Traction Motor Setup Guide - Kohler Curtis F Series Manual

Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022
Steps 1–4
Steps 5–8
Steps 9–21
These initial setup steps do not work through all the Speed Mode/Speed Mode Express parameter-
by-parameter. See Chapter 4, Programmable Parameters, for a full description of each parameter,
its usage, and its available range. Some parameters cannot be fully set until the traction motor and
vehicle tuning.
Finally, should the application differ from Figures 12–15, or use different hardware/control devices,
then use these steps as a setup-process guideline.

Step 1: Motor Type. Set the Motor Type
The commissioning/characterization will come later.

Will setup most of the motor settings, leaving some parameters for the final motor
or vehicle response tuning.
Will setup the controller to match the application. Here is where the Analog Inputs,
I/O Assignments, Outputs (drivers), External Supplies, and Current Limits are set.
Covers the application's functional options. These steps generally cover how the
operating system or VCL will process, control, or tune the Throttle, Brake, CAN
Interface, Main Contactor, EM Brake Control, Emergency Reverse, Interlock
Braking, Max Speed Supervision, Motor Not Stopped, Hazardous Movement, Motor
Braking Supervision, and the IMU.
See Programmer » AC Motor Setup » Induction Motor » Motor Type
2.1 Enable the Motor Temperature Sensor by setting the Sensor Enable parameter = On.
See Programmer » AC Motor Setup » Temperature Sensor » MotorTemp_Sensor_Enable
2.2 Set the Sensor Type parameter to the predefined type that corresponds to the motor
temperature sensor. The motor temperature (thermistor) sensor connects between the Motor
Temp and I/O Ground as shown in Controller Wiring Diagram. See Programmer » Motor
Setup » Temperature Sensor » menu.
Check whether the Sensor Type and Sensor Offset parameter settings and the motor-thermistor
connections yield the correct motor temperature by reading the Temperature parameter, which
is displayed in the Temperature Sensor menu, or in the CIT toolkit's Programmer app, » System
Monitor » Motor menu » Temperature.
If the motor temperature is not correct, double-check the motor temperature control parameters
Sensor Enable, Sensor Type, and Sensor Offset. Ensure that the thermistor wiring orientation
has its negative (ground) side connected to ground input e.g., pin 18 on 35-pin controllers, pin
12 of 23-pin controllers.
To set up a custom sensor type, set Type = Custom (Type 0 = Custom). Using the temperature
sensor datasheet, set the six sensor resistance parameters to match the six corresponding sensor
temperature parameters.
To proceed if the correct motor temperature is not displayed or if a motor temperature sensor
isn't used, or while awaiting a custom sensor setup/VCL, the initial setup procedure can
continue, but only if the Sensor Type (MotorTemp_Sensor_Enable) parameter is set to Off.
If the Programmer displays the correct motor temperature, complete this step by setting the
remaining motor temperature control parameters: Sensor Offset (if needed or not already
completed, above), Braking Thermal Cutback Enable, Temperature Hot, Temperature Max,
and MotorTemp LOS Max Speed. See Chapter 4 for these parameters' descriptions and ranges.
