RDC6685U(-DFM) Control System manual

 Back Position X1Y1/X2Y2: The origin (the relative origin) and the machine’s absolute

origin can be selected. This parameter decides the parking position of X1Y1 or X2Y2’s laser head

after each work.

 Backlash X1/X2: The X1 or X2 axes’ backlash, accurate to 1um.

 Backlash Y1/Y2: The Y1 or Y2 axes’ backlash, accurate to 1um.

 Z1/Z2 Work Speed: It is used to set the split speed of Z axis when the two heads

move mutually.

 U1/U2 Work Speed: It is used to set the feeding speed.

（6）Appropriative parameters

 Double axis origin spacing: when it is a double beam, it refers to the spacing when

two Y-axes are docked at their respective origin points; when it is a double cantilever, it refers

to the spacing when both X-axes are docked at their respective origin.

 Safety distance between two axes: when it is a double beam, it refers to the distance

between two Y-axes moving in the same direction until the collision occurs; when it is a double

cantilever, it refers to the distance between two X-axes moving in the same direction to the

time of collision
