A “continuous latch mode” is supported by Sigma-5 servo amplifiers. In
this mode, the servo amplifier will automatically re-arm the latch function
to capture latches that may occur very close together, thus saving the
round trip time required to retrieve the latch status and re-arm the latch
from the controller. The controller will automatically store the latches into
a buffer in the
CONTINUOUS_REF data structure connected to the function
block. Up to 8 latch events can be defined as a single pattern. The mode
can be configured to operate once until a specific pattern has been
captured, or infinitely.
