Kavan GO-1222MGW 22g Waterproof Programmable Digital Micro Servo w/ Titanium Gears

Overview

The KAVAN GO-1222MGW (KAV20.1222MGW) is a powerful and fast 22 g programmable digital micro servo with a coreless motor, durable titanium gears, dual ball bearings, and a wide operating voltage range of 4.8–8.4 V. The IP67 water- and dustproof housing makes it particularly suitable for 1:16 off-road RC cars, boats, robots, and smaller RC aircraft, even in demanding conditions.

Programmable functions

• Servo angle: Sets the maximum travel of the servo. The default setting is approximately 120° with a normal control pulse width (900~2100 µs); approximately 180° with the maximum permitted control pulse width (500~2500 µs).
• Servo neutral: Sets the neutral (center) position of the servo.
• Damping factor: Sets the servo's stopping characteristics.
• PWM power: Sets the servo's output power. The higher the value, the faster the servo moves and the more thrust it provides—of course, current consumption will increase proportionally. Range: 39.2~100%
• Sensitivity: Adjusts the servo's sensitivity (deadband). The higher the value, the narrower the deadband—the servo moves only when the change in control-signal width is greater than the deadband. A sensitivity value that is too high may cause servo oscillation in some applications. Range: Ultra High (Extra High—sensitivity deadband approx. 1 µs) - High (High—approx. 2 µs) - Medium (Medium—approx. 3 µs) - Low (Low—approx. 4 µs)
• Soft start: Enables/disables the soft-start function. This function prevents the servo from moving abruptly to its operating position when power is switched on, reducing the risk of damage to the servo gears.
• Reverse: Reverses the servo's direction of rotation.
• FUTABA SR mode: For use only with a FUTABA RC system in SR mode. Do not enable this option when using another FUTABA RC system setting or an RC system from another brand.
• SANWA SSR mode: For use only with a SANWA RC system in SSR mode. Do not enable this option when using another SANWA RC system setting or an RC system from another brand.
• Fail-safe: If the receiver's control signal is completely lost or the servo cannot detect the signal correctly (e.g. due to interference), the servo can enter one of three fail-safe modes:
  • (a) Free: Fail-safe is disabled.
  • (b) Hold position: The servo maintains the position corresponding to the last correctly received signal.
  • (c) Return to neutral: The servo returns to the neutral position (1500 µs pulse width).
• Overload protection: Enables or disables the servo's overload protection at three levels. Once the overload has lasted for a preset time (in seconds), the servo's output power is limited to the corresponding preset value (% of maximum power).
• Reset: Restores the connected servo to its factory settings.
