The function block monitors the speed
of a device, generating the Zero to 1 (TRUE) output when the
speed is within a prefixed range.
Parameters
It defines the type of axis controlled by the device. It
will be Linear in the case of a translation and will be Rotary in
the case of motion around an axis.
In the event that the previous parameter is
Linear, the Sensor Type defines the type of sensor connected to
the module inputs. It can be Rotary (e.g. shaft encoder) or
Linear (e.g. optical array). This choice allows to define the
following parameters.
It defines the type of sensor(s) used. The
possible choices are:
- Encoder
- Proximity
- Encoder+Proximity
- Proximity1+ Proximity2
- Encoder1+ Encoder2
If the Axis Type chosen was linear, this field allows you
to enter the sensor pitch to obtain a conversion between sensor
revolutions and distance travelled.
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 26).
Enter in this field the number of
pulses/revolution (in the case of rotary sensor) or µm/pulse
(linear sensor) relating to the sensor used.
Enter in this field the number of pulses/revolution
(in the case of rotary sensor) or µm/pulse (linear sensor)
relating to the second sensor used.
