MACHINE PARAMETERS.
(REF: 1402)
Machine parameters for the axes. Work sets.
COUNTERID
Number of the feedback input for the axis.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drives and velocity-Sercos drives.
Possible values: Remote modules, from 1 to 40 / Sercos drive, from 1 to 32 / Local inputs, from 1 to 2.
Default value: 0.
Associated variable: (V.)[ch].MPA.COUNTERID[set].xn
The feedback input of an analog axis and the input for the external (direct) feedback of a
Sercos axis may be located at the remote modules, at the free feedback input of a Sercos
drive, in an RCS-S module (Sercos counter) or at the local feedback inputs of the central
unit. Depending on the location of the feedback input, this parameter will indicate which
feedback input will be used (either local or remote) or the drive/counter number. When two
axes will not be in the configuration at the same time, the CNC allows using the same
feedback input for both axes.
Feedback input in CANfagor remote modules.
A counter module is used as feedback input in the remote modules. This parameter indicates
the number of the feedback input being used.
The counter modules are numbered following the logic order of the remote groups (rotary
switch of the power supply). If there are several Counter modules in each group, the order
is from top to bottom and from left to right. The counters of the first module will be 1 through
4, those of the second module 5 through 8 and so on.
Feedback input in Sercos drives.
In this case, the second feedback input of the drive will always be used. The parameter
indicates the logic address of the drive (from 1 to 32). The "address" rotary selector switch
sets the logic address.
Feedback input of an RCS-S module.
This parameter indicates the number of the feedback input being used.
The RCS-S modules are numbered according to their logic order (parameter
SERCOUNTID). The feedback inputs of the first module will be 1 through 4, those of the
second module 5 through 8 and so on.
Local feedback input.
The central unit has two feedback inputs. This parameter indicates the feedback input being
used.
SET THE DRIVE ASSOCIATED WITH THE AXES OF A
MULTI-AXIS GROUP.
DRIVESET
Set of the drive to be used.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for a Sercos drive.
Possible values: From 0 to 8.
Default value: 0.
Associated variable: (V.)[ch].MPA.DRIVESET[set].xn
At the axes that belong to a multi-axis group, parameter DRIVESET indicates the set to be
activated at the drive after a set or gear change at the CNC (G112 and M41 to M44). The
CNC sends the changes of Kv, feed-forward (parameter FFGAIN) and AC-forward
(parameter ACFGAIN) to the set indicated in this parameter.
Being parameter matching active, the CNC sends the parameters of set ·1· of the master
axis to the set ·0· and to the gear ·1· (first) of the drive. For the rest of the sets of the master
axis, the CNC only sends the gear data to the drive; set ·2· of the CNC to the gear 2 of the
drive and so on. At the master axis of multi-axis group, in order for parameter matching to
work properly, this parameter must coincide with the set number where it is; i.e. DRIVESET=1
in set ·1·, DRIVESET=2 in ·2· and so on. At the slave axis of a multi-axis group, this parameter
indicates the gear to be used at the drive. If the axis belongs to a multi-axis group, the
parameter does not admit a ·0· (zero) value.
