Newbie Baldor servomotor questions

[markaren1]

Hi All,

I have a Baldor FlexDrive (about 10 yrs old) along with a Baldor BSM50N-375AA motor which I want to configure so that the motor will rotate 360 degrees when following the output from an optical shaft encoder that can produces 1024 pulses per revolution.

In the setup software (Flex, V1.09) there are 3 available operation modes - current mode, velocity mode and pulse following, can someone explain the meaning of each.

I have run the desktop control software using COM1 connecting the PC to the controller, and the controller attached to the motor's resolver.

With the motor disabled, I see 65536 (actually +-32k) counts per rotation of the motor (by hand), does that sound reasonable ?

Flex appears to be a 16 bit app. Are there any known issues running this using XP ?

Also, are there any well written tutorials that I might benefit from reading ? The whole world of industrial servo control is quite new to me and I keep tripping up over terminology issues.

Many thanks,

Mark

Normally most systems multiply the basic encoder count x4 so I would have expected to see 4096 p/rev, unless they do more multiplication in the drive?
That looks like x64.
Normally torque mode is used for closed loop positioning and velocity for open loop.
The pulse mode sounds like step/direction such as is used by Mach s/w for e.g.
There is probably a wealth of info here on the web concerning servo etc that can be got by googling.

Many thanks, all working now.

Turned out +-32k is correct for the older Flex Drive.
