Connection of Cable and Driver
Connect motor power cable and signal cable with the corresponding interfaces of driver
according to the definition in cable sleeve.(Note: The low level output of the limiting sensor is
normally closed output mode.)
Note:
All wiring is in the state of power-off, and the power can be debugged after
inspection.

Fiber Input Interface
BM111 is suitable for most industrial fiber lasers. It is equipped with collimating lens assembly.
The connection between the end of the fiber and the cutting head is called fiber interface.
Commonly used fiber connectors include QBH, QD and so on, and every fiber interface has its
unique fixation method. Please refer to corresponding instruction of fiber interface. Figure 5 shows
the installation interface of QBH connector.
Note:
The optical devices must be kept clean and all dust must be removed before use. If
the optical fiber is vertically inserted in the laser head, the laser head must be rotated 90
degrees to the horizontal level and then inserted the optical fiber in it to prevent dust
from entering the interface and falling on the surface of the lens. Insert the optical fiber before
fixing the laser head.
