Abstract

PURPOSE:To perform accurate length detection by fitting a resolver to a rotary body and inputting a start signal and a stop signal for length detection. CONSTITUTION:The rotating speed of the rotary body 1 is detected by the resolver 8 fitted to the rotary body 1 and sent to a microprocessor 11 through a revolver/digital converter 9. The microprocessor 11 stores a memory 12 with the position of the resolver at the point of time when the length detection start signal is inputted through an external interface 10, and compares the position of the resolver at the point of time of the input of the length detection end signal with the last stored position of the resolver to detect the length, which is stored in the memory 12. The microprocessor 11 sends a completion signal to a programmable controller 5 through an interface 13 and reads the contents of the memory1 2 through the interface 13 with this completion signal to detect the length.
