| SERVO MOTOR PWM Frequency |
| (1/1) |
| NASK:
Hi guys ! I cant understand how to determine PWM frequency for SERVO Motors using datasheet.but this site says https://electrosome.com/servo-motor-pic-microcontroller/ it is 20ms. how to find it Hitec HS-425BB and VIGOR VS-10A SERVOs. Hitec HS-425BB VIGOR VS-10A |

Hobby servos like those generally accept a 50hz input, with a pulse width between 1 and 2ms. As it says there, Centre is 1.5ms |
| MarkR42:
Frequency isn't what drives servos, it's the width of the (positive) pulse. The space between pulses, i.e. frequency, isn't important at all. Most servos keep trying to do the same thing until they receive another pulse, but eventually turn off after some delay (e.g. 100ms). This is completely typical with a 1500us pulse for "centre" position. |
