High torque/very high speed digital low-profile servo with steel gear and double BB-ed output shaft. Works great in 1:10 on-road RC cars (suitable for Modified, Stock, FWD, Formula classes). An aluminium middle part of the servo case for perfect cooling under high load.
MB-2312 is programmable using the KAVAN 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 (900~2100µs); 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 bandwidth. 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 (1500µs 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.
Wide input voltage range 4.8–7.4 V (nominal); operating voltage range 4.8–8.4 V.
