72 Function Parameter Table
6.8Vector control parameter group
F7.00 Control mode selection
Setting range: 0~1
This parameter is used to select control mode:
0: V/F control
1: SVC (open loop vector) control
F7.01~ F7.05 Motor rated parameter
Setting range: ——
To guarantee the control performance, please refer to AC
asynchronous motor nameplate parameters:
1） Set the nameplate parameters correctly.
2）Motor and inverter power should match with each other. Generally,
inverter is only allowed to drive 2-level smaller or 1-level larger motor.
Once rated frequency (F7.01) changed, following parameters will be
matched automatically, please modify them in order.
F7.06~ F7.08 Motor internal parameter
Setting rangte: ——
This group of parameter will be automatically updated after
parameter identification, users have no need to set it.
F7.09~ F7.13 Reserve
F7.14 Pre-excitation time
Setting range: 0~3.0S
This parameter group is used to define pre-excitation time before
motor start.
It needs a certain amount of time (approximately equal to the rotor
time constant) to form AC asynchronous motor air-gap flux. When motor
is under stop state before starting, air-gap flux must be formed in advance
to obtain a sufficient start torque.
