8. TANDEM DRIVE
POINT
Synchronization is validated after home position return complete (after home
position is established). When the home position return request (ZREQ) is
ON, synchronization is not performed.
ON, synchronization is not performed.
Set the speed at synchronization using the tandem drive synchronous
alignment speed (parameter No.0267) and the speed units multiplication
factor (parameter No.020E, 020F).
factor (parameter No.020E, 020F).
When start operation is performed during synchronization, the tandem drive
while performing synchronization (operation alarm 55, detail 01) occurs.
When drive mode is toggled during synchronization, the tandem drive mode
change error (operation alarm 50, detail 01) occurs.
If the "tandem drive synchronous alignment valid width error" (operation alarm
54, detail 01) or the "tandem drive synchronous alignment error" (operation
alarm 58, detail 01) occurs within absolute position detection system, the
absolute value will be lost.
(The absolute position data of the home position return option 2 (parameter
No.0241) becomes invalid and "absolute position erased signal" (ABSE) turns
on.)

absolute value will be lost.
(The absolute position data of the home position return option 2 (parameter
No.0241) becomes invalid and "absolute position erased signal" (ABSE) turns

Implement a stop command on the master axis. Because system is in
synchronous mode, a stop command to the slave axis is invalid.
If the synchronization setting (parameter No.0265) is set to invalid,
synchronization for turning servo on is not performed. The position board
operates with the deviation between the master axis and the slave axis held.
The setting of this parameter becomes valid at the leading edge of servo
ready (RDY) signal.
While synchronization is invalid, the following operations may make a
deviation between the master axis and the slave axis. As necessary, perform
synchronization (micro-adjustment) with the user program. In addition, check
the deviation between the master axis and the slave axis is within an
allowance.

The servos can be turned on and off separately. Movement is as the same as normal axes.

8.6 Tandem drive axis limit switch
If the limit switches on either the master axis or the slave axis is detected, an alarm occurs and both axes are
stopped using the rapid stop time constant. For other types of movement, normal axis movement is followed.
