Description

technical field [0001] The invention relates to the technical field of motor debugging, in particular to an encoder reset device and an encoder reset method. Background technique [0002] After the installation and maintenance of the permanent magnet synchronous motor, the internal encoder needs to be cleared and calibrated, so that the driver of the synchronous motor can control the output rated power of the synchronous motor, so that the synchronous motor can output the required torque and speed , making the control of the driver more precise. [0003] The driver of the traditional permanent magnet synchronous motor does not have the function of clearing the encoder, and it is necessary to purchase an encoding device for the encoder separately. This kind of equipment is expensive, has complex functions, and cumbersome configuration, which is not conducive to the rapid production and installation of permanent magnet synchronous motors. maintain.
