12 PIT WIZARD INSTRUCTION MANUAL
• DRAG BRAKE FREQUENCY
–Measured in Hertz (Hz).
–Frequency at which duty cycle information is being sent from
Cyclone to motor for Drag Braking during Neutral/Deadband.
–The Drag Brake Frequency (Figure 9) controls deceleration
characteristics of vehicle with Drag Brake during Neutral/
Deadband. Changing the Drag Brake Frequency changes the
manner in which the vehicle responds to Drag Brake.
–The Drag Brake Frequency affects the Drag Brake only when
the Drag Brake Toggle is OFF.
–Decreasing the Drag Brake Frequency makes the braking more
reactive during the Neutral/Deadband.
–Increasing the Drag Brake Frequency makes the braking more
subtle during Neutral/Deadband.
–With Drag Brake Toggle OFF, Drag Brake can be used with a
higher setting of Drag Brake Value (on Pit Wizard) along with
a high setting of Brake PWM Frequency, and increased Minimum
Brake setting (Brake Pot), to obtain battery regeneration with-
out noticable increased braking effects. With Drag Brake Toggle
ON, Brake PWM Frequency is adjusting the frequencies of
both the brakes in the Neutral/Deadband area and the brakes
controlled by brake trigger movement.
