8. TANDEM DRIVE
8.4.2 JOG operation during tandem drive
(1) Synchronous mode
When JOG operation is performed while in synchronous mode, master axis data and signals are used.
An example is shown below.

Important data classifications related to JOG operation during synchronous mode are shown in the
following table. For other related data, refer to Section 10.6.
Type
Items for which only item associated
with master is valid
Items defined for each axis
Command signal/data JOG operation mode (JOG)
Movement direction (DIR)

Deceleration time constant
None
Status signal In JOG operation mode (JO)
During operation (OP)
During smoothing of stopping (SMZ)
In-position (INP)
Position switch (PSW)
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 (INP) for both the master axis and
the slave axis.
For other types of movement, normal axis movement is followed. (Refer to Section 5.1)
(2) Non-synchronous micro-adjustment mode
Movement is the same as for normal axis movement. (Refer to Section 5.1)
