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.
