This parameter is used to display the delivered model and cannot be modified.
•
1: Applicable to constant torque load with rated parameters specified
• 2: Applicable to variable torque load (fan and pump) with rated parameters specified

0: Sensorless fl ux vector control (S F VC)
1: Closed-loop vector control (CLVC)
2: Voltage/
F requency (V/ F ) control
0
• 0: Sensorless flux vector control (SFVC)
It indicates open-loop vector control, and is applicable to high-performance control
applications such as machine tool, centrifuge, wire drawing machine and injection
moulding machine. One AC drive can operate only one motor.
• 1: Closed-loop vector control (CLVC)
It is applicable to high-accuracy speed control or torque control applications such as
high-speed paper making machine, crane and elevator. One AC drive can operate only
one motor. An encoder must be installed at the motor side, and a PG card matching the
encoder must be installed at the AC drive side.
• 2: Voltage/Frequency (V/F) control
It is applicable to applications with low load requirements or applications where one AC
drive operates multiple motors, such as fan and pump.
Note
• If vector control is used, motor auto-tuning must be performed because the advantages
of vector control can only be utilized after correct motor parameters are obtained. B etter
performance can be achieved by adjusting speed regulator parameters in group F 2 (or groups
A2, A3, and A4 respectively for motor 2, 3, and 4).
• F or the permanent magnetic synchronous motor (PMSM), the I5300 does not support S F VC.
CLVC is used generally. In some low-power motor applications, you can also use V/ F .
