3.5 Sample Program 4: Phase Control with an Electronic Cam
3.5.1 Program Outline
The same operation for the mechanical cam synchronized to the roller connected to the line shaft will be per-
formed using a Servomotor. Phase synchronization, however, has not been used.
• The H06.02 drawing (ladder program) controls the operation.
• The two axes rotate synchronously according to the entered speed settings.
• The following configuration is used in this example.
Axis 1: Roller axis = Master axis
Axis 2: Cam axis = Slave axis. Performs cosine cam pattern operation in reference to the master axis.
• Cam pattern data is generated by the L06 drawing (ladder program).
Refer to
3.5.3 Program Details
for details on the sample program.
• This program is solely for the purpose of describing the MP2100 system startup. Care must be taken because
actual applications will differ.
• This system for the program has no power OFF circuit for the SERVOPACK in the event of emergency stops
or overtravel. Include a proper emergency stop circuit in actual applications.
