This section lists the performance specifications of the RD78G(H).
Real drive axis
Virtual drive axis
Virtual linked axis
Flash ROM write count
Number of occupied I/O points
Internal current consumption
(5 V DC)
*1 Even when an axis (real axis, and virtual axis) does not exist in the system setting, an error does not occur. Since there is no axis to be
controlled, the motion control cannot be carried out. Operation other than the motion control, such as program execution by ST
language is available.
*2 When a multi-axis drive unit and a general output device are used as multiple axes, the number of those axes are counted.
Ex: The 2-axis drive unit is counted as 2 axes.
*3 It depends on the number of controlled axes.
*4 It is restricted by the system memory capacity.
Total 1024 axes
125 to 4 ms
1- to 4-axis linear interpolation
