Document Type and Number:
Japanese Patent JPH07502939
Kind Code:
A
Abstract:
A control for an injection molding machine is provided including: a processor module producing set point signals in response to detection of coincidence of, selectably, analogue input signals, binary status signals, and elapsed time signals; and, a signal processing module for periodically producing control signals in response to the set point signals, measured parameter signals and control algorithms relating set point values and measured parameter values. A DC output interface module is provided including a plurality of DC output interface circuits for applying binary control signals to machine devices. The DC output interface circuits include self-latching over-current protection including means for sensing a latched condition thereof to produce an over-current fault indicating signal available to the processor module. The processor module includes an expansion bus for connection of the signal processing module and the DC output interface module.
