3. Motor parameter auto-tuning status: If there is any running command after the function code P03.24 is
set as 1 or 2, the drive will enter the motor parameter identifying status. It will enter the stop status after
the parameter identification is completed.
4.2.3 Drive control mode
Control mode
High-performance open-loop flux vector control: refers to the vector control without the speed sensor. The PG
is not installed, but it has high control performance, low frequency high torque and high constant speed
precision. It can realize precise motor speed control.
4.2.4 Drive frequency channel
There are five running modes for the MV200 drive under the speed control mode, including: jog running,
process closed loop running, PLC running, multi-stage speed running and common running. The jog running
has the top priority, other modes low priority. If there is no jog running command, select the mode according to
P02.04 channel. The priority is as shown in Fig.4-9.

Fig. 4-9 Running mode selection
The five running modes provide five basic frequency sources. Except that the auxiliary frequency
superimposition, frequency adjustment can be performed for common running frequency, “jog running”, “PLC
running”, “multi-stage running" or “process closed loop running" can be served as an independent running
channel, among which, “PLC running” has various frequency source reference channel. For details, please
refer to “PLC running” frequency reference selection function code. The running modes are described below:
