Abstract
PURPOSE:To decrease the number of analog input setting points by setting each control mode via a common volume. CONSTITUTION:The set analog signal f a volume 4 of a control panel 3 is taken into a program controller 1 via a process input/output interface part 8. A central arithmetic unit 5 fetches said analog signal after A/D conversion. Then the unit 5 reads the reference value for rate conversion corresponding to a control mode out of a program memory part 6. The A/D converted value undergoes the rate conversion via said reference value. Based on this rate conversion, the control data is calculated to a dynamo drive system 2. The control data obtained through the arithmetic process is sent to the system 2 from the unit 5 via the part 8 as the control signal.
