Note:
The ten digit of P0-03 is the motor type selection, and the one digit is the con-
trol mode;
Tens place: 1: synchronous motor, 0: asynchronous motor;
Ones place: 1: SVC, 2: VF, 3: Closed loop vector (reserved)
Œ
The motor type is set to synchronous motor and the control mode is SVC, that
is, P0-03=11.

Set P4-01~P4-06 according to the actual motor parameters.
7.2 Parameter identification
Œ

Ž

Connect the motor, if there is a load, set P4-00 to 1; if it is an empty shaft, set
P4-00 to 2, the digital tube will display TUNE, in order to ensure the control
effect, the motor is best to be no-load and set P4 -00 is 2.
Press the RUN key to perform parameter identification, and wait for TUNE to
disappear, then the parameter identification ends.
The identification process lasts for about 1 minute, and you can press the
STOP button in the middle to exit. During this period, current will be sent, run
the motor at the set acceleration and deceleration time to 60% of the rated
frequency of the motor to observe whether the motor runs smoothly, if not,
press STOP to exit, reach 60% of the rated frequency of the motor, and dece-
lerate to stop after a period of time.
After parameter identification, check whether the parameters of P4-17~ P4-20
are normal.
7.3 No-load test run
Œ

Set the speed to a smaller range, such as P0-11= 20Hz.
Press the run key to check whether the motor can accelerate to the set frequ-
ency and whether the motor current is small. If the motor can accelerate to
the set frequency and the motor current is small, the inverter is basically no-
rmal. Set the frequency to the rated frequency of the motor and check wheth-
er the motor can accelerate to the set frequency.
