groups d0~d2.
1: Motor 2
Selects the current loaded motor as motor 2. Set the parameters of motor 1 in parameter
groups d3~d5. The current loaded motor can also be selected through digital input terminal
"motor 1/2 switchover" as shown in Table 6-1:

control technique
0: V/f control
Constant Volt/Hertz ratio control: Applicable to such cases in which the performance
requirement to the drive is not rigorous, or using one drive to drive several motors, or it is
difficult to identify motor parameters correctly, etc. When motor 1 under V/f control is selected,
need to set related parameters group d1 well.
1: Sensor-less vector control 1
This helps achieve high-performance control without encoder and provides strong
adaptability of load. Under this selection, please correctly set motor parameters of Group d0
and vector control parameters of Group d2. Sensor-less vector control 1 is robust vector
control. If motor rotary autotuning is not able to be performed or permitted, sensor-less vector
control 1 performance would be relatively ideal than sensor-less vector control 2.
2: Sensor-less vector control 2
This helps achieve high-performance control without encoder. This control technique is
superior to sensor-less vector control 1. Under this selection, please correctly set motor
parameters of Group d0 and vector control parameters of Group d2. Sensor-less vector
control 2 is precise vector control and it requires motor rotary autotuning.
Tens place: motor 2 control technique
0: V/f control
Constant Volt/Hertz ratio control: Applicable to such cases in which the performance
requirement to the drive is not rigorous, or using one drive to drive several motors, or it is
difficult to identify motor parameters correctly, etc. When motor 1 under V/f control is selected,
need to set related parameters group d4 well.
