Abstract
The invention discloses a kind of method that motion determines extreme position point, comprise step 1: motion moves in one direction and detects the size of power output；Step 2: then judge that when power is higher than preset value motion arrives the extreme position of the direction；Step 3: motion moves towards the direction contrary with step 1 and detects the size of power output；Step 4: then judge that when power is higher than preset value motion arrives the extreme position of the direction.When motion moves to the extreme position in a direction, due to the effect of positive stop, the power output of motion can become big, whether exceedes preset value by the size of detection power output and can be determined that whether motion reaches the extreme position of this direction of motion.If the size of power output exceedes preset value, then motion arrives extreme position；If the size of power output is not above preset value, then motion does not arrives extreme position.
Description
Technical field
The present invention relates to a kind of method determining extreme position point, a kind of motion determines extreme position point
Method.
Background technology
Motion less than a boundary determined, typically can install travel switch in order to ensure its range of movement additional, when
When motion moves to travel switch, travel switch sends signal, and the control system of motion is according to the letter of travel switch
Number determine motion according to certain algorithm stop motion.
This method of travel switch that installs additional, to determine position, is less reliable, when the dust in photoelectric travel limit switch
Time more, the signal of mistake can be produced, make motion produce the most serious accident.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that motion determines extreme position point, this fitness machine
Structure determines that the method for extreme position point can determine if to arrive with motion in the case of not installing travel switch additional
Extreme position, thus reduce cost, improve reliability.
In order to realize foregoing invention purpose, motion of the present invention determines the method for extreme position point, comprises step 1: fortune
Motivation structure moves in one direction and detects the size of power output；Step 2: then judge that motion arrives when power is higher than preset value
Reach the extreme position of the direction；Step 3: motion moves towards the direction contrary with step 1 and detects the size of power output；Step
Rapid 4: then judge that when power is higher than preset value motion arrives the extreme position of the direction.
When motion moves to the extreme position in a direction, due to the effect of positive stop, motion defeated
Exert oneself and can become big, whether exceed preset value by the size of detection power output and can be determined that whether motion reaches this motion
The extreme position in direction.If the size of power output exceedes preset value, then motion arrives extreme position；If power output
Size is not above preset value, then motion does not arrives extreme position.
Detailed description of the invention
Motion of the present invention determines the method for extreme position point, comprises step 1: motion moves also in one direction
The size of detection power output；Step 2: then judge that when power is higher than preset value motion arrives the extreme position of the direction；Step
Rapid 3: motion moves towards the direction contrary with step 1 and detects the size of power output；Step 4: when power is higher than preset value
Then judge that motion arrives the extreme position of the direction.
When motion moves to the extreme position in a direction, due to the effect of positive stop, motion defeated
Exert oneself and can become big, whether exceed preset value by the size of detection power output and can be determined that whether motion reaches this motion
The extreme position in direction.If the size of power output exceedes preset value, then motion arrives extreme position；If power output
Size is not above preset value, then motion does not arrives extreme position.
When making prime mover due to motor, the size of power output can be determined by the electric current of input motor, thus described
Detection power output be detection input motor electric current.
Claims (2)
1. the method that motion determines extreme position point, it is characterised in that: comprise step 1: motion is transported in one direction
Move and detect the size of power output；Step 2: then judge that when power is higher than preset value motion arrives the extreme position of the direction
Put；Step 3: motion moves towards the direction contrary with step 1 and detects the size of power output；Step 4: when power is higher than presetting
Then judge during value that motion arrives the extreme position of the direction.
Motion the most according to claim 1 determines the method for extreme position point, it is characterised in that: described detection is defeated
Exert oneself be detection input motor electric current.
