Next, the driving machine life assessment device 100 involved by explanation embodiment 1 enters to the life-span of driving machine 200
The processing of control unit 105 when row is evaluated.The processing of control unit 105 is with the processing being controlled to motor 201 and to dynamic
Make the processing that quantity of state is calculated and exported to evaluation processing unit 106.
Fig. 3 is the flow chart for the processing for representing the control unit 105 involved by embodiment 1.Control unit 105 is from external device (ED)
300 acquirements action desired value (step S11).Control unit 105 obtains what is exported from driving machine 200 after acquirement action desired value
Value of feedback (step S12).Next, control unit 105 obtains the dynamic of driving machine 200 based on the value of feedback obtained from driving machine 200
Make quantity of state (step S13).Control unit 105 exports the operating state amount obtained in step s 13 to processing unit 106 is evaluated
(step S14).Value of feedback of the control unit 105 based on driving machine 200 and the action desired value being enter to, to flowing through motor
201 driving electricity consumption stream is calculated, and the driving calculated is exported with electric current to motor 201, makes the feedback of driving machine 200
Value follows the action desired value (step S15) being enter to.In addition, step S15 both can step S13 and step S14 it
It is preceding to carry out, it can also be carried out between step S13 and step S14.
Next, evaluation when explanation driving machine life assessment device 100 was evaluated the life-span of driving machine 200 is handled
The processing of the processing in portion 106, i.e. life-span formula operational part 107 and life-span formula evaluation section 108.Fig. 4 is represented involved by embodiment 1
Evaluation processing unit 106 processing flow chart, i.e. represent the processing of life-span formula operational part 107 and life-span formula evaluation section 108
Flow chart.Fig. 5 is the flow chart for representing the life assessment processing involved by embodiment 1, is the step in the flow chart by Fig. 4
The figure that one example of S23 specific processing is illustrated in detail in.When being evaluated in the life-span to driving machine 200, input unit 104
Received the processing of the input of the life-span formula used in the life assessment of driving machine 200.Input unit 104 will be by receiving the longevity
The input of life formula and the life-span formula that inputs into is exported to processing unit 106 is evaluated.It is example as life-span formula in embodiment 1
The situation of the positioning number of times comprising electromotor velocity and movable piece such as in calculating formula and illustrate.Following embodiment
It is same.Life-span formula operational part 107 obtain it is being received by input unit 104, in calculating formula comprising electromotor velocity and can
The life-span formula (step S21) of the positioning number of times of moving part.
Life-span formula operational part 107 obtains the operating state amount obtained in step s 13 by control unit 105 from control unit 105
(step S22).Life-span formula operational part 107 is secondary using the positioning of electromotor velocity and movable piece in acquired operating state amount
Number, performs input to the computing of the life-span formula of input unit 104, life-span formula evaluation section 108 is according to the computing of life-span formula operational part 107
As a result the life-span is evaluated (step S23).
Using Fig. 5, an example of step S23 specific processing is illustrated.Life-span formula operational part 107 is using being taken
The positioning number of times of electromotor velocity and movable piece in the operating state amount obtained, to inputting to the calculating formula progress of input unit 104
Calculate (step S31).Specifically, the positioning number of times of electromotor velocity and movable piece is substituting to calculating formula and calculated.
Then, life-span formula operational part 107 exports the result of calculation of calculating formula to life-span formula evaluation section 108.Life-span formula evaluation section 108 from
Life-span formula operational part 107 obtains the result of calculation of calculating formula, by the result of calculation of calculating formula and the life-span of input to input unit 104
Threshold value is compared, and obtains relation (step S32) between the two.108 pairs of life-span formula evaluation section obtain in step s 32 two
Whether the relation of person, which meets input to the equal sign or the sign of inequality of input unit 104, is judged (step S33).
Life-span formula evaluation section 108 is meeting input to the equal sign of input unit 104 by step S32 both relations obtained
Or be evaluated as driving machine 200 in the case of (step S33 is Yes), i.e. life-span formula establishment in the case of the sign of inequality and be not reaching to the longevity
Order (step S34), terminate flow.On the other hand, life-span formula evaluation section 108 is in both relations obtained by step S32
Be unsatisfactory for input to input unit 104 equal sign or the sign of inequality in the case of (step S33 be No), the i.e. invalid situation of life-span formula
Under, it is evaluated as driving machine 200 and reaches the life-span (step S35), terminates flow.In addition, in embodiment 1, life-span formula into
It is to be not reaching to the life-span (driving machine 200 is not above the life-span) in the case of vertical, is to reach in the case that formula is invalid in the life-span
Life-span (driving machine 200 exceedes the life-span), but also can be by the way that the sign of inequality of life-span formula is reversed, so that the feelings that life-span formula is set up
Processing in the case that condition and life-span formula are invalid is reversed.
Driving machine life assessment device 100 receives the input of life-span formula by input unit 104, uses driving machine 200
Thus operating state amount be to driving machine 200 to carrying out computing by the life-span formula that receives the input of life-span formula and input into
It is no to reach that the life-span is evaluated.Therefore, driving machine life assessment device 100 copes with drive environment and the drive of driving machine 200
The change of dynamic condition, can simply be evaluated the life-span of driving machine 200 under various drive environments and drive condition.
In addition, the tool of driving machine life assessment device 100 has the advantage that, i.e. the rolling that can be included for driving machine 200
Ballscrew or bearing etc. bear each part of load, for example, the expression prompted using the manufacturer by each part the specified longevity
The life-span formula of life carries out the evaluation in life-span.In addition, be not limited to this, can also be directed to each part, using with by manufacturer
The different life-span formula of the life-span formula that prompts.
In addition, the tool of driving machine life assessment device 100 has the advantage that, i.e. the driving ring of driving machine 200 need not be equipped with
Border and drive condition and the formula or algorithm that are used in the evaluation in the life-span of drive mechanism etc., therefore, it is possible to adjust to changed conditions
Ground is driven the evaluation in the life-span of machine 200.Structure disclosed in embodiment 1, can also be suitably applied to following reality
Apply mode.
