Setting
Description
1: Restore to factory
default
After setting P0210.F=1, most of the frequency converter parameters
are restored to the factory default. But the P0201.F (frequency
converter model), fault record information, running time (r0010), and
some factory parameters are not restored.
2: Restore to factory
default, excluding
motor parameters
After setting P0210.F=2, most of the frequency converter parameters
are restored to the factory default. But the P0201.F (frequency
converter model), motor parameters, fault record information, running
time (r0010), and some factory parameters are not restored.

Function code
Description
Application scenarios
P0203.F:
frequency
converter control
mode selection
Set it to 0: vector
control without sensor
(PG) feedback.
Open loop vector
control mode
It is suitable for general high performance
control scenarios, such as machine tools
(CNC), centrifuges, wire drawing machines,
injection molding machines and other loads.
Set it to 1: vector
control with sensor
(PG) feedback
Closed loop vector
control mode
The motor must be equipped with an encoder,
and the frequency converter must be equipped
with an encoder expansion board of the same
type as the motor encoder. It is suitable for high
precision speed control or torque control
scenarios. One frequency converter can only
drive one motor.
Set it to 2: V/f control
without sensor (PG)
feedback
It is suitable for scenarios where the
requirement of the load accuracy is not high, or
one frequency converter drives multiple
motors. For example, fan and pump
applications.
5.5 Start and Stop Commands
Frequency converter control commands include: start, stop, forward, reverse, jog, etc. It is
mainly set by the following parameter function codes. These parameter function codes are all
interconnected. The start/stop command source can be set to any bit connector, including
operation panel, terminal, communication, etc.
