Embodiment 1

[0055] The specific steps of system initialization zero point adjustment are as follows:

[0056] 1. After the system is powered on and turned on to set the zero point (or re-set the zero point by reset), observe the code value from the edge 1 (the difference between the zero point and the edge 1) and the 2 code value from the edge (the difference between the zero point and the edge) displayed on the screen. 2 encoding difference), (the closer the encoding values ​​from edge 1 and edge 2 are to the same, see Figure 4 , which means that the closer the zero position is to the center of the grating gap), adjust according to the adjustment direction prompted in the status bar.

[0057] 2. If the zero point cannot be found, the motor will continue to rotate and cannot stop, then turn off the power, first loosen the screw on the coupling close to the motor, and then in any direction (the angle of view when adjusting the coupling is from the encoder to the filter) Look in the direc...

Abstract

The invention relates to the field of positioning of transmission and control systems, in particular to a tunable filter transmission and control system and a zero point adjustment method of the tunable filter transmission and control system. After the system is powered on, a controller executes an initialization process. The initialization process mainly includes the step that whether the zero point position is detected or not and whether the zero point position is positioned or not are judged. The initialized zero regulation process is conducted through outage, coupling angular position regulation, power-on again and other steps. By means of the steps, the whole system can be made to be in an initialized state, namely the zero point position. If the operation that a zero point is regulated to the center of a grating photic zone does not exists, it means that the zero point position is not controlled, the zero point location position is random, and the fault that the zero point is missing occurs easily, and it is guaranteed that the initial zero point is stable and reliable in position by controlling the zero point location position.

Description

technical field [0001] The invention relates to the field of positioning of transmission and control systems, in particular to an adjustable filter transmission and control system and a zero point adjustment method thereof. Background technique [0002] When the transmission system does not adopt the transmission mode of harmonic drive reducer (transmission mode 1), the adjustment accuracy of the main shaft of the system depends entirely on the resolution of the photoelectric encoder, and a stepping motor with a large driving capacity is required to realize the adjustable Fast and high-precision tuning and positioning of the filter, see the block diagram figure 1 . [0003] When the transmission system adopts the transmission mode of harmonic transmission reducer (transmission mode 2), the adjustment accuracy of the system is related to the resolution of the photoelectric encoder and the product of the harmonic reduction ratio, so the adjustment accuracy of the entire trans...
