Encoder failure diagnosis circuit of rotary motor system

摘要

In this case, the incoder controlling the motor and other rotating prime movers is used to determine whether the incoder is a bad circuit, and it is easy to judge whether it is bad.In this high-level case, the pulse (21) is generated by the mutual signal of input a and B,The download signal (U / D) of the above pulse generation means (21) and the logic curve cluster (37) of the ine,The pulse generating means (21) shows that the pulse signal (P) is the second logic multiplier group (38) of the signal and logic multiplication,The output signals of the first and second logic multiplier groups (37, 38) are the service / download counters (22) input by the up / download input group and the Clark port respectively,The output signal (23) of the above industry / download counter (22),It is composed of a control signal (35) outputting a control signal with the enterprise / download counter (22) and the laizhixiutuan (23).
