2000 Series 5-Turn, Dual Mode Servo (25-3, Speed)


Meet the Dual Mode 5-Turn ‘SPEED’ Servo. Like the other 2000 Series goBILDA® servos, the 2000-0025-0503 boasts two different modes:

Default Mode

In Default Mode the servo is able to rotate while having positioning feedback. In this mode, the PWM signal will determine the position of the servo. 

Continuous Rotation Mode

Using the 3102 Series Dual Mode Servo Programmer (1-1) the servo can be toggled into continuous rotation mode.  In this mode, the servo will have proportional speed control based on the PWM signal that you send with your servo controller.

How Far Will This Servo Rotate in Default Mode?

The answer to this question is partially dependent on what you are using to control the servo.

With an Average Radio System:
2.25 Turns (810°)
Your average transmitter and receiver will output a relatively narrow PWM signal range.

Radio System + Travel Tuner:
5 Turns (1800°)
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
5 Turns (1800°)
The Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
