FORCE FEEDBACK MENU

n
•
When set to On, enables the force feedback function via the force feedback
output driver (pin 5).
The force feedback function is used to make a steering input device harder
to turn in proportion to the torque output of the steering motor. A force feedback
coil must be connected to the force feedback output driver (pin 5).
When set to On, the output will go to the Max Voltage (see below) when the
steering command exceeds the end stop until the input device changes direction.
When End Stop and End Stop Vibe are both set to On, the output will go to a
PWM mode of Max Voltage (vibrating according to Vibe On Time and Vibe Off
Time) when the steering command exceeds the end stop until the input device
changes direction.
Example: If Vibe On Time = 30 ms and Vibe Off Time = 70 ms, the vibration
would be 10 Hz, 30% duty cycle.
Sets the On time of the end stop vibration function.
Sets the Off time of the end stop vibration function.
n
•
Sets the minimum voltage output of the force feedback coil at an estimated
motor torque of zero. The minimum voltage corresponds to the minimum force.
n
•
Sets the maximum voltage output of the force feedback coil when the absolute
value of the estimated motor torque is at or above the set Max Torque. The
maximum voltage corresponds to the maximum force.
n
•
Sets an estimated steer motor torque at with the Max Voltage is output to the
force feedback coil. When setting this parameter it is useful to view the estimated
steer motor torque (Monitor » Steer Motor » Motor Torque).
