A0.07
Model selection
Range:0～1
Default: 0
0: Motor 1
To use motor and control parameter of motor 1
1: Motor 2
To use motor and control parameter of motor 2
A0.08
Motor control mode
Range:00～22
Default:01
Unit’s place: Motor 1 control mode
0: V/f control
Constant voltage&frequency 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, we need to set
related parameters of Group d1 carefully.
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 parameters Group d0 and d1.
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.
Ten’s place: Motor 2 control mode
0: V/f control
Constant voltage&frequency 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 2 under V/f control is selected, we need to set
related parameters Group d4 carefully.
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 parameters Group d3 and d4.
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 d5

Range:0～1
Default: 0
0: Digital 0utput terminal 2
1: Pulse output
A0.12
PWM optimization
Range:000～123
Default:000
Unit's place: PWM modulation mode
0: Fixed carrier
Carrier of inverter is a fixed value set by A0.13.
1: Random carrier
Inverter carrier will vary with output frequency in linear variation. Upper/Lower carrier frequencies
are under control of A0.14 and A0.15.
2: Derating of fixed carrier
Inverter can adjust carrier value based on A0.12, carrier temperature and carrier current,
protecting itself against over temperature.
3: Derating of random carrier
Inverter can adjust carrier value based on random carrier, carrier temperature and carrier current,
protecting itself against over temperature.
