Hitachi has developed a powerful new suite of software, called DriveManager, that is designed to enable the remote programming and operation of Hitachi frequency inverters and sensorless flux vector Variable speed drives. The first of the programs within the DriveManager portfolio is called DOP Plus and has been announced in the UK by Hitachi inverter partner HID Limited. The new software runs on any IBM-compatible PC within Windows 95 or 3.11.

Essentially, the software emulates Hitachi inverter existing DOP and DRW hand held programming units, but with the convenience of being able to program Hitachi inverter drives at a desktop with a full size monitor. The screens within the software have been arranged to provide users with the interactivity and intuitive operation of the Windows environment, but also give on screen views of all the DOP screens available. From the toolbar users can load data, select printing, text saving and writing EEPROM data to disk. Because the programming is in text files, the system is ideal for new users of Hitachi inverter drives since there is no need to have access to or knowledge of Hitachi inverter address codes. There are in-built help screens for all function parameters and an automatic quick function parameter selection facility.

The software is able to identify by automatic detection, the Hitachi inverter range being programmed and can also save and load the Hitachi inverter set up to disk as well as be printed out. The current Hitachi inverter set up can be compared with the set up in a file - a particularly useful feature when trouble shooting or retrofitting Hitachi inverter drives.

The software is packaged together with getting started and technical manual and a cable that plugs into the serial port of the PC with a special adapter that fits the serial communications port on the Hitachi inverters. A special worldwide technical support service is available on the Internet at: www.drivemanager.com.
