[Emc-users] Syncronize speed of 5 VFD using MESA and EMC.

2011-12-25 Thread himanshu bhatt
Hello, I am working on Box packing machine,. it has 2 axis (Step/Dir) and 5 ACIM motors with Encoder and VFD. and 30 input outputs. i am planning to use EMC with Mesa cards. Mesa 5i20 + 7I48 6 channel Analog servo interface. My VFDs can take 0-10v .. i just need to syncronize their speed only.
