6 — VEHICLE PERFORMANCE ADJUSTMENT
The 1212/1212P controller’s adjustable parameters allow many aspects of vehicle performance to be
optimized. Once a vehicle/motor/controller combination has been tuned, the parameter values can be
made standard for that system or vehicle model. Any changes in the motor, the vehicle drive system,
or the controller will require that the system be tuned again to provide optimum performance.
The tuning procedures should be conducted in the sequence given, because successive steps build
upon the ones before. It is important that the effect of these programmable parameters be understood
in order to take full advantage of the controller’s features. Please refer to the descriptions of the
applicable parameters in Section 3 if there is any question about what any of them do.
Instructions are provided for the following four tuning steps.
Step 5: Setting the maximum speeds
Step 6: Setting the acceleration and deceleration rates
Step 7: Adjusting load compensation
Step 8: Fine-tuning the vehicle’s response smoothness.
Step 5: Setting the maximum speeds
The four maximum speeds with the speed limit pot in its maximum speed position are set by the
four Max Speed parameters:
M1/M2 Max Speed and M1/M2 Rev Max Speed.
The four maximum speeds with the speed limit pot in its minimum speed position are set by the
four Min Speed parameters:
M1/M2 Min Speed and M1/M2 Rev Min Speed.
Each of the maximum speeds is programmed as a percentage of the maximum possible speed. Set
each of the eight maximum speed parameters to give the desired performance.
