Parameter description
When changing motor rated power (P1-01) or the motor rated voltage (P1-02), the inverter will
automatically modify the parameter value P1-06 ~ P1-10, and make these five parameters back to the
usual standard Y series motor parameters.
If the site induction motor can not be tuned, you may according to the parameters provided by the
manufacturer of the motor, input the corresponding function code.
Encoder line number
P1-27
Setting range
Setting ABZ encoder pulses per revolution.
In the case of speed sensorless vector control mode, you must set the correct number of encoder
pulses, or the motor will not operate properly.
Encoder type
P1-28
Setting
range
VFD supports multiple encoder types. Different encoders require matching different PG cards.
Please choose the right PG card to use.
After installing the PG card, properly set P1-28 according to the actual situation, or the inverter
may not operate properly.
ABZ incremental encoder AB phase sequence
P1-30
Setting
range
This function code is only valid for the ABZ incremental encoder, which is only valid when P1-28 =
0. For setting phase sequence ABZ incremental encoder AB signal.
Pole-pairs number of rotary transformer
P1-34
Setting range
Resolver is the number of pole pairs in the use of such an encoder, you must set the parameters
number of pole pairs correctly.
Speed feedback PG disconnection detection time
P1-36
Setting range
It is used to establish encoder disconnection fault detection time, when set to 0.0s, the inverter will
not detect encoder disconnection fault.
When the inverter detects a disconnection fault, and lasts longer than P1-36 set time, the inverter
alarm ERR20.
Tuning Selection
P1-37
Setting
range
0: No action, which prohibits tuning.
1: Asynchronous machine static tuning for induction motor and the load is not easy to disengage, but not a
complete tuning occasion. Before conducting asynchronous static tuning, you must set the correct motor
type and motor nameplate P1-00 ~ P1-05. Asynchronous machine static tuning, the inverter can be obtained
P1-06 ~ P1-08 three parameters. Action description: Set the function code is 1, then press the RUN key, the
inverter will conduct static tuning.
