6.2 Detailed Description on Function Parameters
F0 Series Basic Operation Parameters
F0.00 Control Mode Setting Setting Range: 0~1 Factory Default Setting: 1
This function is used to select the inverter's control mode.
0: Open-ring Vector Control
This is also called "SVC", indicating no speed sensor vector control, which is
applicable to high performance speed regulation without installing an encoder.
1: V/F Control
This is applicable to the speed regulation where there are no high requirements for the
speed control precision, low frequency torque and other performances, and can be
used when several motors are driven by an inverter.
Tips
If vector control mode is selected, it is necessary to learn the
motor parameters before the first operation to get the exact
motor parameters. Be sure the nameplate data of the motor
conforms to the motor parameters of the inverter before self-
study. Otherwise, self-study can not be accomplished or error
results will be turned out. If the nameplate data of the motor
can not be received, then V/F control mode is suggested.
If vector control mode is selected, be sure to set proper
parameters (F1.14, F1.15) for speed regulator to ensure a good
stability and dynamic performance.
If vector control mode is selected, one inverter can drive
only one motor and there is not too much gap between the
inverter capacity and the motor capacity. Otherwise, the
control performance may fall or the machine can not run
normally.
