The following inputs can be used for special functions:
● C230-2, C240: As inputs for measuring pulses for local measuring (M1, M2)
With a signal edge at the relevant input, the current actual values of one or more encoders
connected to X3 to X6 are measured with positioning accuracy to determine lengths or
distances.
The assignment of inputs is not fixed; the special use is activated in the SCOUT engineering
system during configuration of the Measuring Input TO via the measuring input number.
● C230-2, C240: As inputs for external zero mark signals (B1...B4)
With a signal edge at the relevant input, the current encoder value of the associated axis
is acquired with positioning accuracy in order to record the reference coordinates.
The assignment of the inputs to the encoders is fixed, and the special use is activated in
the SIMOTION SCOUT engineering system.
– B1 → axis 1 (encoder at X3)
– B2 → axis 2 (encoder at X4)
– B3 → axis 3 (Encoder at X5)
– B4 → axis 4 (encoder at X6)
● As inputs for measuring pulses for global measuring (B1 to B4) on the C240/C240 PN
Alternatively to the "external zero mark signals" function, these inputs can be used on the
C240 / C240 PN for global measuring.
Note: The inputs for global measurement (B1 to B4) can be used in addition to the inputs
for local measurement (M1, M2).
With a signal edge at the relevant input, the current actual values of one or more encoders
are measured with positioning accuracy in order to provide information for determining
lengths or distances (possible with any encoders included in the project).
The assignment of inputs is not fixed; the special use is activated in the SCOUT engineering
system during configuration of the Measuring Input TO (see the configuration example
below for global measuring).
Up to two edges can be measured for each position-control cycle clock of the Measuring
Input TO.
The measured values must be read from the user program before they can be overwritten
by a new measurement.
Global measuring can be used for the following applications:
– Several Measuring Input TOs on one axis/encoder where they can be active
simultaneously
– Several Measuring Input TOs are assigned to one measuring input (where one
Measuring Input TO is interconnected to one measuring input and the remaining
Measuring Input TOs are configured as listening measuring inputs)
This functionality enables one measuring input to act on several Measuring Input TOs
and thus on several axes / external encoders.
– In addition to single measuring, cyclic measuring is also supported
