Measurement system, control device, measurement method, and program

A measurement method for measuring an amount of position correction to be applied to a synchronous drive system including:

• a first main shaft and a second main shaft that are connected in parallel to each other via a sub shaft and include a first motor and a second motor, respectively;
• and a first controller and a second controller that respectively control the first motor and the second motor to cause the first main shaft and the second main shaft to move in an axial direction in synchronization with each other, the measurement method comprising:
• a command processing step for giving a same position command to the first controller and the second controller to cause the first controller and the second controller to control the first motor and the second motor to perform a test operation in which the first main shaft and the second main shaft move to designated positions in synchronization with each other;
• a first acquisition processing step for acquiring first information on a first force to be applied to the first main shaft and a second force to be applied to the second main shaft during the test operation;
• a second acquisition processing step for acquiring second information on positions of the first motor and the second motor during the test operation;
• and
• a calculation processing step for calculating the amount of position correction of at least one of the first motor and the second motor in order to correct a position shift between the first main shaft and the second main shaft based on the first information and the second information.
