NOVAK PIT WIZARD - Brake PWM Frequency

9 PIT WIZARD INSTRUCTION MANUAL
• BRAKE PWM FREQUENCY
–Measured in Hertz (Hz).
–Frequency at which the duty cycle information is being sent
from speed control to motor for braking.
–Brake PWM Frequency controls deceleration characteristics of
your vehicle with respect to trigger movement in the Full Brake
direction (Figure 5). Changing Brake PWM Frequency allows
you to change the manner in which the vehicle responds to
brake trigger input.
–Increasing the Brake PWM Frequency will require more initial
trigger movement to obtain a given amount of braking. Light
vehicles brake more controllably under initial braking / Heavy
vehicles brake less reactively.
–Decreasing the Brake PWM Frequency will require less initial
trigger movement to obtain a given amount of braking. Light
vehicles are harder to control under initial braking (possibly
locking up the wheels) / Heavier vehicle are more reactive to
initial braking efforts.
