摘要：A synchronization control device and a synchronization control method areprovided in which it includes controllers Am and Asl of a master section and a slave

section for accurately synchronizing rotational frequency and rotation phases of drivingelectric motors Mm and Msl. The controller Asl includes rotational frequency detectorsSsl, Fsl, a master phase counter Cml, and a slave phase counter Csl, and detects at alltimes both of a rotational frequency and a rotation phase of the electric motors Mm ofthe master based upon an output of the rotary encoder Pm, and further detects at alltimes both of a rotational frequency and a rotation phase of the electric motor Msl ofthe slave. A phase deviation calculator Hsl is provided to calculate synchronization phasedeviation at all times, and when a switch RYsl is actuated, it corrects an output of therotational frequency detection means Ssl based upon the phase deviation and matchesorigins of the electric motors of the master section and the slave section to shift theoperation to synchronization control.
