Mazak T32-3 tripping out with E-Stop alarm

Hi guys

I have an old Mazak Megaturn vertical lathe with a T32-3 control. It is now tripping out with an E-Stop alarm when the X axis is moving. I have checked the diagnostic page for more info on the cause but it only shows an E-Stop alarm, no other info. I have been keeping an eye on the load monitor and its not spiking over 14% load so normal.
Would anyone have any ideas what to check for here?

Hi,

Look at the servo for x axis. You must see on this controller a alarm number. Controller before them shows 56, controller behind them E7.

Hi there

We have checked the drive units. The X axis has alarm 43 on it, the other drives have E7. I have checked our drive manual and they show error codes up to 37, then it skips to 45. There is no description for 43.
Any help here would be much appreciated.
Regards
Jake
