8. TANDEM DRIVE
2) Operation example for normal mode
a) Start operation method
1. Set the home position return method (parameter No.0240) to scale home position signal
detection method and tandem drive option (parameter No.0265) to normal mode.
2. Set the tandem drive home position signal offset (parameter No.026C, 026D).
3. Start home position return operation.

Note 1. When a limit switch signal is detected, an alarm occurs and execution of return to home position is terminated.
2. Set the distance between the master axis/slave axis home position signals and the start operation position so that it is
greater than the deviation at maximum tolerance of the master axis and slave axis.
