17744(0x4550): Lag Position Errors

Cause: Position error (The difference between the NC commanded position and the axis actual position) is too large for a certain amount of time. 

Remedy : If you are getting this error on a new machine, you can try tuning the axis or setting up appropriate lag position parameters. If this error is showing up on an existing machine, you can check the lag parameters to make sure they are not changed. Is maintenance needed to reduce friction in mechanics? Making sure axis can move physically and nothing is blocking it. 

17510 (0x4466) : Invalid IO data for more than n subsequent NC cycles

Cause: NC is not communicating with the drive for n NC Cycles 

Remedy : The error is probably fieldbus related. Has anyone performed anything on the machine, which would cause loose cable connections? Is there any excessive noise that would cause CRC errors? Also, make sure data cables are shielded properly. 

18000 (0x4650): Drive Hardware Not Ready

Cause: The drive is enabled and starting up, however it doesn't have sufficient conditions to function (no error present). During the machine operation, probably something went wrong. 

Remedy: Check to see if the 'status ready' flag is checked for the axis when the all enabling are set. If it is not checked even though axis is enabled, you can try troubleshooting the issue on the drive level
