Synchronization Mode and Communi-
cations Cycle
M1-series Inverters support the following synchronization modes.
• Free-Run Mode
Note
SM Event Mode is not supported.
3-6-1
Free-Run Mode
You can use the Free-Run Mode when synchronization such as the DC Mode is not required.
In Free-Run Mode, slaves perform I/O processing, i.e. refresh I/O data asynchronously with the com-
munications cycle of the master.
Communications Cycle
The communications cycle is determined by the cycle time of the master.
Setting range: 125 μs to 100 ms
