I am using a Micro Maestro 6-Channel USB Servo Controller (Assembled) and would like to power on and power off the servo motor after a setting position. I have set the communication to USB dual port and connected the LabVIEW command to com TTL. After using the command protocol below.
it still did not work.
Has anyone tried doing that on a Micro Maestro 6-Channel USB Servo Controller (Assembled) for powering on and off the servo motor? Must the processor be powered for this case or only servo is required?
Thank you in advance for any helpful suggestion.
The picture you posted is from the documentation for our older micro serial servo controller, so any serial commands documented in there will not work with the newer Maestros, like the Micro Maestro you are using. You can learn more about serial communication with the Maestro inside the “Serial Interface” section of the Maestro’s user’s guide, which you can find under the Resources tab of its product page. You might also consider getting started with this LabVIEW VI for the Micro Maestro, which was made by one of our customers. (However, please note that we do not use LabVIEW, so we do not know how well it works.)
The Maestros get processor power from the computer when connected over USB, so you do not need to separately connect power to the board in order for it to generate servo signals. (The servos still need to be powered, however, for them to respond to the servo signals.)
Setting the target to 0 on a Maestro will cause it to stop sending pulses to the servo. Most servos will stop trying to maintain their position if this happens. If you need more control over connecting/disconnecting power to your servo, you might consider adding an RC switch with a relay or MOSFET, which can be triggered with servo pulses generated by the Maestro.
