Burst Mode
Enables the system to be absolute even though
data transfer is through incremental method. In
the event of power failure, the controller can be
programmed to automatically send a signal to the
Zero Pulse
By sending a signal to the probe at any time in the
stroke, a new zero point can be established. When
using the burst input, the absolute position provided
will be relative to the established zero position.
In probes with volatile storage, the zero point will
The type of signal needed for the Burst / Zero inputs:
E = Sinking (PLC Sourcing Outputs)
C = Sourcing (PLC Sinking Outputs)
T = TTL

probe then the probe will respond with the current
position data. An input signal to the probe will cause
a burst of data, representing the absolute position,
to be fed back to the controller.
be kept until a new zero pulse is sent or until the
probe loses power. Probes with nonvolatile storage
will store the zero position even if you lose power.
The nonvolatile zero can be set 100,000 times; the
volatile zero can be set an infinite number of times.
