combination of power and multiple-function.
Dynamic torque-vector control promises
optimum motor control under any operating conditions.
1. Dynamic torque-vector control
Dynamic torque-vector control system
performs high-speed calculation to determine
the required motor power for the load
status. Our key technology is optimal
control of voltage and current vectors for
maximum output torque.
● A high starting torque of 200% at 0.5Hz.*
* 180% for 40HP or larger models.
● Achieves smooth acceleration/
deceleration in the shortest time for the
load condition.
● Using a high-speed CPU quickly
responds to an abrupt load change,
detects the regenerated power to control
the deceleration time. This automatic
decerelation function greatly reduces the
inverter tripping.
● Feedback control with PG
Enables the inverter to execute “vector
control with PG” by adding an optional PG
feedback card to obtain higher performance.
• Speed control range : 1:1200
• Speed control accuracy : 0.02%
• Speed control response : 40Hz
2. Reduced motor wow
at low speed
● Motor wow at low speed (1Hz) reduced to
less than 1/2 of that achieved by
conventional inverters, with the dynamic
torque-vector control system, in
combination with the Fuji’s unique digital
AVR.
