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. Whenmotor 1 under V/f control is selected,
need to set related parameters Group P31 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
P30 and vector control parameters of Group P32.
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 P30 and vector control parameters of Group P32.

 ATTENTION:
 When vector control mode is selected, it is necessary to perform motor parameter
identification in order to obtain correct motor parameters before initial running. Upon
the completion of normal process of motor parameter identification, automatically
acquired motor parameters will be stored into drive for control operation during running.
 It should be noted when vector control is selected that one drive can only be used to
drive one motor. The capacity gap between the drive and the motor should not be
excessively big. Added to this, the power of motor could be two classes lower or one
class higher than its matching drive. Failure to comply will be most likely to result in
performance degradation or abnormal working.
