ABB introduces new universal mechanical frequency converter

The innovative features of ABB's new universal mechanical drive ACS350 – including FlashDrop technology, sequential programming, flexible user interfaces and cabinet-compatible hardware – help minimize installation and commissioning time. This low-voltage inverter is rated for power up to 7.5 kW.

In the overall profitability of mass production, the average production time per unit is a critical factor. ABB's new generation of general purpose mechanical frequency converters are designed for a range of OEMs and system integrators designed to reduce machine manufacturing or assembly time.

Parameter setting with FlashDrop

ABB's patented FlashDrop technology makes parameter selection and setup easy, as easy as TV remote control. With the handheld FlashDrop unit, important parameters can be downloaded to the drive quickly and safely. The unit can store several parameter sets. For the sake of convenience, each set of parameter sets can be named to clearly indicate the relevant end user or application. A particularly useful feature is the parameter setting that can be done without the drive being powered up – there is virtually no need to unpack the drive. For dealers, the frequency converter can be easily pre-configured prior to delivery and helps OEMs with large production volumes to simplify the commissioning process.

FlashDrop enables customization of the menu structure. You can set parameters, hide parameters, and change the appearance of the menu to complete setup and configuration faster. It also allows the user to easily copy parameters between the drives – just upload to FlashDrop and download to another drive. The unit can be connected to a PC for additional storage capacity, or a parameter set can be created or edited using a PC interface. FlashDrop is fast, easy to use and requires no special knowledge.

Sequential programming

Sequential programming is a standard feature of the new frequency converter, providing a straight-through way to create preset operating sequences without any drive options. For many basic applications, the motor is controlled with signals from sensors and limit switches that are sufficient for use. This helps reduce external PLC capacity requirements, enabling less complex motor control systems and lowering costs.

In this new general-purpose mechanical frequency converter, the user interface is another feature that gives users greater flexibility and the possibility of reducing costs. The control panel is really used when debugging or troubleshooting, so the control panel is not included in the standard configuration. Users who need a control panel can choose one of two types: basic control panel and assistant control panel. Both control panels are detachable, so end users can purchase a control panel and rotate it on multiple drives.

Compact hardware

The new frequency converter has built-in EMC filters and brake choppers, so the equipment is very complete. At the same time, it is extremely compact: in this product category, the 400 V frequency converter with a rated power of 0.75 kW is the smallest. Throughout the series, height and depth are uniform – only the width increases with increasing power – which facilitates installation. Route the cable ducts straight and drill all the screw holes in a straight line.
