Sewing machine

A non-transitory computer-readable medium containing a computer program executable on a control unit of a sewing machine, the sewing machine comprising:

• a movement detection unit for sensing a movement of a material to be sewn to detect a movement amount of the material;
• a drive motor for operating a needle;
• and a storage unit for storing a sewing speed and a sewing pitch, wherein the control unit is configured to operate the drive motor,
• wherein when executed by the control unit, the computer program causes the control unit to implement a first control mode or a second control mode,
• wherein in the first control mode, when a detected value by the movement detection unit indicates a start of the movement of the material, the control unit keeps a stopped state of the drive motor until the detected value by the movement detection unit reaches a predetermined first threshold, and then operates the drive motor at the stored sewing speed when a detected value by the movement detection unit exceeds the first threshold,
• wherein in the second control mode, when a detected value by the movement detection unit indicates a start of the movement of the material, the control unit keeps a stopped state of the drive motor until the detected value by the movement detection unit reaches a predetermined second threshold, and then operates the drive motor such that sewing is carried out at the stored sewing pitch on the basis of a detected value by the movement detection unit when the detected value by the movement detection unit exceeds the second threshold, and
• wherein the first control mode and the second control mode for the control unit are switchable.
