3 — PROGRAMMABLE PARAMETERS: Battery & Acceleration Parameters
VOLTAGE
The battery voltage parameter sets the overvoltage and undervoltage protec-
tion thresholds for the controller and battery. Overvoltage protection cuts back
regenerative braking to prevent damage to batteries and other electrical system
components due to overvoltage; undervoltage protection prevents systems
from operating at voltages below their design thresholds. The battery voltage
parameter can be set at 2 or 3, and should always be set to the system’s nominal
battery pack voltage:

M1–M4, DRIVE C/L
The drive current limit parameter allows adjustment of the maximum current
the controller will supply to the motor during drive operation. This parameter
can be limited to reduce the maximum torque applied to the drive system by the
motor in any reduced performance mode. The drive current limit is adjustable
from 50 amps up to the controller’s full rated armature current. (The full rated
current depends on the controller model; see specifications in Table D-1.)
The drive current limit is tuned as part of the vehicle performance adjust-
ment process (Section 5).
M1–M4, ACCEL RATE
The acceleration rate defines the time it takes the controller to accelerate
from 0% drive output to 100% drive output. A larger value represents a longer
acceleration time and a gentler start. Fast starts can be achieved by reducing
the acceleration time, i.e., by adjusting the accel rate to a smaller value. The
acceleration rate is adjustable from 0.1 to 3.0 seconds.
The acceleration rate is tuned as part of the vehicle performance adjust-
ment process (Section 5).
QUICK START
Upon receiving a sudden high throttle demand from neutral, the quick start
function causes the controller to momentarily exceed its normal acceleration
rate, in order to overcome vehicle inertia. The quick start algorithm is ap-
plied each time the throttle passes through neutral and the controller is not in
