After the expansion is installed, P1-25 should be set correctly according to the actual situation, otherwise the
inverter may not operate normally.

Set the pulse per rotation of ABZ incremental encoder.
In the vector control mode with speed sensor, the encoder pulse number must be set correctly, otherwise the
motor will not run normally.

The function code is only valid for ABZ incremental encoder, that is, only valid when P1-25 = 0. It is used to set
the phase sequence of AB signal of ABZ incremental encoder.
The function code is effective for asynchronous motor. When the asynchronous motor is tuned dynamically, the
AB phase sequence of ABZ encoder can be obtained.

The resolver encoder has the logarithm. When using this encoder, the pole logarithm parameter must be set
correctly.

Speed feedback PG disconnection
detection time
0.0~10.0 (0.0: Speed feedback disconnection
detection invalid)
It is used to set the detection time of encoder disconnection fault. When it is set to 0.0s, the frequency converter
will not detect encoder disconnection fault. When the frequency converter detects the disconnection fault and
the duration exceeds the set time of P1-33, the frequency converter will give an alarm.

Motor parameter self learning
Ones bit:
0: No operation
1: Static self learning 1 (part of parameters)
2: Motor rotation self-learning
3: Static self learning 2 (part of parameters)
Tens bit:
0: Synchronous motor
1: Asynchronous motor
Generally speaking, the effect of dynamic tuning is better than that of static tuning. It is suggested to choose
dynamic tuning, but dynamic tuning should separate the load from the motor. If it is difficult to separate the load
from the motor, only static tuning can be selected. Both static tuning and dynamic tuning are only effective in
vector mode, that is, when P0-01 is set to 1 or 2.
Tuning steps of vector control without speed sensor mode(Take asynchronous motor as an example):
