Abstract (en)

A drive control circuit (21), a driving circuit (22) and a pole position detector (22a) are combined together and connected to a knitting control unit (10). When a stop switch (SW2) is operated, for instance, the knitting control unit (10) causes the drive control circuit (21) and the driving circuit (22) to move a knitting head assembly (W) to its rearward movement limit and outputs a clear signal (S5). Upon receiving the clear signal (S5), the driving circuit (22) outputs a reset signal (S7) to the pole position detector (22a), so that relative position (y) of magnetic poles of a stator (M1) and the movable part (M2) detected by the pole position detector (22a) by using a sensor (A) is properly corrected. <IMAGE>
