[Emc-users] Sorbel pwm drives vmd 48/60
guy's just a long shot but has anyone have details of these drives i have 2 to modify , they are slightly different than the manual i ihave as the have a backplane connnector , and i want to find the pwm input thanks Dave -- Slashdot TV.

[Emc-users] VFS11 modbus
Hello! I'm trying to connect my Toshiba VFD to LinuxCNC http://linuxcnc.org/docs/html/drivers/VFS11.html I made the interface according to Michael's diagram. But there's no response from the VFD on pin 3, I checked it with my O-scope. Though there's a signal on pin 5 when I try to connect with Toshiba program. Should I set some parameters on the VFD to see it answering? Thanks! -- Andrew -- Slashdot TV. Video for Nerds.

If not, looks like an interface issue Assuming it works - by default the VFS11 interface is in Toshiba inverter protocol mode You need to set it to Modbus mode with the Toshiba utility or through the panel, only then you can talk modbus to it. While at it, set serial rate to 19200, it's the maximum the VFS11 supports. -m Thanks! -- Andrew -- Slashdot TV. Video for Nerds.

If not, looks like an interface issue I can not, that's the problem. I don't see any signal on the VFD's output pin 3, so it doesn't seem like my interface problem... more like VFD's problem? The question is should there always be some signal on pin 3 or it appears only after we start sending something to pin 5? Though I don't see anything either. -- Andrew -- Slashdot TV.

Re: [Emc-users] VFS11 modbus
I am trying to use Modbus to talk to a card vi TCP which I built myself. I work as a software developer but are not familiar with the protocol, do anyone which registers or what it is called are used for what?

[Emc-users] Possible Trajectory Problem
I've experienced some behavior that might be a bug. The relevant information can be found at: http://www.mattshaver.com/gas/ Running the CAP.TAP program results in the motion depicted in Screenshot.png. Adding a G61 or G64 P0.005 to the program produces a trajectory that closely follows the expected path. Significantly slowing the feedrate also produces normal results. Is this a bug, or is it simply default G64 behavior on a machine configured as this one is? Any comments would be welcome! Thanks, Matt -- Slashdot TV. Video for Nerds.
