Yaskawa SGDM fault help needed
Hello,I am in the middle of retrofitting a cnc punch machine with a newer PC based controller system with newer servo motors and drives.I had purchased 2 sets of servos and drives off EBAY that consist of 2 Sigma II SGDM drives and 2 sgmah motors,the drives did not come with any cables.So my problem is when I went to bench test and start tuning my servo sytem with my motion contoller I get a fault as soon both amps power up, and that is AC9.That fault pertains to the absolute encoder not communicating with the drive.So after reading the manual i find out if you unplug,or somehow the battery dies on you, you have to reset the encoder with the "FN008" param.so when I try the resetting procedure,I get a "NO OP" flasshes for a second its not allowing me to reset.Since the system did not came with any encoder cables,I made my own using 6 pin firewire cables because the encoder conn,is basically a firewire conn.I varrified the 3.6 volts,5 volts for the encoder itself is reaching the encoder,and it is.After about 3 hours of rechecking connections and varrifying params,I decided to call Yaskawa tech support,and basically the'ye saying I needed to by 2 of their $160.00 encoder cables.I dont buy it,the cable I made from a firewire cable,is shielded high quality,probably better quality than OEM.So is their anyone came acoss this fault,any help would be GREAT!

Hello, i have the same issue with Yaskawa Drive SGDM-02ADA and A.C9 alarm. I can NOT find out what is the possible fix for this problem. I checked the cables, the connectors and the settings on the driver. I get the same message on FN008 as "tommee10533" says above.
Any help ??
Thanks in Advance

Re: Yaskawa SGDM fault help needed
Guys,
You have a wiring error on your encoder or you have the wrong motor/encoder pair for that particular driver. Check the driver and see if it is compatible with your drive, if so then you can reset the parameters and start setting them again. Watch this video on youtube showing the AC9 error when the encoder is missing or wired incorrectly. You mentioned absolute encoders do you have a battery installed? Not positive but some absolute encoders want the battery present.
