Introduction | Speed or angular synchronism?
12.1.4 Speed or angular synchronism?
The decision whether to use a speed or angular synchronism mainly refers to the TA
"Electronic gearbox"
(C 297)
Angular synchronism
Use the angular synchronism if the material is not able to absorb any force and no
remaining positional variation may be available. Please note that a position controller
always causes additional trouble in a track since disturbances and reference value
variations must be compensated exactly.
Speed synchronism
Use the speed synchronism if the material is able to absorb force which ensures a better
concentricity.
12.1.5 Rail or cascade structure?
Rail structure
All drives obtain the same master value/master angle.
Cascade structure
Each drive obtains its own master value/master angle which is created or merely prepared
through the upstream drive.
12.1.6 Master or actual value transfer?
Master value transmission
The master value transfer results in a much quieter machine running. The mark
corrections, superimposed control functions and disturbances of the drive, however, do
not affect the system.
Actual value transfer
The actual value transfer results in an uneven machine running. Mark corrections,
superimposed control functions and disturbances of the leading drive affect the system.
Note!
