User Manual

14 / 17

When the voltage output is between 4.75V and 5.25V, the load will change from

25% at maximum to 50% then back to 25%, or from 50% at maximum to 75% then

back to 50%. The slope is 0.5A/us. The frequency is 100Hz. Output overshoot is

lower than ±5%.

Protection requirement

Short circuit protection: when outputting short circuit, the input power will lower

and will not have any affect. After ending the short circuit, the system will recover

automatically.

Overcurrent protection

OCSET: within 110%-180% of maximum load (with rated voltage), when outputting

overcurrent, the output will go to hiccup mode. After ending the overcurrent, the

system will recover automatically.

Configure RPLIDAR A3 Scan Frequency

The motor speed control signal MOTOCTL can be configured directly via the USB

adapter of RPLIDAR A3. Therefore, the RPLIDAR A3’s scan frequency can be

modified by invoking the related functions in the SDK to configure the motor

speed.

Without the USB adapter, users can also control the speed by setting the PWM

duty cycle of MOTOCTL. Please note that the PWM frequency is 20kHz. For more

detailed parameter and index, please refer to the datasheet.

Please refer to the RPLIDAR protocol and application note for more information

and the SDK for the sample code on RPLIDAR scan frequency.

SDK Usage

SLAMTEC provides RPLIDAR SDK support on both Windows and Linux platform.

And users can embed the SDK source code to other operational system or

embedded system quickly. Please refer to the SDK document for more information.
