*1 TSN hub is required for star topology.
*2 An error will not occur even if there is no station and axis in the network setting.
*3 Even if the station is a multi-axis drive unit device (a device which can control two axes or more), the number of station is counted as one
station when it is recognized as one station. For details, refer to each drive unit instruction manual.
*4 When a slave emulate is carried out, the number of stations is counted according to the connected device setting.
SD memory card
The specifications of the SD memory card is shown below.
Item
