30.2 Multiple-axis Synchronization Control
Refer to "Multiple-Axis Synchronization Control Specifications Manual" (BNP-C3072-339) for details on parameter settings,
operations, etc.
30.2.1 Outline
Multiple-axis synchronization control is the function that enables multiple slave axes to be synchronized with commands to the
master axis. This function can be used, for example, in multi-head machine configurations.
The axis that serves as the reference of synchronization is called "master axis", whereas the axis that follows the master axis
is called "slave axis".
 The synchronized axes are controlled with travel commands to the master axis.
 For one master axis, two or more slave axes can be set.
 Up to three combinations of master axis and slave axis can be set for all the part systems.
[Configuration example of multiple-axis synchronization control]
The "compensation" in the figure refers collectively to the pitch error compensation, thermal expansion compensation,
backlash compensation, and external machine coordinate compensation. Even under the multiple-axis synchronization
control, the compensation is performed independently for each axis.
Perform position alignment for the master axis and each slave axis at the setup of the machine.
Also, position alignment between synchronous axes is required when power is turned ON. Perform automatic or manual
reference position return, and start synchronous operation after and performing position alignment.
Refer to "22 Setting the Position Detection System" for more details on position alignment.
30.2.2 Synchronous Operation and Independent Operation
Independent operation is unavailable for multiple-axis synchronization control.
Make sure to include the master axis when configuring the setting of "synchronous control operation method" signal.
 Synchronous operation
This method allows both master and slave axes to move synchronously by the movement commands to the master axis.
This method is valid in both automatic and manual operations.
The synchronous operation is selected and cancelled when all axis components are in commanded positions.
 Independent operation
This is unavailable for multiple-axis synchronization control.
