8. TANDEM DRIVE
8.2 Parameter settings
8.2.1 Designation of tandem drive axes
Setting the group number in the tandem drive group (parameter No.0264) defines the tandem drive axis. The 2
axes that are set to the same group No. can be driven in parallel. The maximum number of groups that can be
driven in parallel is 8 (groups 1 to 8). Of the 2 axes that are designated with the same tandem drive group
number the axis with the smaller axis number is the master axis and the axis with the larger axis number is the
slave axis.
Control cycle Valid group number
0.88ms 1 to 8
0.44ms 1 to 8
0.22ms 1 to 4
POINT
For the following conditions, upon system startup, the tandem drive axis
setting value error (operation alarm 52, detail 02) occurs, and tandem drive
control can not be performed.
If the complement axis is not set up
If 3 or more axes are set up with the same group number
If the group number exceeds the valid group number
8.2.2 Servo parameters
Set the servo parameters to the same values for the axes for which tandem drive is performed. However, the
rotation direction selection (servo parameter No.110D) can be different values depending on mechanical
specifications.
8.2.3 Control parameters
The settings of the control parameters for when using tandem drive can be selected from among the following
3 selections: "only values of master axis are valid", "set master/slave axes to same values", and "master and
slave can be set separately". Only master axis values are valid means that the parameter settings of the
master axis are used for both the master and the slave. In this case, the parameters of the slave axis are
ignored. Refer to Chapter 11 for setting classifications of each control parameter.
