two parameters are very important to the operation of asynchronous motors, therefore after the
asynchronous motor is first installed, the motor parameter auto tuning must be performed for
functioning correctly.

It is used to set encoder disconnection fault detection time, when it is set to 0.0s, the inverter
does not detect the disconnection fault of encoder.
When the inverter detects a disconnection fault, and the fault lasts for more than b0.34 set
time, the inverter gives out Alarm Err.20. message.

The rotary transformer has pole-pairs, the correct pole-pairs parameters must be set when
using the kind of encoder.

1: restore the factory setting, not including motor parameters:after y0.00 is set to 1, most of
the inverter function parameters are restored to the factory default parameters, but motor
parameters, frequency command decimal point (F0.02), fault recording information, cumulative
running time , cumulative power-on time and cumulative power consumption will not be
restored.
2: clear history:to clear the history of the inverter's fault recording information, cumulative
running time , cumulative power-on time and cumulative power consumption.
3: restore default parameter values including motor parameters.
4: backup current user parameters:backup the parameters set by the current user. Backup all
function parameters. It is easy to restore the default settings when user incorrectly adjust
parameters.
501Restore user backup parameters:Restore previous backup user parameters.
