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