Abstract

The invention discloses an IPM module fault detection and protection circuit for a servo driver. The circuit comprises an IPM module basic peripheral circuit which carries out the fault triggering, temperature sampling, current sampling and fault output processing of an IPM module; an over-current protection circuit is used for carrying out over-current protection on the IPM module; a temperatureprotection circuit is used for carrying out over-temperature protection on the IPM module; a voltage detection and protection circuit is used for detecting the working voltage of the IPM module and carrying out overvoltage protection on the IPM module; a fault feedback circuit is used for feeding back the fault of the IPM module; an IPM module fault detection and protection circuit is comprehensive in fault protection type, concise in protection logic and unified in protection circuit topology; the whole circuit is low in cost and high in reliability, and meets the use requirements.

Description

technical field [0001] The invention relates to the field of industrial automation / robot circuit design, in particular to an IPM module fault detection and protection circuit of a servo driver. Background technique [0002] As the drive control unit in the field of industrial automation and robotics, the servo drive is the basis of the entire motion control system. The Intelligent Power Integrated Module (IPM for short), as the core component of energy conversion in the low-power servo driver, drives the servo motor to complete all the motion commands of the upper controller, and accurately realizes the motion control of the control object. In the process of power change, the IPM module needs to implement high switching frequency, and needs to withstand high du / dt (voltage change rate), high di / dt (current change rate), such as control program error, sudden change of control object, environmental interference and other factors , will make the IPM may withstand the relevant ...
