STAND STILL
The function block STAND STILL monitors the speed of a
device, generating the Zero to 1 (TRUE) output when the
speed is lower than a selected value.
Parameters
Axis Type:
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.
Sensor Type:
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.
Measuring device:
It defines the type of sensor(s) used. The possible choices
are:
• Encoder
• Proximity
• E Proximity
• Prox Proximity2
• En Encoder2
Pitch:
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.
Proximity choice:
It allows you to choose the type of proximity sensor from PNP, NPN, Normally Open (NO) and Normally Closed
(NC), with 3 or 4 wires.
(In order to ensure a Performance Level = PLe use a proximity switch type PNP, NO)
Proximity Interleaved:
When an axis of the UG 6917 module is configured for a
measurement with two proximity switches, these can be
configured in interleaved mode. Under the conditions listed
below the system reaches a Performance Level = PLe
• Proximity switches must be fitted such that the
recorded signals overlap.
• Proximity switches must be fitted such that at least
one is always activated.
Measurement:
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.
