Abstract
The utility model discloses an abnormal opening alarm circuit of a brake unit. The utility model can alarm in time when detecting the abnormal opening of the brake unit and take the stopping measures.
Description
Technical Field
The utility model relates to the technical field of electronics, in particular to an abnormal opening alarm circuit of a brake unit.
Background
As a core component of a numerical control machine, a servo motor controller directly influences the performance of a product. In order to ensure the production safety, an alarm device must be perfected so as to ensure the safety of operators and prolong the service life of equipment. At present, a servo motor controller focuses on conventional alarming mostly and ignores abnormal alarming of a brake unit.
Disclosure of Invention
The technical scheme adopted by the utility model is as follows:
alarm circuit is opened unusually to brake unit, including resistance R58, R57, R56, R55 and R44, electric capacity C50, C33, opto-coupler isolation PC8, opto-coupler isolation PC 8's right side parallel capacitance C50, electric capacity C50 right side parallel resistance R55, resistance R55 is in proper order series resistance R56, R57, R58, opto-coupler isolation PC 8's left side is the phototriode, the left phototriode collecting electrode of opto-coupler isolation PC8 is connected with resistance R44 one end and electric capacity C33 one end, the external power VCC is connected to the resistance R44 other end, electric capacity C33 other end ground connection.
Has the advantages that: the alarm device can give an alarm in time when the abnormal opening of the brake unit is detected, and a shutdown measure is taken.
Drawings
FIG. 1 is a block diagram of the present invention.
Detailed Description
BFO is a brake unit abnormal opening detection signal. The input signal P3 is a brake detection signal. The circuit consists of R58, R57, R56, R55, R44, capacitors C50 and C33 and an optical coupling isolation PC8 of a TLP621 type.
When the input signal P3 is at a low level, the optical coupling isolation PC8 is not conducted, and BFO outputs a high level, which represents that no abnormality exists in the current brake unit.
When an input signal P3 is at a high level, the optical coupling isolation PC8 is conducted, BFO outputs a low level, the current brake unit is abnormally opened, an upper layer servo motor controller is required to alarm and display, and the motor is stopped.
