The motorboard will not function and there will be no indication as to the cause of failure.

Navigation menu Personal tools Micrpchip account Log in. One turn of the wheel is at best inches The motorboard has an automatic low power shut off.

When you turn the motorboard ON, the green light goes on then off, then the yellow light goes on then off then the red light goes on then off and then the green light goes on solid. Then the operator pushes to go.

This saves significant amounts of battery power and microochip the motorboard from starting accidentally. If low power is detected the red LED will blink, and power will be shut off completely. Because there is no indication that the motor is moving less kicrochip 3mph, if the optical wheel fails for any reason the motorboard will assume that 3mph has not yet been reached. The Roth motorboards “maximum” speed of 18mph translates to optical pulses per second.

Actually it operates at Hz measured.

Retrieved from ” http: Microxhip page was last modified on 23 Marchat The controller monitors the speed of one of the motors the one with a optical wheel “chopper” attached to an elongated motor shaft. Privacy policy About Motorboards Disclaimers Mobile view. Since there are eight optical slots on the chopper per turn, this means optical pulses per turn of the wheel.

When the battery is almost dead, the red light will blink and the buzzer on na899 motor contoller PCB will beep on and off 1 second on, 4 seconds off until the battery reaches the low power shut off. The current code cannot be read because the “Code Protect” bit has been set, but it is possible to erase the chip and program it with new code.

Motorboard Controller Source Code (Open Source) – Motorboards

If the speed of this motor is less than 3mph, no power will be provided to the motors. When the battery gets critically low, the RED light will illuminate. This prevents power from being applied to the motors until they are at least rotating at 3mph. The motor makes approximately The speed is controlled linearly, and no attempt is made microxhip maintain a given speed for a given throttle position.
