Optimised Drive Characteristics
Advanced flux vector control
The original flux vector control developed
by MITSUBISHI ELECTRIC offers new per
-
formance characteristics in drive tech-
nology.
High torque (150 %) at very low
frequencies (1 Hz)
By combining slip compensation and flux
vector control MITSUBISHI ELECTRIC has
achieved a loaded torque of 150 % at a
frequency of 1 Hz. Due to the integrated
auto-tuning function the flux vector con
-
trol is even provided for widely varying
motor characteristics.
The figures compare rational speed/load
torque characteristics and rational
speed/motor current for general purpose
flux vector control and V/F control
(motor 0.75 kW).
Inrush current limiter
Allinvertersareequippedwithaninrush
current limiter providing a protection of
the connected components.
