(54) | Textile machine, standby position determining method of driven member of winding unit, and winding unit |
(57) A stepping motor moves an upper-yarn catching member (30) by an amount corresponding
to a specified number of pulses. A magnet sensor detects an origin position, which
is a reference position, of the upper-yarn catching member (30). A number-of-pulse
counting section obtains an actual measurement value, which is the number of pulses
necessary for moving the upper-yarn catching member (30) from a target position to
the origin position. A drive control section determines a standby position of the
upper-yarn catching member (30) in view of the actual measurement number counted by
the number-of-pulse counting section, a theoretical value, and the origin position.
