Setting the Vehicle’s Unloaded Top Speed
The controller and vehicle should be configured as follows prior to setting the
maximum unloaded vehicle speed:
• Max Speed = 100%, all modes
• Drive Current Limit as established in tuning procedure
2
• Field Map = 50%
• Field Map Start = 50% of the specified drive current limit
• Field Min = manufacturer’s specified minimum (if available);
otherwise, 3 amps
• Load Comp = 0
• The vehicle should be unloaded
• The vehicle battery should be fully charged.
The vehicle should be driven on a flat surface in a clear area during this
procedure. Since the vehicle may initially be traveling at speeds in excess of the
final intended speed, precautions should be taken to ensure safety of test
personnel and anyone in the test area.
STEP 1. Select the programmer’s Program Menu and scroll down until the
Field Min parameter is at the top of the display.
STEP 2. Power up the vehicle and apply full throttle. While driving the
vehicle with full throttle applied, adjust the Field Min parameter
value to set the desired top speed. Increasing the Field Min value
decreases the vehicle’s top speed; decreasing the Field Min value
increases the vehicle’s top speed. CAUTION: Do not decrease the
Field Min parameter value below the motor manufacturer’s
recommended minimum field current value, and do not increase
it above 10 amps.
STEP 3. If the Field Min parameter value is increased to 10 amps and the
vehicle’s top speed has still not been sufficiently reduced, the Max
Speed parameter should be used to bring the vehicle top speed
down to the desired level. First, decrease the Field Min parameter
value, setting it to optimize smooth starting. Then adjust the
Max Speed parameter per Step 4 to bring the vehicle top speed
down to the desired level.
NOTE: If the Field Min parameter is set
too high, the high initial torque created by the high field current
may cause overly abrupt starts; this is why we recommend using
the Max Speed parameter in those cases where a moderate Field
Min setting does not sufficiently reduce the vehicle top speed.
STEP 4. Scroll up the Program Menu until the Max Speed parameter is at
the top of the display. While driving the vehicle with the Field
Min set at the value selected in Step 3, decrease the Max Speed
parameter value until the desired vehicle top speed is set.
