M5 LDC Operation and Configuration
M5 LCD Display Configuration for SM LRO Bicycles
Introduction to M5 LCD Display
- The speaker introduces the M5 LCD display commonly used with SM LRO bicycles, explaining its basic functionality.
- To turn the display on or off, hold down the mode button for a few seconds.
Accessing Configuration Options
- Enter configuration options by holding down both the up and down arrow buttons.
- It is advised to record or take pictures of current settings before making changes to avoid future issues.
Key Configuration Settings
Backlight Brightness and Speed Units
- Option 1 allows adjustment of backlight brightness (1 = darkest, 3 = brightest).
- Option 2 sets speed units: 0 for kilometers per hour and 1 for miles per hour.
Voltage Level and Screen Timeout
- Option 3 configures voltage level; example given is a setting for a 48V battery pack.
- Option 4 sets screen timeout duration, defaulting to 10 minutes before auto-off.
Power Levels and Tire Size
- Option 5 defines power levels at startup (0 = no power, 1 = power level one), with choices between three or five levels.
- Option 6 specifies tire size based on actual diameter rather than sidewall markings; example provided is a fat bike tire with a diameter of about 29 inches.
Additional Configuration Options
Speed Limit and Start Mode
- Option 8 sets maximum speed limit for assistance (up to 100 km/h or approximately 62 mph).
- Option 9 defines zero start mode: setting it to zero activates assistance immediately when pedaling, while one requires initial pedaling speed.
Power Mode and Sensitivity Settings
- In option 10, users can choose between pedal assistance only (0), throttle only (1), or both (2).
- Option 11 adjusts sensitivity of pedal assistance based on pedaling rotations; higher values require more effort before motor activation.
Initial Power Intensity and Magnet Count
- Option 12 determines initial power intensity upon detecting pedaling; ranges from least (1) to most powerful (5).
- In option 13, users specify the number of magnets on the crank sensor; available choices are five, eight, or twelve.
