V/f Control with PG (A1-02 = 1)
V/f control with a PG enables precise control of machine line speed. Speed control using the speed feedback
of the machine shaft is possible in this mode.

Flux Vector Control (A1-02 = 2 or 4)
Flux vector control enables the use of high-performance drives without a speed detector. PG (pulse generator)
wiring is not required.
Fig 10.3
Vector Control with PG (A1-02 = 3)
Vector control with a PG is suitable for applications using high-precision drives with PG feedback. High-pre-
cision positioning, zero-speed control, and torque control are possible with this mode.
