DESCRIPTION
The Accel Rate defines the time it takes the controller to accelerate from 0%
output to 100% output when full throttle is applied.
Larger values represent a longer acceleration time and therefore a gentler
start. For faster starts, adjust the Accel Rate to a smaller value.
When the throttle is moved from zero rapidly, the quick start feature is activated.
The Quick Start acceleration rate then replaces the normal acceleration rate (as
set by the Accel Rate parameter).
The Quick Start parameter can only be set to values smaller (faster) than
the programmed Accel Rate.
Defines the maximum requested motor speed at full forward throttle, as %
PWM. Partially-applied throttle is scaled proportionately; e.g., 40% applied
throttle corresponds to a request for 40% of the programmed Max Speed
value. Example: if Max Speed is set to 80%, a 40% applied forward throttle
corresponds to a 32% request (0.80 * 0.40 = 0.32).
Defines the maximum requested motor speed at full reverse throttle, as %
PWM. Partially-applied throttle is scaled proportionately; e.g., 40% applied
throttle corresponds to a request for 40% of the programmed Max Speed
value. Example: if Max Speed is set to 80%, a 40% applied reverse throttle
corresponds to a 32% request (0.80 * 0.40 = 0.32).
The Rev Speed parameter is in effect only with the "reverse input active"
wiring configuration or with a speed reduction resistor added to the circuit.
