8.1.13 Vector control
The motor operates at the vector control mode in which high precision control of speed and torque is provided with
the encoder option card mounted on the main body of the inverter.

Caution
For high performance operation of the vector control mode, correct data should be input on the
related functions including the motor parameter measurement and encoder and so on. Follow the
setting order below before vector control operation. For high-performance control of sensorless(I)
vector control, the inverter capacity should be equal to that of the motor. If the motor capacity is
lower than the inverter capacity by more than 2 phases, there might be a problem with the control
characteristic, so change the control mode to V/F control. In addition, in case of vector control
operation, do not connect more than one motor to the inverter output.
