8. TANDEM DRIVE
2) Operation example for adjustment mode
a) Start operation method
1. Adjust the axis linking the master axis and slave axis mechanically at a right angle to the
movement direction.
2. Set the home position return method (parameter No.0240) to scale home position signal
detection method and tandem drive option (parameter No.0265) to adjustment mode.
3. Start home position return operation.
4. After home position return is complete, read the tandem drive home position signal offset
(parameter No.026C, 026D) and save it to the user program.

greater than the deviation at maximum tolerance of the master axis and slave axis.
