‹ Control Methods and Applications
Application examples for the MxC control methods are provided below.
„ V/f Control (A1-02 = 0)
V/f Control is suitable for applications that require the motors to operate at variable speeds.
Fig 10.1
„ Open Loop Vector Control (A1-02 = 2)
Open Loop Vector Control enables high-performance functions without a motor encoder. PG (pulse generator)
wiring is therefore not required.
Fig 10.2
„ Flux Vector Control (A1-02 = 3)
Flux Vector Control is suitable for applications high-precision functions that require PG feedback. High-preci-
sion positioning, zero-speed control, and torque control are possible with this mode.
