VEHICLE PERFORMANCE ADJUSTMENT

The 1228 controller is a very powerful vehicle control system. Its wide vari-
ety of 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 1228 controller's powerful 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.

Setting the maximum speeds

Setting the acceleration and deceleration rates

7 Adjusting load compensation
8 Fine-tuning the vehicle's response smoothness.
Setting the maximum speeds
5
The four maximum speeds with the speed limit pot in its maximum speed
position are set by the speed parameters containing the words
M1 MAX SPD
M2 MAX SPD
M1 REV MAX SPD
M2 REV MAX SPD
The three maximum speeds with the speed limit pot in its minimum speed
position are set by the speed parameters containing the words
M1 MIN SPD
M2 MIN SPD
REV MIN SPD
Each of the maximum speeds is programmed as a percentage of the maximum
possible speed. Set each of the seven maximum speed parameters to give the
desired performance.
Setting the acceleration and deceleration rates
6
The acceleration and deceleration functions have been designed to provide
smooth throttle response when maneuvering at low speeds and snappy throttle
response when traveling at high speeds. This is accomplished by defining ac-
celeration/deceleration rates at each end of the speed limit pot's range. The
