Setup
Introduction to machine parameters
The machine parameters relate the CNC to the particular machine. The values that the CNC assigns
to each one of them by default are described in the relevant chapter. See chapter "6 Machine
parameters".
These values, shown in the parameter tables, may be modified manually from the CNC’s keyboard
or from a peripheral (pendrive, computer, etc.) via the two serial communication ports RS 232C and
USB.
Some characters appear next to certain parameters indicating when the CNC assumes the new
value assigned to that parameter.
// It is necessary to press the keystroke sequence: "Shift - Reset" or turn the CNC off and
back on.
/ Just press Reset.
The rest of the parameters (those unmarked) will be updated automatically, only by
changing them.
Setting of the machine parameters for the axes
Once the active axes have been assigned by means of general parameters "AXIS1" (P0) thru
"AXIS8" (P7), the CNC will enable the relevant axes parameter tables.
The values to be assigned to the parameters of each of these tables will depend on the results
obtained when adjusting each machine axis.
Before making this adjustment, position the axes near the middle of their travel and place the hard
stops (monitored by the electrical cabinet) near these mid-travel points in order to prevent any
possible damage to the machine.
Verify that the PLC Mark "LATCHM" is OFF. Then, after selecting the parameters of the desired axes,
go on to adjusting them following these advises:
• Adjust the axes one by one.
• Connect the power output of the drive corresponding to the axis being adjusted.
• Selecting the Jog mode at the CNC, jog the axis to be adjusted.
In case of runaway, the CNC will display the relevant following error and the machine parameter
labeled LOOPCHG (corresponding to the sign of the velocity command output of the CNC) will
have to be changed.
• If the axis does not run away; but the direction of the move is not the desired one, axis parameters
labeled AXISCHG (P13) (axis feedback counting direction) and LOOPCHG (P26) (sign of the
velocity command output) will have to be changed.
