4.3 Machine parameter setting
The tandem control is defined with the following axis machine
parameters.
These parameters are located in the parameter table of the master
axis. The slave axis does not have an axis table at the CNC, although
it is possible to access the parameter and variable tables of the slave
axis drive. It is accessed from the machine parameters > drive.
TANSLAID (P76) TANdem SLAveID
Sercos identifier ID of the tandem slave axis. This parameter of the
master axis of the tandem selects the axis that will generate the
velocity command for the slave axis.
This parameter enables all the other parameters of the tandem. If this
parameter is zero, there is no tandem axis and it ignores the values
of the rest of the tandem control parameters.
TANSLANA (P77) TANdem SLAve NAme
Slave axis of the tandem.
This parameter is used in the following cases:
• To identify the marks of the slave axis DRENA*, SPENA*,
DRSTAF* and DRSTAS*. To refer to these marks, it is
recommended to use as indexes the letters X-C (e.g. DRENAX,
SPENAZ). Numerical indexes (e.g. DRENA1, SPENA2) follow a
special criteria; they are the ones following the rest of non-slave
axes.
• Identify at the CNC the errors of the tandem slave axis.
• Identify the parameter tables of the tandem slave axis drive.
TORQDIST (P78) TORQue DISTribution
Torque distribution. It indicates the torque supplied by each motor in
order to obtain the necessary total torque on the tandem axis.
This parameter refers to the master axis. It is defined as the
percentage of the total torque demanded from the master axis. The
difference between the value of this parameter and the 100% is the
percentage that will be applied to the slave axis.
If the motors are identical and they're both supposed to output the
same torque, this parameter should be set to 50%.
This parameter can be modified from the oscilloscope and from the
PLC.
0 None 1 - X axis 2 - Y axis 3 - Z axis 4 - U axis
5 - V axis 6 - W axis 7 - A axis 8 - B axis 9 - C axis
By default: 0
Possible values: from 0 to 100%.
By default: 50%
