Hey guys,
I had a question with regards to controlling Servo Motors.
I understand that stream of pulses are sent to the motor , and the width of each pulse determines both direction and speed of the servo.
Questions:
1. Does a servo motor come built in with a circuit that is capable of reading such pulses and translate them to movement? or is a controller required to do so ?
2. I read that these pulses are usually 1-2ms pulse width , and have a pulse interval of approx 18ms.. That means a worse case period of 20ms, which translates to a frequency of 50Hz. Is that the maximum frequency for all Servos ? Does anyone know of companies who sell faster servos?
3. I haven't seen any datasheets of servo motors which state the response time of the motors. i.e: how long it takes the motor to reach the specified position after it accepts the pulse signal sent to it.. I know it depends on the pulse signal you give it, but is there any spec that states the worse case delay?
Any addition info on servos will be very vrey helpful
Thanks guys..
