Denford Software & Machines

Hi everyone!!!, it's me again, seems like our little denford loves to get us into trouble , now it displays the following messange:

"Alarm 101 P/S"

And i have no idea what does it means, and how to deal with it, can anyone help me out or tell me please how to solve this little inconvenient?, thanx for all your help.

Hi,
Alarm 101 is as follows,

"The power was turned off while rewriting the contents of the memory in the part program storage & editing operation. When this alarm is generated, set the setting data PWE to 1 and turn on the power while pushing the DELET to clear the memory."

You will loose any programs stored in the memory by doing as Martin says but there is little other choice.

Please let us know how you get on.

Good Luck!

I've regularly seen this error occur when the Fanuc control has been turned off whilst waiting for RS232 input (or in the process of RS232 progam download).

I quickly learned you should NEVER turn the Fanuc control off whilst you have LSK or INPUT flashing in the bottom of the screen. Always press the RESET key to quit RS232 mode before turning off the control.

I don't know if this is what has happened in your case but it is always a good 'rule of thumb' to follow anyway.

Saying that, I also remember a number of occasions where I have LSK flashing and the control has 'locked up' so I have no choice but to kill the power and hope I don't get the dreaded PS101 alarm

As Steve says, you've no choice but to do as Martin suggests but you'll loose and CNC programs you had in the Fanucs memory

I've also lost everything by switching off when the RS232 hung up

I found out that pulling the RS232 cable out from the Fanuc would cause the Fanuc to time out - allowing you then to reset.
