8. TANDEM DRIVE
8.4 Tandem drive axis operation
POINT
Only have the master axis call the start operation functions of each axis when
in synchronous mode.
8.4.1 Home position return during tandem drive
Methods for returning to home position while using tandem drive axes include: dog method, dog cradle method,
data set method, Z-phase detection method, scale home position signal detection method, and scale home
position signal detection method 2. These home position return methods are performed while in synchronous
mode.
Note 1. If a non-compatible method is used to perform home position return, the tandem drive axis setting error (operation alarm 52,
detail 01) occurs when home position return is started.
2. When in non-synchronous micro-adjustment mode, the while in tandem drive non-synchronous mode (operation alarm 51,
detail 01) occurs when home position return is started.
POINT
If a non-compatible method is used to perform home position return, the
tandem drive axis setting error (operation alarm 52, detail 01) occurs when
home position return is started.
When in non-synchronous micro-adjustment mode, the while in tandem drive
non-synchronous mode (operation alarm 51, detail 01) occurs when home
position return is started.
The amount of home position shift is set using a control parameter No.0248,
0249. The home position can be shifted by setting the amount of home
position shift.
If the balance between tandem drive axes is not good just after turning on the
power, it can cause stress to the equipment, therefore use non-synchronous
micro-adjustment mode to adjust the balance and perform home position
return.
When home position return is completed, the home position coordinates
(master axis parameter No.0246, 0247) are set to the current command
position for both the master axis and the slave axis.
