Control method
IFD – LIFT = Space vector modulation (vectorial modulation PWM with V/f curve)
VTC = Vector Torque Control (Sensorless vectorial, direct torque control)
Frequency/speed setting
resolution
Digital reference: 0.1Hz (IFD SW); 1 rpm (VTC SW)
Analog reference 10bit: 0.01% resolution of maximum output
frequency/speed with respect to max. speed
Speed precision
Open loop: 0.5% of max. speed (2% for IFD SW and LIFT)
Closed loop (with encoder): < 0.5% of max. speed
Overload capacity Up to 2 times rated current for 120sec.
Starting torque Up to 200% Cn for 120sec and 240% Cn for a short duration
CONTROL
Torque boost Programmable for a rated torque increase
Operation method Operation through terminals, keypad, serial communication
