Description
F0‑01
Motor 1 control
mode
0: Sensorless
vector control
(SVC)
0
This is open‑loop vector
control applied to high‑
performance control
scenarios. One AC drive can
drive only one motor. It is
used for loads such as
machine tools, centrifuges,
wire drawing machines,
and injection molding
machines.
1: Feedback vector
control (FVC)
This is closed‑loop vector
control. An encoder must
be installed at the motor
end, and the AC drive must
be equipped with a PG card
of the same type as the
encoder. It is applicable to
scenarios requiring high‑
precision speed control or
torque control. One AC
drive can drive only one
motor. It is used for loads
such as high‑speed paper
machines, cranes, and
elevators.
2: Voltage/
frequency (V/f)
control
This is open‑loop speed
control applicable to
scenarios with low
requirements on load
control performance, such
as fans and pumps. If one
AC drive controls multiple
motors, only the V/f control
mode can be used.
5: Open‑loop
speed control of
synchronous
motors (PMVVC)
It is suitable for loads with
low precision
requirements, such as fans
and pumps.
F1‑20
Filter time
constant (for VVC)
0.003 V to 65.535 V 0.100 V
This parameter specifies
the filter time constant in
VVC mode.
F1‑21
Oscillation
suppression gain
(for VVC)
0 to 65535 100
This parameter specifies
oscillation suppression
gain in VVC mode.
