Fork Accelerating running between the upset displacement of 0-A °, travels at the uniform speed between the upset displacement of A °-B °,
Run slowly between the upset displacement of B °-C °, stop the operation of upset when being turned to described C °
Including:
Described controller utilize the number of the described count pulse that described high-speed counter added up by comparator with
Three described preset values compare；According to different comparative results, described reducing motor is with different fortune
Line frequency is run；
Wherein, when the number of described count pulse is more than 0, during less than described first threshold, described control
Device controls described converter and runs between 0 to first frequency, and described reducing motor is with 0 to first frequency
Between running frequency Accelerating running；
When the number of described count pulse is more than or equal to described first threshold, during less than described Second Threshold,
Described controller controls described converter and runs with described first frequency, and described reducing motor is with described first
The running frequency of frequency travels at the uniform speed；
When the number of described count pulse is more than or equal to described Second Threshold, during less than described three threshold value,
Described controller control described converter run between described first frequency is to 0, described reducing motor with
Described first frequency runs slowly to the running frequency between 0；
When the number of described count pulse is equal to described three threshold value, described controller controls described frequency conversion
Device is out of service, and described reducing motor is out of service.
9. panel turnover mechanism control system as claimed in claim 1, it is characterised in that described system is also wrapped
Include electromagnetic brake, for comprising signal out of service in the upset control signal that described controller sends
Time, brake the operating of described panel turnover mechanism.
