that the Swap Feedback Direction setting is correctly set. If the vehicle will use the
emergency reverse feature, the reverse direction (negative Motor RPM) must be correctly selected
so that when the Emergency reverse input is active the motor will rotate in the reverse direction.
Contact your Curtis distributor or support engineer to resolve any issues about encoder direction
or emergency reverse before continuing with the setup procedure.
SPM:
Step 10 is not applicable to SPM motors. Go to the next step for SPM motor in-vehicle auto-
characterization.
Step 11: Motor Characterization
If your motor is an ACIM motor, you must either:
(a) Already have soware with the motor data programmed to match your motor. e pre-set motor
data soware is usually the result of contacting your Curtis distributor or support engineer and
getting a match between your motor and the Curtis ACIM motor database, or by shipping a motor
to Curtis for dyno characterization.
or (b) Use the in-vehicle ACIM Motor Characterization Procedure (Chapter 8A). is procedure
will set the direction, may set the Encoder Steps, learn ACIM motor data, and set the FW Base Speed
and Field Weakening Drive.
