Servo Technology
The
heart of a multi-axis automation system is the ability to synchronize
the motion of multiple motors to a designated "master" source device.

Depending on the machine application, a source device may be an
encoder device measuring web travel, position feedback from another
motor that is driving a feed roll, or an Emerald Virtual (software)
Motor. A Virtual Motor provides a software-configured internal master
source with control over its virtual distance, speed and acceleration.
Synchronization between the source device and a servomotor is
achieved using the Emerald electronic gear ratio or electronic cam
motion functions. The process starts by locking the master source device
to
the slave servomotor. How the source device gets locked to the
servomotor is critical especially when the source is running. The
Emerald Automation Controller provides eight lock methods for smooth and
accurate transition regardless of the speed of the source. The source
device and the lock method are specified first. Then, the lock control
is enabled to start the synchronization process.
Digital outputs are synchronized to a master source using the
programmable limit switch (PLS) function. Up to eight independent PLS
engines can be enabled with each engine controlling the action of
sixteen outputs. Digital outputs can be located on the servo drive or on
the SERCOS network using 3rd party I/O interface blocks.
