motor side, and a PG card matching the encoder must be installed at the AC drive side.
‡
2: V/F control
It is applicable to applications with low load requirements or applications where one AC
drive operates multiple motors, such as fan and pump.
Note
If vector control is used, motor auto-tuning must be performed because the advantages of vector
control can only be utilized after correct motor parameters are obtained. Better performance can
be achieved by adjusting speed regulator parameters in group F2 (or group A2 for motor 2).
