4. MULTIAXIS SYNCHRONIZATION
(Power Mate i–H)
To perform synchronous operation, follow the procedure below.
1 Set axes related to a synchronous operation.
Make parameter settings such as a relationship between the parent axis
and child axis, and axis attributes.
2 By using NC statements or a ladder, create commands for the
3 Execute the program created in step 2.
A multiaxis synchronous operation is performed with the
synchronization relationship set in step 1 and the operation pattern
created in step 2.
Two types of synchronization are available. One type moves the local axis
in phase with the motion of the parent axis. The other type starts
synchronization of the local axis with the parent axis when the parent axis
reaches a specified position.
The former is called mechanical synchronization control, because the
parent and child axes can be considered to be mechanically connected
with each other.
The latter is called start point synchronization control, because a
synchronization start point is specified.
Synchronous operation can be performed with an NC command or PMC
Before performing synchronous operation, turn on the synchronous
signal operation mode and select the synchronous mode in advance.
When using an NC command, be sure to perform synchronous operation
in the state where G91 is specified for incremental command.
The synchronous operation commands G145 and G146 described later
belong to G code group 05 (to which G94 and G95 also belong).
These commands are modal. So, when performing synchronous
operation, turn on the synchronization mode signal then specify G145 or
When performing feed per minute or feed per revolution, however, turn
off the synchronous mode signal then specify G94 or G95.
