Current detection compensation for setting inverter control
,
if it is set too large which
may cause performance degradation.
The parameter is only valid to synchronous motors control, and it is valid to ABZ
incremental encoder, UVW incremental encoder, rotational transformer, wire-saving UVW
encoder, while invalid to sine and cosine encoders.
The parameter can used for obtaining parameters when performing synchronous motor
parameters still auto tunning and synchronous motor parameters comprehensive auto tunning,
and it is very important to the operation of asynchronous motors, therefore after the
asynchronous motor is first installed, the motor parameter auto tunning must be performed
for functioning correctly.

The function code is only valid to ABZ incremental encoder, that is valid only when
b0.28 = 0. It is used to set the AB signal phase sequence of ABZ incremental encoder.
The function codes are valid for asynchronous motors and synchronous motors, when
preforming asynchronous motor parameters comprehensive auto tunning or synchronous
motor parameters comprehensive auto tunning, the AB phase sequence of ABZ incremental
encoder can be obtained.

The two parameters are valid only for synchronous motor with UVW encoder.
The two parameters can used for obtaining parameters when performing synchronous
motor parameters still auto tunning and synchronous motor parameters comprehensive auto
tunning, and the two parameters are very important to the operation of asynchronous motors,
therefore after the asynchronous motor is first installed, the motor parameter auto tunning
must be performed for functioning correctly.

0.1s to 10.0s
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.
