CONTROLLING SERVO MOTOR BY A M BHATT

[query]

now I have some doubt on controlling of servo motors

if I give pulses of 1.5 ms at 50 hz then motor will move to position 90 deg.

now if i want to take it back to 0 deg position then will it work if I supply 1 ms pulse at 50 hz.

is there any need to continuously supply pulses for retaining position.

what if pulses are stopped?

dude servo motor works on PWM…so for a standard servo,

1ms @50 hz – 0 degree

1.5ms @50 hz – 90 degrees

2ms @50 hz – 180 degrees

 

if u give 1.5ms @50 hz thn it wil mov to 90 degrees position and if u apply to it 1ms pulse @ 50 hz thtn it will again go to 0 degrees
