GO-1280MG (0.085s/60°, 40kg.cm)

Very high torque/high speed programmable digital standard 79g brushless servo with hardened steel gear and triple BB-ed output shaft. Works great in 1:8 or 1:10 off-road RC cars etc. All-aluminium waterproof and dustproof case (meeting IP67 standard requirements) for perfect cooling under high load and protection from the rough environment. The magnetic encoder instead of the regular mechanical potentiometer adds to the uncompromised precision and reliability.

GO-1280MG is programmable using the KAVAN GO servo USB programmer/interface and PC software.

Programmable Functions

• Servo Angle: Maximal servo rotation angle range setting. The default range is ca 120° within the regular RC signal pulse width range (900~2100 µs); ca 180° within the max. signal pulse width range (500~2500 µs).
• Servo Neutral: Servo neutral (centre) position setting.
• Damping Factor: Servo damping setting – adjust the characteristics of the servo when stopping.
• PWM Power: Adjusts the servo output power. The higher the power, the higher the speed and torque of the servo – indeed also the current consumption will be higher.
• Sensitivity: Servo sensitivity (Dead Band) setting. The higher sensitivity the narrower the dead band – servo moves only if the change of the signal pulse width is bigger than the dead band width. Too high setting may cause servo jitter in some applications. Range: Ultra High (ca 1 µs dead band) – High (ca 2 µs) – Medium (ca 3 µs) – Low (ca 4 µs)
• Soft Start: Turns on/off the soft start feature. If ON, the servo goes slowly to the initial position corresponding to the servo signal once the power is switched on.
• Reverse: Reverses the servo movement direction.
• Narrow Band: FUTABA SR Mode – only for use with FUTABA radio channels working in the SR mode. Do not turn the option on if you are using a different setting of your FUTABA radio or any other radio.
• SANWA SSR: SANWA SSR Mode - only for use with SANWA radio channels working in the SSR mode. Do not turn the option on if you are using a different setting of your SANWA radio or any other radio.
• Lost PPM Protection (Fail-Safe): In the case the control signal from the receiver is lost completely or cannot be decoded correctly (due to interference) the servo can use choose one of three fail-safe modes:
• (a) Release: No fail-safe protection.
• (b) Keep Position: Keeps the position corresponding to the last correct control signal.
• (c) Go Neutral Position: The servo returns to the neutral (1500 µs pulse width) position.
• Over Load protection: Enables or disables overload protection of the servo in three levels – once the overload conditions last for the pre-set time (in seconds), the output power of the servo is reduced to the corresponding pre-set level (% of the max. power).
• Default: Restores the factory default setting of the connected servo.
