Step 20: Clear Faults
Cycle the keyswitch to clear any parameter change faults. Use the programmer to check for faults. Clear and
resolve all faults, including those in the Fault History (Programmer » System Monitor » Fault History » Clear
History) before continuing with the initial setup.
Use Chapter 7 for help in troubleshooting. Contact your Curtis customer support engineer to resolve any
fault issues.
Step 21: Setting Motor Feedback Direction
ACIM:
is step “hand turns the motor” to verify the encoder direction. With the vehicle drive wheels still
o the ground (vehicle jacked up on stable stands), no faults present, the interlock O, and both
the throttle and brake in neutral (Mapped rottle = 0% and Mapped Brake = 0%) as veried in the
Programmer » System Monitor » Inputs menu, the encoder direction can be checked.
While viewing the Motor RPM in Programmer » System Monitor » AC Motor » Motor RPM, turn the
motor by hand and observe the sign of Motor RPM. Positive values are forward and negative values
are 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 Encoder
Direction parameter is correct. If getting a negative Motor RPM when rotating the motor forward,
change the Swap Encoder Direction parameter. See Programmer » AC Motor Setup » Quadrature
Encoder » Swap Encoder Direction. Cycle the keyswitch and repeat the procedure until you are
satised that the Swap Encoder Direction parameter setting is correct.
Hint: If using the 1313 hand held programmer, add the frequent “tuning” parameters and monitor
variables to the Favorites menu for quick changes and checks. e equivalent in CIT is creating
a dashboard.
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 21 is not applicable to SPM motors. e present device prole (2.3.0.3) does not support SPM.
Step 22: Motor Characterization
If the motor is an ACIM motor, choose:
(a) Already have soware with the motor data programmed to match the motor. e pre-set motor
data soware 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.
(b) Use the in-vehicle ACIM Motor Characterization Procedure (next section). 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.
If the vehicle will use the emergency reverse feature, it is imperative the reverse direction
(negative Motor RPM) is set correctly so that when the Emergency Reverse input is active the
motor will rotate in the reverse direction, away from the operator in a Class III application.
