I have got this E252 alarm (tool in toolchangerarm).
Its not possible to do a toolchange with M6, but if i do a M66 (manual change) and then a M6 directly after the ATC will work once.
Any suggestions to fix this?
I have tried the I/O recovery of toolchanger but too no help.
Hi, this just says there is a tool in the tool gripper, depending on the version of machine, you may have a proximity switch on the gripper giving you an incorrect status. Check and see if there are any proximity switches on the tool changer monitoring the grippers and let me know.
Cheers

Hello ,
I am also getting this error E252 tool in toolgripper alarm ( DMU 60T - Millplus 1999 model)
After loading parameters & BIOS in battery problem.
No sensor in tool gripper. Checked all PLC IOs , its ok.
I think somewhere system memory, gripper has to be reset.
Please guide for this problem.

Hi, Have you found the solution to this problem? I have the same problem.
ANY SOLUTION I HAVE THE SAME PROBLEM
I managed to solve the E252 error.
I turned the machine on and press delete.
Then heidenhain numeric service menu appeared.
From there i selected 6. Load default machine constants and clear all memories.
After I needed to import all machine parameters.
