8.5 Changing of parameter range of an axis (G112)
The CNC may have up to 4 sets of parameters for each axis to define
different dynamic characteristics (acceleration, gains, etc.) for each of
them.
The parameter set may be selected by program using function G112.
This function does not carry out any physical change on the machine
(gear change), it only assumes the parameters of the active set.
When using Sercos axes, function G112 also involves changing the
drive's velocity gear.
Programming
Changing the parameter range of the axes.
To assume a different set of parameter, program G112 and then the
axes and the new parameter set to be selected for each one of them.
Changing the parameter set for the spindle.
In this case, changing the parameter set will be used when working
in positioning mode (M19). When working in speed mode (M03/M04),
function G112 will only change the parameter set; it is NOT the same
as functions M41 through M44 because it does not make a physical
gear change.
When making a gear change using M41 through M44, it is not
necessary to program G112.
Properties of the function
Function G112 is modal.
After validating the machine parameters, every time a program is
executed from the automatic mode, on power-up, after executing an
M02 or M30, after an EMERGENCY or a RESET, the CNC acts as
follows depending on the value assigned to machine parameter
"DEFAULTSET".
If DEFAULTSET is other than 0, it maintains the range defined by
G112. Otherwise, it assumes the range defined by machine
parameter DEFAULTSET.
