Page 35: 6: Vehicle Performance Adjustment
Return to TOC 6 — VEHICLE PERFORMANCE ADJUSTMENT The 1212/1212P controller’s adjustable parameters allow many aspects of vehicle performance to be optimized. Once a vehicle/motor/controller combination has been tuned, the parameter values can be made standard for that system or vehicle model. Any changes in the motor, the vehicle drive system, or the controller will require that the system be tuned again to provide optimum performance. - Page 36 1212 & 1212P Manual - Sep 2019 Return to TOC Step 6: Setting the acceleration and deceleration rates The acceleration and deceleration functions have been designed to provide smooth throttle response when maneuvering at low speeds and snappy throttle response when traveling at high speeds.

Questions and answers
Здравствуйте! Оборвали провод от кнопки питания как правильно подключить
To properly connect the power button wire for Curtis Instruments part number 1212, connect the keyswitch input (power button) to terminal J1-5 (KSI). This allows power to flow when the button is activated. Ensure a fuse is installed between the battery positive (B+) and J1-5 for protection.
