Mixed operation of servo control and U/f control
In mixed operation with servo control and U/f control, one axis in servo control at 125 µs uses
exactly as much computing power as two axes in U/f control at 500 µs. A maximum of 11 axes
are permitted in conjunction with the servo control, where 1 axis can be operated in servo
control and 10 axes in U/f control.
Table 14-18 Number of axes for mixed servo control operation
Mixed operation of vector control and U/f control
In mixed operation with vector control and U/f control, one axis in vector control at 250 µs uses
exactly as much computing power as two axes in U/f control at 500 µs. A maximum of 11 axes
are permitted in conjunction with the vector control, where 1 axis can be operated in vector
control and 10 axes in U/f control.
