The X200 manual I found on-line: http://www.hitachi-america.us/products/business/inverters/products/ac_variable_speed_drives/x200/ looks very similar to my SJ200-2 and has the same register addresses for at least the major functions. So when I get my SJ done you'll most likely have a Modbus component you can use. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
