Hi

I am new to Mazatrol. I am wondering is there any way to remove all the parameter at a time?

Second, I am facing some parameter problems.
My QT10N(T2)'s M20 OP parameter displayed ***.
I could enter 1 & 0 for M20, however, it returns as ***.
In the order words, I cannot modifty it's value.

Third, I cannot change M28 to M31's values.
I want to make M28-M31 as all 0, but the system don't allow me.
So I could only leave 1 for M28-M31 now. I don't know why...
And when I start the lathe, the alarm 22 NMI Memory Parity lights up.
I have 2 QT10N, and both of them have the above problem. I really hope someone could teach me how to slove this out.
Thank you!!

Don
