In this mode, only the synchronous cam is repeated cyclically.
After the lead-in signal is set, the lead-in movement is performed once before switching to the synchronous cam.
When the mcTRANSITION_OFF mode is used, a LeadIn signal must also be set in order to start the movement.
If mcLEAD_IN is not enabled, the system switches directly from standstill to the sync cam.
After setting the lead-out signal, the lead-out movement is performed once after the sync cam and ends with the standstill of the slave axis.
If mcLEAD_OUT is not enabled, the system switches directly to standstill from the sync cam.
After the lead-in signal is set again, the sequence begins the next time the MasterStartPosition is reached.
Application example
Packaging products
Products moving on a belt should be placed in packages for further processing. The incoming and outgoing belts, as well as the axes with the packaging tools are all coupled to a master axis. The movements of the packaging tools are defined by cams. If there are no incoming products, the packaging tool should be halted in a waiting position. When more products arrive, it should leave the waiting position and enter the cam.
Information:
•The sum of "LeadInSlaveDistance" and "LeadOutSlaveDistance" should equal the "SlaveInterval"; otherwise, the waiting position of the slave is shifted.
•The parameter "MasterInterval" has no effect once the coupling has been enabled.
