It is used to set the detection time of the encoder disconnection fault. When set to 0.0s,
the inverter does not detect the encoder disconnection fault. When the inverter detects a
disconnection fault and the duration exceeds the set time of P1-36, the inverter alarms

Default

:
No operation, ie tuning is prohibited.
1: Static tuning, suitable for asynchronous motors and where the load is not easy to
disengage and cannot be fully tuned.
Asynchronous machine static tuning (P1-00~P1-05 must be set correctly) can get
three parameters P1-06~P1-08.
Action Description: Set the function code to 1, then press the RUN button, the inverter
will perform static tuning.
2: Complete tuning To ensure the dynamic control performance of the frequency
converter, please select the full tuning.
Before the asynchronous machine is fully tuned, the motor must be disconnected from
the load to keep the motor in no-load state. The parameters P1-00~P1-05 must be
correctly set. (The encoder pulse number P1-27 must be set under the closed-loop
control with PG card. ).
The inverter can obtain five motor parameters P1-06~P1-10, AB phase sequence P1-
30 (with PG card) of the encoder, and vector control current loop PI parameters P2-
13~P2-16.
Action Description: Set the function code to 2, then press the RUN button, the inverter
will perform a complete tuning.
3: Applicable to the case of no encoder, self-learning of the motor parameters under
the static state of the motor (the motor may still have slight jitter at this time, need to
pay attention to safety)
Action description: Set the function code to 3, then press RUN key, the inverter will
perform no-load tuning. Note: Tuning supports motor tuning in keyboard operation
mode, terminal mode and communication mode.
