39 Applications Alarm function Customizable alerts and resets for all possible operation errors allows production management to determine which alerts should be logged, automatically reset, halt production, result in a rejected part, etc. The log of machine alert data with time of each alert can also be printed. Quality management Logging of up to 7 aspects of cycle data for up to 10,000 cycles to USB or internal memory for quality management systems. Production management The user can configure the machine to stop after a defined number of cycles or a set time. The user can also configure, log, and monitor cycle data based on the user s choice of many criteria: cushion position, temperatures of heater zones, fill time, etc. Controller [IMC 700] Graph display Management of Process Parameter Up to 1,000 sets of process parameters (mold data with injection unit data) can be stored in internal memory and backed-up or retrieved from USB external memory. Easy retrieval of mold data from internal memory simplifies process changeovers. Core setting The user can monitor process performance graphically while logging injection speed and pressure, detailed information about charging status as well. Various kinds of core options can be applied by setting user-oriented programming for core operation. Courtesy As a result, the types of molds that can be produced have diversified. 39
