Note: please set these codes according to motor nameplate parameters.
CHV series inverter provides parameter autotune function. Accurate parameter autotune
comes from correct setting of motor nameplate parameters.
In order to ensure the control performances, please do the motor setting based on the
inverter standard adaptive motor. If the motor rated power has a too big difference to the
standard adaptive motor, the inveter control performances will be deteriorated distinctly.
Note: resetting of motor rated power (P2.05) can initialize motor parameter
P2.06-P2.10.

After the motor autotune is normally ended, P2.06-P2.10 setting values are automatically
replaced. These parameters are the basis of high performance control and have direct effect
on the control performance.
