7.SAFETYFEATURES

SmartDriveDuo60 incorporates some safety features which make it robust and reliable motor           
driver.Belowarethedetaileddescriptionsforeachfeature.

a. InputError(ErrorLEDblinks2times)
Every time SmartDriveDuo60 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.

b. UnderVoltageWarning(ErrorLEDblinks3times)
Upon power on, SmartDriveDuo60 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.

c. OverVoltageProtection(ErrorLEDblinks4times)
Ifovervoltageisdetected(>45V),SmartDriveDuo60willnotoperate.

d. OverTemperatureProtection(ErrorLEDblinks5times)
SmartDriveDuo60 is equipped with a temperature sensor to monitor its operating          
temperature. It will gradually lower down the duty cycle percentage base on the            
