Some questions regarding a servo motor's data sheet.

[selbstdual]

Have a look at the attached file.

How do you interpret the paragraph starting with 8 and 9.

Re 8: Does it mean that within 1,1ms and 1,9ms the motor should be able to rotate _somewhere_ in between 34° and 50° or does that mean that 1,1ms equals 34° and 1,9ms equals 50° or vv?

Re 9: Does that mean that you should not let the pulse be shorter than 1ms and longer than 2,2ms?

Awesome answers. Especially by electronic-"experts".

Way to go to have some answer huh?

Stupid.........?

Not a stupid question, but your second post "Awesome answers. Especially by electronic-"experts"" is only few hours after your first one, and it's tone is a bit arrogant... well to me.

Sorry, i don't have a clue of servo motor, and i have no plan to use them, unless a customer ask. If so, i'll buy one and do some test, and read the datasheet to understand what it mean.

Sure there's some servo user here... probably they just sleep when you posted your thread?

Sometime i ask question here... and sometime nobody answer them... have it told everyone thanks for not replying?

Be patient...

Hi, Steve

We do not sleep ...

Just remember some previous posts ...

That's all

For a pulse width of 1.5ms the servo has a max angluar travel of 42 degree (+/- 0.4ms gives 8 degree)

The max pulse width is 1.6ms (+/- 0.6)

I must admit that it seems strange having a max value that has a +/- value as well. I should be worded max pulse width 1.6ms with an "absolute" max pulse width of 2.2ms

To give you some camparison, normal RC model servos used an accepted "standard" of 1ms - 2ms with 1.5ms representing centre position. Most RC servos tend to give 45 degrees either side of centre, ergo 0 degree = 1ms - 90 degree = 2ms, so I would equate that to your servo as 42 degree for 1.5ms is near enough to a "standard" servo.
