5 — INITIAL SETUP
over the entire range of brake pot movement. e value displayed for Mapped
Brake should be = 0% through the range of brake pot motion that is considered
neutral. e displayed Mapped Brake should be = 100% through the range
of motion that is considered max. Contact your Curtis distributor or support
engineer to resolve any issues about the brake setup before continuing with
the setup procedure.
8 Motor Technology & Feedback Type (see pages 55 and 61)
Set the Motor Technology parameter to match the motor used in your application
(0 = ACIM, 1 = SPM).
Set the Motor Feedback Type parameter based on the Motor Technology setting:
Feedback Type = 1 (quadrature position encoder) for ACIM,
Feedback Type = 2 (sin/cos sensor) for SPM.
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 (Section 6a), it can determine the encoder
steps, but only for encoders with 32, 48, 64, or 80 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 Characteri-
zation Procedure (Section 6b).
9 Faults (see Section 9)
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 setup procedure. Use
Section 9 for help in troubleshooting. Contact your Curtis customer support
engineer to resolve any fault issues before continuing with the setup procedure.
bk Setting feedback direction (see page 61)
With the vehicle drive wheels still jacked up, no faults present in the controller,
the interlock O (as verified in the Monitor
» Inputs menu, page 74), 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 (page 79) 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
