I can not quantify it, but when the Z axis is joged is a bit delay between the move command and the "click" noise that indicates the brake release and axis starts moving. Is there a parameter that can change that delay? I wired the servo brake following the centroid wiring diagram. Changin...

The z axis servo is a dmm 1.8 kw servo with brake integrated from factory.

Hello all
The problem with the Z axis falling down a few 1/100 mm when the CNC 12 is reset and when the CNC is shut down, remain.
Posted last Februar.
I managed to make a test with no faults.
I am uploading the last report.
Help would be very apreciated.

Hello I Also have a similar problem. Industrial Mill retrofit with Oak board and DMM AC servos. Model Mikron WF-31D with automatic spindle gear box. The spindle motor has 2 speeds (low and high) and then a gearbox that using 3 diferent 24 Vdc motors alloww the diferent spindel speeds. The original c...

Hello I am retrofiting a Mikron WF 31D (table Moves Z and X axis) Head moves Y axis. It is a swiss industrial machine (3,5 ton in total) Since the controler was damaged, I changed the servos to DMM AC servos ( X and Y 1 KW and Z axis 1,8 KW +brake) and OAK board. I am having problems with the Z axis...

Hello, Dear Marthy I am also having the same problem with the OAK+DYN4 Z axis (using a 1,8 KW servo with Brake) Always faulting for feeds over 300mm/min. Similar to the one that you have on the video FADAL TRM - Centroid CNC Oak DMM AC Servo Conversion - Finale'. When you mention that a 100 ohm resi...

Hello After Marthys help; No more encoder diferential or quadrature errors. In did the problem was that the drives had no power when the controler started. Only when the CNC12 was fired up. Since I wired the drives power on the contactors output, according to the inicialy sent by DMM diagramm ( that...

This is the way I wired the Estop.

The Estop only cuts the motor power the drives are always on, once CNC12 is loaded.
