8.1 RC INPUT MODE

In RC input mode, the speed and direction of the motor is controlled by the signal from the

standard hobby radio control transmitter and receiver, or a microcontroller generating the

similar signal.

NOTE: The RC transmitter must be ON before power up the SmartDriveDuo-10.

RC Input mode is selected by setting the SW1 & SW2 to 0 (Down). SW3 – SW6 can be

configured depending on the requirement of the user.

Mixed – The motor speed is controlled by channel RC1 and direction is

controlled by channel RC2. Recommended this mode if controlled using

RC transmitter/receiver.

Independent Right – Only motor Right will active, motor Left will

inactive. Motor Right is controlled by channel RC2.

Independent Left – Only motor Left will active, motor Right will

inactive. Motor Right is controlled by channel RC1.

Independent Both - Both motor is active and can be controlled

individually through channel RC1 and RC2. Recommended this mode if

controlled using Microcontroller.

Exponential Mode

SW5

0

1

Off – The speed is linear with the input signal. This is for low to

medium speed motor.

On –The response to input is exponential and thus soften the control

around the center zero speed point. This is suitable for high speed and

very sensitive motor.

MCU Mode

SW6

0

1

Off – The center point will be calibrated upon power up. Timeout

occurs after lost of signal for 100ms and the motor will be stopped for

safety purpose.

On – The center point is fixed at 1.5ms and the timeout feature is

disabled. Motor will continue to run with previous speed if new signal is

not detected. This is useful when a microcontroller is used to control the

motor. The microcontroller does not need to send the pulse continuously

to the SmartDriveDuo-10. Instead, it only needs to send a single pulse

when the speed or direction of the motor needs to be changed.

0 – OFF 1 – ON X – Don’t Care
