Safety Features - Cytron SmartDriveDuo-30 User Manual

7. SAFETY FEATURES
SmartDriveDuo-30 incorporates some safety features which make it robust and reliable
motor driver. Below are the detailed descriptions for each feature.
1. Input Error​ (​ E rror LED​
Every time SmartDriveDuo-30 is power up, the input data must be 'stop' (for RC, Analog,
PWM input mode). This feature prevent the driver from sudden run, especially when the
driver accidently reset.
2. Under Voltage Warning​ (​
Upon power on, SmartDriveDuo-30 will automatically detect the number of cells for the
battery. If it is set to LiPo, when the input voltage falls below 3.0V per cell during
operation, the error LED will blink to warn the user. However, the power to the motor
will be maintained and will not be cut out. Thus, it is user's responsibility to stop the
motor driving and replace battery to avoid further damage to the battery. If other types
of battery is used to power the board (e.g NiMH, NiCD, SLA), the under voltage warning
will still be shown. In this case, user may ignore the warning and he/she needs to
estimate when to replace the battery by him/herself.
3. Over Voltage Protection​ (​
If over voltage is detected (> 35V), SmartDriveDuo-30 will not operate.
4. Over Temperature Protection​ (​
SmartDriveDuo-30 is equipped with a temperature sensor to monitor its operating
temperature. It will gradually lower down the duty cycle percentage base on the
temperature as shown below:
TEMPERATURE (°C)
50 - 70
70 - 100
