1 to 4 with MOSAIC M1 fw <4.0 or MOSAIC M1S< 5.1 or MVx fw < 2.0. In the case of thresholds
greater than 1, the input pins for the selection of the specific threshold will appear in the lower part
of the function block. Let the user to choose which threshold has to be enabled.
Pitch: If the Axis Type chosen was linear and rotational, this field allows you to enter the sensor pitch
to obtain a conversion between sensor revolutions and distance travelled.
Proximity choice: It allows you to choose the type of proximity
sensor from PNP, NPN, Normally Open (NA) and Normally
Closed (NC), with 3 or 4 wires.
(In order to ensure a Performance Level = PLe use a proximity
switch type PNP NO: ref. “Interleaved proximity -> page 40).
Measurement: Enter in this field the number of pulses/revolution (in the case of rotational sensor)
or µm/pulse (linear sensor) relating to the sensor used
Verification: Enter in this field the number of pulses/revolution (in the case of rotational sensor) or
µm/pulse (linear sensor) relating to the second sensor used.
Gear Ratio: This parameter is active if there are two sensors on the selected axis. This parameter
allows you to enter the ratio between the two sensors. If both sensors are on the same moving parts,
the ratio will be 1 otherwise the number corresponding to the report must be entered. E.g. there are
an encoder and a proximity switch, and the latter is on a moving part that (due to a gear reduction
ratio) rotates at twice the speed of the encoder. Therefore, this value must be set at 2.
Hysteresis (%): It represents the percentage hysteresis (the percentage is calculated from the
threshold value) below which the speed change is filtered.
Speed 1…8: Enter in this field the maximum speed value above which the function block output
(OVER) will be 0 (FALSE). If the measured speed is less than the set value, the function block output
(OVER) will be 1 (TRUE). The speed value could be entered with the decimal point provided that
MOSAIC M1 fw >= 4.0 or MOSAIC M1S fw >= 5.1 or MOSAIC M1S COM and MVx fw >= 2.0 were used.
