Hi there,
We’ve got two questions:
1.) We were wondering if there is a command that can be sent to the robot in order to have it’s servos cease working. Basically, we want to replicate the functionality of the “Stop”-Button from the FlowArm PLTW software by sending an appropriate command via the serial interface.
2.) We’ve been trying to read from COM3, however, so far we’re getting nothing. Is there actually no feedback after sending commands?
Thanks for your help!
Hi,
Here are answers to your questions:
You can stop a servo motor by sending it a position command with position zero. For example, if we wanted to stop the servo motor on channel 5 we would send #5P0. This will stop current motion of that servo motor and also cancel the signal being sent to that channel. This means the servo motor will be able to move freely (without resistance / holding a position).
Try sending the following command: VER. You should receive a reply from the SSC-32U containing the firmware version running on it currently. Most commands do not have feedback so do not expect any from them! 
Sincerely,
Hi Sébastien,
Great, many thanks for your fast reply. I shall try doing so first thing on monday
Cheers,
Ercan
