Tips: Variable Frequency Drive Overvoltage
Overvoltage alarm is generally present at downtime, the main reason is that the deceleration time is too short or the braking resistor and the braking unit are problematic. For example, a 5hp VFD displays "OU" when shutdown. Before repairing the VFD, should make sure the reason for "OU" alarm is what. Here is because during the VFD deceleration, the speed of the motor rotor winding cutting the rotation magnetic field becomes fast, the rotor electromotive force and current increases, so that the motor is in power generation state. The feedback energy flows to DC part through the diode, which connects in parallel with high-power switch tube in inverting part, and finally causes by DC bus voltage increase. So, should focus on checking the brake circuit. After measuring the discharge resistance, find there's no problem. In the measurement of the brake tube find it breakdown. Replace it and power on, even fast parking have no problem.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
