Megmeet MV300 Series - Drive Control and Running Mode Settings; Drive Frequency and Torque Channels

62
The command channel can be selected through function code P02.02, the PANEL/REMOTE key on the
operation panel, and the multi-functional input terminals (functions No. 38, 39 and 40 are selected through
P09.00~P09.05).
 Note
Before switching the channels, be sure to conduct the switching trial operation first, otherwise, equipment
damage or human injury may be caused.
4.2.2 Operating status of the drive
The operating states of the MV300 include the stop status, running status and motor parameter auto-tuning
status.
1. Stop status: If there is no running command input when the drive is started and initialized, or the stop
command is executed during the operation, the drive will enter the stop status immediately.
2. Running status: The drive will enter the running status after receiving the running command.
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 MV300 drive has 2 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. 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.
Running mode
There are two running modes for the MV300 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 MV300 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 MV300 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.
