Technical Deep Dive
The ToSeven T24 Display Interface
The rugged, high-clarity 2.4-inch TFT command center engineered for total control, advanced parameter tuning, and real-time diagnostics on ToSeven DM01 and DM02 mid-drives.
T24 Display Operation Manual
In modern electric bicycle conversions, the display is far more than a simple speedometer—it is the central processing interface connecting the rider to the motor's Field-Oriented Control (FOC) vector drive. The ToSeven T24 Display serves as the primary technical control center across ToSeven's entire mid-drive motor lineup. Engineered to balance extreme operational durability with deep system access, the T24 bridges real-time telemetry, advanced torque sensor calibration, and diagnostic reporting directly to your handlebars.

Section 2: Menu Architecture, Security & Vehicle Metrics
Two-Stage Authentication & System Parameter Configuration
To prevent accidental parameter changes while allowing full customizability, the T24 uses a protected setup menu hierarchy.
***Power-On Sequence:** The display is turned on by pressing and holding the **POWER** button for **3 seconds**.
***Protected Menu Access:** To enter the main setup menu, press and hold **UP + POWER** (or **UP + DOWN**) simultaneously within **3 seconds** of system boot-up.
***Factory PIN Security:** Menu entry requires entering the default factory PIN code **1234** using the navigation keys.
***Basic Vehicle Metric Calibration:**
***Unit Selection:** Toggle between **Metric (km/h, km)** and **Imperial (mph, miles)** readout formats.
***Wheel Diameter (Rim Size):** Configurable from **6 inches to 30 inches** to ensure exact speed monitoring and odometer tracking.

Section 3: Riding Modes, Assist Tuning & Cruise Control
Precise Power Modulation & Electronic Assist Rules
The T24 interface allows riders and technicians to fine-tune power delivery rules across both the heavy-duty DM01 and lightweight DM02 drive systems.
***Customizable Assist Levels:** Configurable **LevelCount** parameter allowing between **1 and 8 distinct assist levels** to balance battery efficiency and motor output.
***Integrated Walk Assistance:** Holds a steady **6 km/h walk-boost mode** to assist riders when pushing heavy e-bikes uphill or through rough terrain.
***Reverse & Climbing Gear Parameters:** Advanced submenus support reverse gear speed limits (**3 km/h to 10 km/h**) and specialized climbing assist modes for auto-sensing cadence systems.
***Cruise Control Unlocking:** Features electronic cruise control that maintains road speed without continuous pedal or throttle input. Shipped disabled by default for safety, cruise control can be toggled to **Enable** under the Application menu and activated on the trail using handlebar shortcuts.

Section 5: Motor Calibration, FOC Tuning & Diagnostics
Torque Sensor Zero-Point Calibration & On-Screen Workbench Testing
What truly distinguishes the T24 as a technical workhorse is its ability to perform deep motor controller adjustments and hardware diagnostic tests without requiring external computer software.
***Automatic Startup Torque Zero-Point Calibration:** On torque-sensing ToSeven models, the controller executes a zero-point torque sensor calibration at every startup. The display enforcement rule requires that **no weight or pressure be placed on the pedals during power-on** to ensure smooth, natural power assistance.
***Advanced Torque Sensor Tuning Parameters:**
***Operating Modes:** Select between **Sensitive** mode (activates when net torque voltage exceeds starting threshold) and **Safe** mode (requires both net torque voltage and active pedal movement).
***Voltage Thresholds:** Configurable **ZeroVol** zero-point voltage (**100 mV to 2000 mV**), **MaxVol** output voltage (**1000 mV to 3300 mV**), and **StartupNetVol** net starting voltage (**200 mV to 2000 mV**).
***FOC Vector Control & Flux Weakening Access:** Advanced technician submenus allow adjustments to controller resistance, inductance, current PID loops, and **Flux Weakening current (up to 10A)** for high-speed motor expansion[1][17].
***Built-In Display Diagnostic Test Sequence:**
1. Set the assist mode to **Level 0**.
2. Rapidly short-press **POWER** until **'Test'** appears on screen, then press **UP**.
3. Short-press **POWER** until **'Drive'** appears at the top of the screen.
4. Real-time diagnostic fields will immediately display live feedback for **Throttle voltage, PAS pedal sensors, Motor RPM, Controller temperature, Motor temperature, Hall sensor states**, and **Brake Lever status (OFF when released, ON when squeezed)** to isolate hardware issues instantly.
