1. To switch the motor of the power frequency, the parking method is set to free parking, and it is important not to park softly
2. The contactor of the motor is blocked from the output end of the frequency converter, and the control stop button and the parking button of the frequency converter are the same composite button, that is, when the parking is pressed, the contactor coil is de-energized and the connection between the motor and the frequency converter is blocked;
3. The contactor of the motor is intercepted from the output end of the inverter, and the control start button is interlocked with the start button of the inverter, that is, the contactor can be started only after the motor is connected;
4. The motor is connected to the contactor of the power frequency, and its coil control loop is controlled by the normally closed contact of the contactor of the motor at the output end of the inverter to ensure that the output end of the inverter is connected to the power frequency after the motor is blocked
5. If the switching process is agile and accurate, that is, the shorter the moment when the motor runs away from the power supply inertia, the less the speed drops, and the less there is "impact", that is, the motor switches under the rated current;
6. Here it is necessary to pay attention to the phase sequence of the motor accessing the power frequency to ensure that the motor is switched to the same direction!
7. An isolation circuit breaker should be set up from power frequency to motor.

Precautions for the operation of Delta servo motors
1) The AC servo motor works by means of a dedicated drive. Do not connect the commercial power supply (100/200V, 50/60Hz) directly to the line of the servo motor, otherwise the servo motor will not work properly and the servo motor will be permanently damaged.

The parameter that needs to be set for the inverter - Delta
There will be some difference between the parameter setting of the inverter at the factory and the requirements of practical application. Therefore, the reasonable setting of the inverter parameters is directly related to whether the inverter can be used normally, which is of decisive significance.
General-purpose inverters generally have dozens or even hundreds of functional parameters.

Introduction to Constant Power and Constant Torque in Frequency Conversion Speed Regulation - Delta
In general, factory motors are based on the additional speed values obtained at a given power frequency voltage (380 V, 50 Hz). If 380V is not reached under actual operating conditions, e.g. as long as 300V, 50 Hz, the voltage is significantly undervoltaged. Fundamentally, it cannot reach the extra rev value, due to the ...
