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.
PG Speed Control Board
(PG-A2 or PG-D2)
Open-Loop Vector Control (A1-02 = 2)
Open-loop vector control enables the use of high-performance drives without a speed detector. PG (pulse gen-
erator) wiring is not required.
Flux Vector Control (A1-02 = 3) (SPEC: E or Later Only)
Flux vector control 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.
