In CNC machine tools or other numerical control equipment, position sensing components such as grating scales or encoders are often used, and the actual movement position and speed information of mechanical moving parts are measured. Then the value measured by the scale or the encoder requires a special receiving part to process. The signal output by a general encoder is an AB (or ABZ) phase orthogonal coded signal. The reason for this coding is to add direction information to the code stream, and it is also advantageous for anti-interference processing. Therefore, when receiving this signal, a special decoding interface circuit is needed, and the obtained data, that is, the actual motion position/position information, is transmitted to the processing unit, or transmitted to the central control system of the numerical control device through a bus (such as PCI), so that the control The software and hardware of the system compares the actual information with the ideal (logical) information, and then adjusts the position and speed of the moving parts according to the error results of the comparison, or performs other interrupted, switchable output actions to control the mechanical motion. the goal of. Even, through a complete algorithm to put position, speed, torque and other information into the system, do real-time feedback processing, which is what we call closed-loop (semi-closed loop) processing, our common algorithm is PID (or PI )algorithm. In this way, it is more convenient to let the mechanical equipment achieve fast, accurate and soft characteristics under fully automatic operation.

KNLE1-63 Residual Current Circuit Breaker With Over Load Protection
KNLE1-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
