Yes, I have 3ph vfds being controlled by Linuxcnc. On two multi spindle routers. One with 8 spindles and one with 6 spindles. The 8 spindle machine is using MB2hal to control the routers, on/off and set/monitor the speed (AC Tech brand VFDs). The 6 spindle machine is using parallel ports and a cheapo parallel port breakout board to control the spindles and set their speed with analog control (cheapo Huan Yang knockoff VFDs). It actually works to send one analog output to multiple drives.
The other routers I've done only turn the spindles on/off. It would not take much to add the speed control, but never bothered since we really don't mess with the spindle speeds much.

Quick little survey on what everyone has on their machine for spindle control. 1. Do you have a VFD on a 3 phase motor for Lathe or Mill. 2. Does the CNC controller drive the spindle or do you set the speed and ON/OFF manually? Just curious John "ELS! Nothing else works as well for your Lathe" Automation Artisans Inc. www dot autoartisans dot com _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
