V/f Control without PG (A1-02 = 0)
V/f control without a PG is suitable for applications where multiple motors are operated with a single Drive, such
as with multi-motor drives.
Fig 10.1
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.
Fig 10.2
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) wir-
ing 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-precision
positioning, zero-speed control, and torque control are possible with this mode.
