detects that the vehicle has reached rest, or is starting to roll back, the EM brake
will be applied immediately to prevent further vehicle movement.
step 1. Set the following parameters:
• FLD BRAKE = On
• EMB DELAY = a low value (e.g., 3 seconds)
• FLD BRAKE MAX = FIELD MIN , or higher
• FLD BRAKE RATE = a low value (e.g., 2).
step 2. Drive up a hill and release the throttle. The vehicle should slow
to a stop and the EM brake should drop just as the vehicle be-
gins to roll backwards. If the vehicle rolls backwards excessively,
increase the
FLD BRAKE MAX .
step 3. Drive down a mild slope and release the throttle. The vehicle will
slow down but may not reach a complete stop depending on the
gradient of the slope. You should feel the field braking torque,
followed by the EM brake being applied. If the EM brake is
applied too early, increase the
FLD BRAKE MAX and the EMB DELAY .
step 4. After adjusting these parameters, drive the vehicle on flat ground
to confirm that the EM brake timing is acceptable. To avoid
unnecessarily abrupt stops, the parameters should be set so that
when driving on flat ground the vehicle reaches rest before the
EM brake is applied.
