Cam profile data creation apparatus and synchronization controller

A control system for controlling an electronic cam, the control system comprising:

• a processor configured to:
• set cam profile data in which a phase of a drive shaft of the electronic cam is associated with a set displacement as displacement of a driven shaft of the electronic cam;
• set a rotation speed of the drive shaft;
• set an allowable error for a displacement of the driven shaft;
• find a predictive displacement as displacement of the driven shaft when the drive shaft rotates at the rotation speed based on the cam profile data;
• a display configured to display the set displacement and the predictive displacement in a manner such that they can be compared with each other and changes a form of the display depending on whether an error between the set displacement and the predictive displacement falls within the range of the allowable error;
• and
• a controller configured to receive the rotation speed from the processor and control the electronic cam by controlling the drive shaft to rotate at the rotation speed when the comparison indicates that error falls within the range of the allowable error.
