1. AXIS CONTROL
99
The DI/DO signals, generally connected to each axis, must be connected
only to the master axis of two axes of tandem control. The signals need
not be connected to the slave axis. The following signals, however, may
have to be connected depending on the application.
i) Controlled axis detach signal and servo off signal
Connect these signals so that the master and slave axis signals are
simultaneously input.
ii) Overtravel limit signal
Connect the signal so that 1 is always output as the overtravel limit
signal for the slave axis.
If the slave axis stroke limit must also be detected, connect the signals so
that the signal detected on the slave axis is sent to the overtravel limit
signal of the master axis.
Connect the motors according to the servo axis numbers. Connect the
feedback cable of the slave axis.

Motor overload and other servo alarms are displayed separately for the
master and slave axes.
The parameters that are generally set for each axis can, when set for axes
under tandem control, be classified into the following three groups:
i) Parameters in which identical values must be set for the master and
slave axes
ii) Parameters that must be specified only for the master axis (The
corresponding parameter for the slave axis is not used.)
iii)Parameters for which different values may be set for the master and
slave axes
