Cycle times in the "Vector U/f" control mode
The following table shows the number of axes that can be operated depending on the
selected cycle times in the "Vector U/f" control mode:

Mixed operation of the "Servo" and "Vector U/f" control modes
In mixed "Servo" with "Vector U/f control" operation, one axis with servo control is considered
to be two axes in U/f control mode.
Table 1- 10
Mixed operation of the "Vector" and "Vector U/f" operating modes
In mixed "Vector" with "Vector U/f control" operation, one axis in vector control is considered
to be two axes in U/f control mode. A maximum of 6 axes are permitted in conjunction with
vector control.
