Initial Setup - Kohler Curtis F Series Manual

INITIAL SETUP

The F-Series controllers are suitable for a variety of vehicles that differ widely in characteristics.
Consequently, not all parameters or control modes may be appropriate to a given application, nor
are the default parameter values. Therefore, before driving the vehicle, it is imperative to follow these
initial setup steps to ensure that the controller parameter settings are suited to the application. To gain
a better insight into the parameters and their settings, completely read this chapter before conducting
the individual commissioning steps. Review and set up the methods to program the application's
controller(s) as summarized in Appendix D.
BEFORE BEGINNING
WARNING
TRACTION MOTOR SELECTION
All applications must complete a revised motor commissioning process for new and existing
applications changing from an E-series to F-Series controllers.
The commissioning (controller/application setup) includes setting the non-motor parameters
followed by the applicable motor setup. For planning purposes, outlined here is what the ACIM and
PMAC options entail, with the actual motor commissioning routines following later in this chapter.
In all cases, to ensure the correct motor commission, the Motor Setup Needed fault will be present
in the CIT/programmer. In addition, the Motor Temp Sensor fault is set. Both of these are "normal"
default settings and designed to ensure the final application will operate correctly.

Before beginning these setup steps, jack the vehicle's drive wheels up off the ground so that they
spin freely and the vehicle is stable— especially when the drive wheels accelerate, decelerate,
or spin at higher speeds. Reference the vehicle-wiring diagram when assigning the controller's
inputs, outputs and control functions. Double-check all wiring to ensure it is consistent with
the wiring guidelines described in Chapter 2. Finally, check the torque of all the electrical and
mechanical fasteners before proceeding with these setup steps. Ensure the vehicle harness and
power cables are secure, and that there are no pinch or rub points that can cause a short circuit.
Never spin pneumatic or solid tires beyond the manufacturers' maximum rpm specifications.
When commissioning and tests require the vehicle to be on the ground, able to operate/drive;
ensure there are no tools and objects on/near the traction motors/drivetrain, the moving steering
components/system, the wheels, and moving parts/accessories. Always operate the vehicle in a
safe test area, where protection for personnel and property from uncontrolled operation is verified.
Ensure the vehicle brakes operate, including the EM Brake and Emergency Reverse, if so equipped.
• The existing PMAC parameters cannot be copied across from EOS to FOS.
• For ACIM, the parameters are transferable from EOS to FOS. However, the current regulator gains
are not transferable (now removed from the ACIM motor model number) and are now part of the
FOS motor commissioning routine.
• For applications entering motor data by hand, this requires a Curtis Engineer (applies to ACIM
Motor Type = 0).
• The ACIM motor types are user (OEM Factory) selectable, yet require running the current
regulator and base speed routines. Field weakening is optional, yet recommended for efficiency.
