PROBLEM TO BE SOLVED: To obtain a motor synchronization control device which can maintain synchronization of each shaft with high accuracy, even if limits are imposed to a control input of each shaft. SOLUTION: The motor synchronization control device is such that the control device includes a formation amount synchronizing section 4a which uses, as an input, a position correction amount for correcting a position difference of own shaft motor which is the difference between a position command, which is generated by each of two or more motor drive control devices individually driving the two or more shafts and is common to each shaft, and a position detection value detected by own shaft motor, and selects a position correction amount which is the latest in responsiveness from between two or more position correction amounts as a synchronization post-position correction amount; and each of the two or more motor drive control devices calculates a control input to own shaft motor, by using a corrected position difference which is obtained by subtracting the synchronization post-position correction amount from the position difference of own shaft.
