8. TANDEM DRIVE
The in-position signal (INP) is output for each axis separately; therefore, when the axes have come to a
stop and in-position signals are being used, check the in-position signal for both the master axis and the
slave axis.
For other types of movement, normal axis movement is followed. (Refer to Section 5.4)
The following shows an example where start operation is performed for the linear interpolation group 1 from
the configuration example on the previous page.

POINT
For Linear interpolation operation, the XA axis and YA1 axis (master axis) are
used for linear interpolation operation.
The YA2 axis (slave axis) moves synchronously with the master axis.
(2) Non-synchronous micro-adjustment mode
Linear interpolation operation cannot be entered while in non-synchronous micro-adjustment mode. The
while in tandem drive non-synchronous mode (operation alarm 51, detail 01) occurs upon start of operation.
