Control arrangement comprising synchroneous signal for knitting machine guide bars

A warp knitting machine comprising:

• at least one guide bar, said guide bar being axially reciprocatable;
• an electric setting motor coupled to said guide bar for reciprocating it;
• a position signal transmitter coupled to said guide bar for providing bar position signals signifying varying positions of said guide bar, said position signal transmitter being an absolute transmitter for uniquely assigning said bar position signals based on different positions of said guide bar;
• a main means having a main shaft and an electrical main motor for continually rotating said main shaft;
• a synchronizing signal transmitter coupled to said main means for providing synchronizing signals signifying varying angular positions of said main shaft, said synchronizing signal transmitter being an absolute rotational angle transmitter for uniquely assigning said synchronizing signals based on different angular positions of said main shaft;
• a schedule transmitter coupled to said synchronizing signal transmitter for generating in response to said synchronizing signals, position target values following at least one predetermined displacement schedule defined by a continual displacement function, said schedule transmitter being operable to definitively and singularly assign said position target values from each of the synchronizing signals in accordance with said continual displacement function;
• and
• a position control means coupled to said setting motor and said schedule transmitter and being responsive to said position target values for controlling said setting motor.
