Yaskawa drives and servos

Hi group I have finely started to switch my Smithy 3n1 over to CNC using EMC , Has anyone in the group used the Yaskawa drives at all I was told that the drives I have will take a step signal I am now waiting on Yaskawa to see if they have a pin out on there drives to a PC .Still waiting

Yaskawa drives are SGDA-04-AP and the motors are SGMP-04 400watt and 200 volt

I can not wait to get this up and running I think the servos will work out great 180 oz with a peak of 560oz

thanks guys in advance

Say, JJBrew and BigJohnT, did either of you gents come on any examples of a successful implementation of a LinuxCNC system using Yaskawa AC servos? Rooting around in my motor box I just found a pair of motors and drives with nearly identical part numbers to JJBrew's.

I'd appreciate any tips. Thanks in advance.

Well, it turns out there are some Yaskawa servo EMC2 users out there. Maybe I posted my question prematurely--sorry. Some pretty sophisticated discussion exists, e.g.. "That is exactly the case with my Yaskawa / EMC2 servo system. If fact this common setup is called a ' P / PI Cascaded Loop with Velocity Feed Forward'". Guess I'll keep my ears open.
