performance. This value should be set as the motor rated slip frequency, which can be
calculated as below:
P4.09=fb-n*p/60
Where fb is the motor rated frequency, corresponding to P2.01, n is the motor rated speed,
corresponding to P2.02, and p is number of pole pairs of motor.

AVR function is the auto-voltage-regulation function of output voltage. When AVR function
is invalid, the output voltage changes as the input voltage (or DC bus voltage) changes; when
AVR function is valid, the output voltage does not change as the input voltage (or DC bus
voltage) does, and it basically keep constant within the output capacity range.

During the motor operation with no load or light load, by means of detecting the loading
current, appropriately regulate output voltage to save energy automatically.
Important: this function is especially effective for loadings like blower and pump.

When the operation command path is terminal control, during the inverter powers on, the
system inspects the status of operation terminal.
0: Terminal operation command invalid when power on. During power on, even if the operation
command terminal is inspected valid, the inverter will not run, the system stays in
operation-protection state, till this operation command terminal is cancelled, and then, active
this terminal, the inverter will run.
1: Terminal operation command valid when power on. During power on, if the operation
command terminal is inspected valid, the system will start the inverter after initialization.
Important: User should select this function carefully, or it could cause serious result.
