error 465, dyna dm2016

[kmelektro]

My dyna 4M CNC version 2.21 1999/2 shows some error.

first i can see

"testing drive board",

after this

E465: No response from driver .

A machine doesn't respond to any command, what I shall do to solve the problem ?

Is the Emergency light flashing on the keyboard? It's just below the Reset button. If it is, most likely is the Emergency stop button has been pushed or there is a stuck limit switch.

Thank you for your help, the problem has already been solved but occured a new one.

After I've replaced old engines and encoders, I have a problem with two axis not being able to be based. ( axis with replaced items)

axis go to a basis point ( and normally should move back by 2 milimeters ) and then it slowly moves back to a limit switch.

In the screen I can see already done distance of for example 800 mm and it rises until reaching a limit switch ( normally it never goes more than 300 mm)

can anyone help me with this ?
