Mixed operation of servo control and U/f open-loop control
In mixed operation with servo control and U/f control, one axis in servo control at 125 µs
uses exactly as much computing performance as two axes in U/f control at 500 µs. In
conjunction with servo control, a maximum of 11 axes are permitted (1 servo plus 10 vector
U/f).
Table 1- 9
Mixed operation of vector control and U/f open-loop control
In mixed operation with vector control and U/f control, one axis in vector control at 250 µs
uses exactly as much computing performance as two axes in U/f control at 500 µs. In
conjunction with vector control, a maximum of 11 axes are permitted (1 vector plus 10 U/f).
