Abstract:

Facing the problem that the control of the density motor used in current seamless underwear machines is unstable, this research was carried out to investigate the performance characteristics of the density motor, proposing a density motor control scheme based on CAN bus. According to the processing characteristics of the density motor control stitch cam, the overall implementation of the control technology was expounded. The key circuit design and program algorithm was studied, and the protocol for controlling the action characteristics of the density motor was established. In order to avoid the long-term operation of density motor appearing the horizontal stripes caused by the lost step phenomenon, detecting error mode by zero-return was proposed. The test results indicate that the control technology facilitate the position control of the density motor and improve the stability of the seamless underwear machine density motor control, with cost savings compared to density motors with encoders, meeting the control requirements of the seamless underwear machine for the density motor.
