(2) Inter-axis full-synchronous mode (Pr.7.22, bit 1 = 1)
This mode is used when MINAS-A5N's all internal control process start timings between 2 or more axes are to
be synchronized. Some functions (e.g. analog monitoring) other than operation instructions may also be
synchronized.
• Set the same value to the TMG_CNT for all axes and update the count every 2 ms.
• If TMG_CNT is not counted up correctly, communication is not established (COM_LED is not lit in green) or
inter-axis synchronization is not established.
• The time necessary to establish the communication (COM-LED is lit in green) varies depending on a pair of
axes to be synchronized.
• Even if synchronization is established, inter-axis synchronization will not be established when start-stop
communication error occurs at the start of the operation (especially at the beginning of the PP control mode).
