NOVAK PIT WIZARD - Drive PWM Frequency

7 PIT WIZARD INSTRUCTION MANUAL
• DRIVE PWM FREQUENCY
–Measured in Hertz (Hz).
–Frequency at which the duty cycle information is being sent
from speed control to motor (How many times per second
the motor is being cycled on and off to control it’s speed).
–Drive PWM Frequency controls acceleration characteristics of
your vehicle with respect to trigger movement in the Full
Throttle direction (Figure 3). By changing the value of Drive
PWM Frequency you change the manner in which the vehicle
responds to transmitter trigger input.
–Increasing Drive PWM Frequency requires more initial trigger
movement to obtain the same given speed. Light vehicles feel
more controllable / Heavy vehicle more sluggish.
–Decreasing Drive PWM Frequency requires less initial trigger
movement to obtain the same given speed. Light vehicles are
harder to control at the low end (possibly spinning the rear
wheels) / Heavy vehicles are more reactive.
– This parameter can be used as a valuable tuning asset for
different types of motors and track conditions.
