8055 CNC CONFIGURATION
SOFT: V02.2X
Central unit
Remote hard disk.
The Ethernet connection may be used to use a PC directory (server) as a hard disk. This memory
space may be shared by several CNC's or each may have its own memory space.
The interface and the softkeys of the CNC will the same as if it were a local hard disk. When accessing
the CNC through WinDNC or FTP, the remote hard disk behaves like a local hard disk.
The remote hard disk is configured by machine parameters. The PC that makes its hard disk (server)
public must be connected to the local network.
COM1 - Digital servo (CAN or Sercos)
The digital servo drive system (CAN or Sercos) is located at the COM1 port. This servo system is
enabled through its corresponding software option.
Two types of digital servo system may be used to communicate with Fagor servo drives:
• Sercos interface IEC1491.
• CAN field bus and standard CanOpen communication protocol. Their characteristics, in general,
are similar to those of a Sercos ring with lower transmission speed.
A system may have digital axes (CAN or Sercos) and analog axes together. On the other hand, it
is not possible to have digital axes with Sercos interface and CAN interface at the same time.
Digital CAN servo
Module identification at the bus.
Each one of the elements integrated into the CAN bus is identified by the 16-position rotary switch
(0-15) "Address" (also referred to as "Node_Select"). This rotary switch selects the address (node)
occupied by each element integrated in the bus.
Although the switch has 16 positions, only positions 1 through 8 are valid. The CNC does not have
a switch, The drives occupy consecutive positions (recommended) starting from ·1·.
The corresponding drive must be turned off and back on (or press the Reset button) for the address
change to be assumed.
The NFS protocol is used to communicate with the remote hard disk. This protocol must be available
at the PC that is used as server.
