Exactly! The brake is there for safety only upon power loss. We too have used this many times. Again, there should be no harm to the motor or drive if it is holding 0 position on it's own.
What SERVOCAM said. Servos give feedback (only position though, velocity is calculated by the drive in most cases), and steppers don't. A stepper motor assumes that it arrived where it was supposed to.
SERVOCAM: We have done similar things on past projects. We ran our cabling through a drum that was mounted to the axis. The drum contained enough cable to accomodate the rotation of the axis, and then was passed through the middle of the table. This worked fine until the cables wore out...
Yes, wireless was and still is being considered, but I don't think it will work. We have to run servo power, which cannot be wireless or inductive. We have to run servo communication, which can be done wireless. To run a wireless network, I need to have power on the rotary unit, hence my...
Hopefully I have the right forum!
I have an application where I need to have a servo motor and some I/O mounted on a rotary weld table, but we don't want to use slip rings. I realize I will need to for motor power and for the welding ground cable, but I don't want to run communication signals...
