Digital servo (CAN or Sercos)
The bits of identifier 33172 "FagorDiagnostics" contain the following information:
Cyclic channel. Write variables for the CNC-PLC
PLC parameters SWR800 (P68) through SWR819 (P87) indicate which type of information has
been put in registers R800 through R819 and which drive will be assigned that value.
These parameters are set in 1.5 format. The units digit identifies the drive (node) supplying the data
and the decimals indicate the identifier number (see table below).
For example, "P70=2.34178" indicates that the value of PLC register R802 will be assigned to the
"DigitalOutputsValues" of the drive located in bus node 2.
The type of information available and its associated identifiers are:
The "VelocityCommand" variable can be modified for the axes that have been selected as DRO axes,
by axis parameter DROAXIS (P4) or via PLC by activating the logic CNC axis input "DRO1,2,3,..."
Service channel
The service channel can only be accessed through a high-level block of a part-program, a PLC
channel or a user channel. All variables can be accessed except the string type appearing in the
drive manual.
