SIMOVERT MASTERDRIVES Compendium Motion Control 9-81
The following rules must be followed during configuration:
♦ One of the axes is defined as the master drive.
♦ The master drive must also be the SIMOLINK master (dispatcher).
The module address is zero.
♦ The virtual master axis is enabled [832] on the master drive.
♦ All drives, including the master drive, move in synchronism with the
virtual master axis [832].
♦ The output of the virtual master axis is wired to the SIMOLINK send
block [160].
♦ The input of the synchronization block is connected to the receive
block of the SIMOLINK,
including for the master drive.
The graphic below illustrates the path of the master value of the virtual
master axis, and the controller structure.
