join servo signal wires

[Rushmoore]

Hi,

I have two servos and want them to move at the same time. would it work if i join the two signal wires together and just feed them the same piece of code?

Thanks

This should work, provided the output of the servo driver can supply enough current to drive two servos simultaneously. Give it a try, the risk is very low.

Awesome! Thank you for your help

I very much doubt that you will have success if these are PID positioning loop servo's, each has to have its own control loop.
In a motion control system it is done with electronic gearing, but this also requires individual drives.
It can be done with stepper motors.
What trajectory controller are you using?

I was thinking along the line of RC model servos.

@Rushmoore what kind of servos do you use? This will help us clarify the correct answer.

When he mentioned applying code I assumed regular motion servo's, if they are fed open loop velocity mode it could work, but the relative rpm/position between them will be unpredictable.

... and I assumed code for generating a PWM signal to control RC servos.
So it goes if one makes assumptions
