Encoder correction system

According to the encoder correction system provided by the embodiment of the utility model, the characteristic that the motion parameters detected by the photoelectric encoder are not related to the assembly position of the photoelectric encoder on the motor equipment and do not need to be corrected is utilized, and the motion parameters are directly fed back to the driver on the motor equipment where the target encoder is located through the photoelectric encoder; and therefore, the transmission rotating shaft of the motor equipment can achieve a stable operation state without being driven byan external motor, the problem that the correction result is influenced by factors such as friction, loosening, slipping and the like of the coupler is avoided, and the correction precision of the encoder is improved. Moreover, because the transmission rotating shaft of the motor equipment where the target encoder is located achieves stable operation and is expanded and does not need to be drivenby an external motor, the
