Usage and parameter adjustment
Usage and parameter adjustment
1. The steps of the inverter parameter setting operating instructions are as follows:
1. "Restore factory settings": Restore factory settings after powering on, in order to avoid the existence of some previously set parameters in the inverter (of course, this problem does not exist if it is a brand-new inverter);
2. "Set motor type": whether the motor is an asynchronous motor or a synchronous motor. Of course, it is generally an asynchronous motor, and the default is also an asynchronous motor;
3. "Set the motor parameters according to the motor nameplate": Just check the motor nameplate on the motor body;
4. "Jog operation to confirm whether the direction of motor rotation is correct": During this operation, be sure to pay attention to whether the load carried by the motor interferes or collides with the motor when it is running. During the process of starting the operation, use low-speed operation to test. Can;
5. "Set the inverter to self-learning mode": Some inverters do not support self-learning mode, and the operating parameters of such inverters need to be set one by one. Of course, most of the frequency converters currently on the market support self-learning, which greatly liberates our industrial controllers from complicated parameters;
6. "Start learning and perform motor matching operation": As with the previous inching operation, be sure to pay attention to whether the load can run forward and reverse. At the same time, please note that in self-learning mode, the motor will rotate quickly, so be careful! 7. "After the operation is completed, set the running command channel": Through self-learning, you can quickly set the operating parameters of the inverter. At the same time, it is also necessary to manually set the control command source channel for the operation of the inverter, such as IO terminals, analog ports, network communication, etc.; the inverter supports these control command channels: start and stop (IO terminal) + frequency (internal Setting) start and stop (IO terminal) + frequency (analog port) start and stop (IO terminal) + frequency (network communication) start and stop (network communication) + frequency (internal setting) start and stop (network communication) + frequency ( Network communication) start and stop (network communication) + frequency (analog port)
2. How to use the frequency converter and adjust its parameters
1. In layman’s terms, the operating command of the frequency converter refers to how the frequency converter is started, such as through the frequency converter start key, external terminals, or communication, etc.
2. The frequency source of the frequency converter is given by where does the frequency converter control the motor frequency? It can be the frequency converter panel, the external potentiometer of the frequency converter, or communication, etc.
3. For the motor parameters of the inverter, just enter the corresponding parameters according to the data on the motor nameplate, such as current, power, speed, etc.
4. Drive mode of the frequency converter.

Soft start working principle
Soft start working principle
The soft starter uses three opposite parallel thyristors as a voltage regulator, which is connected between the power supply and the motor stator. This kind of circuit is like a three-phase fully controlled bridge rectifier circuit. When a soft starter is used to start a motor, the output voltage of the thyristor gradually increases and the motor gradually accelerates until the thyristor is fully conductive and the motor operates at the mechanical characteristics of the rated voltage to achieve a smooth start, reduce the starting current and avoid starting overcurrent tripping. When the motor reaches the rated speed, the starting process ends, and the soft starter automatically replaces the thyristor that has completed the task with a bypass contactor to provide the rated voltage for the normal operation of the motor, thereby reducing the heat loss of the thyristor and extending the service life of the soft starter. Improve its working efficiency and avoid harmonic pollution of the power grid. The soft starter also provides a soft stop function. The soft stop process is opposite to the soft start process. The voltage gradually decreases and the speed gradually drops to zero to avoid the torque impact caused by free stop.
