Abstract

PURPOSE:To control a process, by converting the process variable signal to a digital quantity by sampling and subjecting this digital signal to the operation processing and giving the operation result to an operation device. CONSTITUTION:In a position controller, when its own output of PID operation is connected to an input terminal P1, a preceding output value out of operation is taken in, and thus, this connection is equivalent to an internal connection, and a speed operation output DELTACN is integrated practically in the operation output obtained in an output terminal OUT, thus obtaining a position output. In a speed controller, when terminals are so connected that 0% fixed value data FIX is given to the input terminal P1 and a turn-on enable signal INL is given to an input terminal P2, the speed operation output DELTACN is outputted as it is as the operation output obtained in the output terminal OUT, thus constituting a speed output PID controller.
