Description of variable frequency drive
ST310 inverter series is a powerful high-performance current vector inverter, which can realize the
control of the asynchronous motor, V/F control mode, one machine with multiple functions, can realize
multiple frequency switching, and can be used for textile, Drives for automated production equipment
such as papermaking, wIre drawing, machine tools, packaging, and food.
Product Testing of variable frequency drive
Semi-finished product testing
After all semi-finished products are processed, the quality department will carry out a comprehensive
appearance test and electrification test. After the test is completed, professionals will apply three layers
of three-proof paint, and some products will undergo electrification aging test.
All test data are archived to ensure the consistency of product testing. Abnormal test data can be recalled
and investigated later.
The finished product testing
At least 12 hours after the production is completed, the aging temperature is 55 degrees to ensure the reliability
of the internal electronic components.
After the aging is completed, load tests such as loading, impact, rapid acceleration, and deceleration are carried out
with the excitation motor, and the input and output ports of the product are tested to ensure the consistency of product
performance and various functions
