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 and running mode
Control mode
The MV600 drive has 4 control modes, which are set by the function code P02.00.
1. Vector control without PG: 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 torque control and speed control. It is generally used in the
applications with high robustness requirement which the V/F control mode cannot satisfy.
2. Vector control with PG: PG needs to be installed. To ensure the control performance, the PG needs to
be installed on the controlled motor shaft. It is used in the applications with faster torque response and
higher torque and speed control precision. Additionally, with PG as the feedback, it can realize the
position control (i.e. servo control function).
3. V/F control without PG: It is used in the ordinary applications in which there is no high performance
requirement or the applications in which a single drive controls several motors.
4. V/F control with PG: PG needs to be installed, which can increase the V/F speed control precision.
Running mode
There are two running modes for the MV600 drive vector control:
1. Speed control: To precisely control the motor speed, for which the related function codes of Group P05
shall be set.
2. Torque control: To precisely control the motor torque, for which the related function codes of Group P06
shall be set.
The MV600 drive supports the online switch of the above running modes.
4.2.4 Drive frequency and torque channel
1. Frequency reference channel under speed control mode
There are five running modes for the MV600 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.
