It is commonly encountered double-core axle 34, pallet 35 reports drive failures, failure F015.But listed by the service manual provided as Siemens Company
Failure cause and solution out is not comprehensive enough, causes user to find failure cause and needs to expend great effort.Sometimes
There is F015 failure in AC frequency control apparatus 211,221, and all solutions provided on service manual all can not gram
The problem of taking F015 failure, a simple and common way is to be resetted at this time.However, one can be run after sometimes resetting
The section time, but tripping sometimes reset to be repeated as many times could reluctantly it is normal for a moment.Equipment can be damaged by repeatedly resetting.In order to
Better solution is provided, the inventor of the utility model has carried out a large amount of test and analysis.Firstly, inventor by
AC frequency control apparatus and field device are observed under equipment failure state, find the operation of motor when reporting failure
Electric current (R004) may rapidly rise, and sometimes up to more than 100 amperes (rated current of motor 58.5A), but field device is transported
Scanning frequency degree is relatively slow, and running current is more than report failure F015 tripping after AC frequency control apparatus protective current.Check scene
Motor body is without exception, and motor cable is mechanical without stall without over the ground and short circuit, motor internal contracting brake open it is normal, between brake block adjustment
Gap is 60dmm or so, and brake block is without abrasion.Then, AC frequency control apparatus parameter is modified as P100=3 from P100=4,
P130=11 is modified as P130=10, and using frequency control system rotating machinery, AC frequency control apparatus can be operated normally,
Current of electric is in 30A or so.But it is unable to run again after restoring parameter.Based on this, inventor's analysis may be velocity feedback
It goes wrong.Then, inventor slowly runs equipment under frequency control system, with oscillograph test pulse encoder A+, A-,
, there is the waveform of very irregular in the feedback signal waveform of B+, B-, C+, C- triple channel and normal pulse coder is regular
Square wave.Then, inventor analyzes, it may be possible to which AC frequency control apparatus is in actual moving process, and feedback speed signal is not just
It often or loses, causes AC frequency control apparatus report overload or overcurrent fault.Velocity feedback is using photoelectricity incremental
, there is two o'clock in the reason of encoder, encoder leads to this failure of transmission device report: 1, when encoder feedback signal abnormal, motor
Setting speed is not achieved in main given speed, just raising speed always, and operating current is caused to increase.2, when encoder pulse dropout,
There is large error in the speed ring of AC frequency control apparatus, has exceeded overload or overcurrent after controllable adjustment range, exchange
Frequency converter is possible to quote F015 failure.Inventor thinks that failure is that encoder related system original part causes as a result,
Fault trip.Later, inventor checks that encoder power supply (DC24V), wiring, connecting rod, installation accuracy are normal, more
Test waveform is still such after changing encoder.Based on above-mentioned analysis, inventor draws a conclusion, and is causing encoder feedback signal not just
It often may be that encoder route is interfered or route is too long that signal is caused to be decayed.

The interference arrived increases the reliability of system, reduces the probability of system failure.Importantly, may be implemented to reduce
Siemens 6SE70 series AC frequency control apparatus reports the frequency of F015 failure.It may be noted that due to Siemens 6SE70 series
It is not interfered comprising code device signal line among failure cause listed by the service manual of AC frequency control apparatus, so
When equipment reports F015 failure because of signal interference, if compareing the solution of service manual first according to common maintenance mode
Certainly measure is successively checked, all invalid to determine failure cause by the way that each component is tested and analyzed again later,
This needs takes considerable time.Therefore the interference being subject to by reduction encoder route is so that the exchange of Siemens's 6SE70 series becomes
Frequency modulation speed variator reports the frequency of F015 failure to reduce, so that saving a large amount of repair times is unexpected effect.Due to F015
