you may want to look for a program lock key, a physical key that is in the wrong position.
I have a Clausing Multiturn CNC2000XS. I need some guidance with the handy screen. We have the tool offsets and parameters locked out so over zealous button pushers can't change things they're not supposed to. When I need to adjust the tool offsets I follow the procedure for making edit. I am in MDI and then in the handy screen I change parameter write from 0 to a 1 and make whatever adjustments and then change parameter write back to 0. Something has happened where I can't change the state of parameter write. When I input a 1 using the hard input key the value never changes. When I use the soft input the parameter never changes thus not allowing me to make any changes to tool offsets. I have tried this with the estops in and out. I have tried doing a power cycle and all with the same result. There are a hand full of people that know how and are allowed to make these changes. I believe someone has accidentally made a change to one of the parameters and then locked the write enable and I don't know what that would be. I appreciate any guidance.

PWE Write Protect Bit
Parameter 3299 bit 7
PK5 The KEYPRM signal (memory protection signal, parameter write
setting) is:
0 : Disabled.
1 : Enabled.
Must be changed in the Offset/Setting page.

PWE Write Protect Bit
Parameter 3299 bit 0
PKY The KEYPRM signal (memory protection signal, parameter write
setting) is:
0 : Disabled.
1 : Enabled.
Must be changed in the Offset/Setting page.
With the parameter write locked will the control allow me to change anything? We have a second machine with similar control. Subtle differences here and there. I tried to compare and make changes to match one to the other and I would get a parameter write message. cincyice58 mentioned the physical key. Would this have to be unlocked as well to change parameter 3299? Bit 0 on this parameter is currently 0. Bit 7 is currently 1

If you go to where you turn on PWE on you can page down to this parameter and change it.
Can you post a picture of the machine and I will speak to 600 who made the machine
Have you tried changing the Parameter write enable to 1 with the emergency stop in
Thanks for the help .I think I got it. I was going from the handy screen and pushing system button to get to 3299. That's where I was going wrong. I scrolled to 3299 and it accepted the change and then I was able to change parameter write in the handy screen. I believe this got changed when one of our maintenance guys changed it instead of bit 6 GOF on 3290. Thanks again.
