Control And Status Signals; Distance Measurement - Danfoss iC7 Motion Series Application Manual

Application Guide | iC7 Series Motion

Control and Status Signals

2.12.5.2
Controlling touch probes is done by the following control signals:
Control signal (input)
Touch Probe 1 Enable
Touch Probe 2 Enable
Touch Probe 1
Touch Probe 2
The following status signals are available for monitoring Touch Probe status:
Status signal (output)
Touch Probe 1 Detected
Touch Probe 2 Detected
Touch Probe 1 Active
Touch Probe 2 Active

Distance Measurement

2.12.5.3
The drive can measure the distance between 2 Touch Probe events in position units. It can be the distance between 2 separate Touch
Probes or the distance between 2 instances of the same Touch Probe. The measured distance is shown in parameter 5.18.3.1.1 Touch
Probe Distance, and the number of measurements is shown in parameter 5.18.3.1.3 Distance Measurement Counter. The counter is reset
when the source selection is changed.
Measurement is done between 2 sources, A and B, selected with parameters 5.18.3.2.1 Selection Source A and 5.18.3.2.2 Selection Source B
with the following selections:
None
l
Touch Probe 1
l
Touch Probe 2
l
The distance is measured between source B and the latest occurrence of source A and is calculated at every occurrence of source B:
Distance = [Position of source B] – [Position of source A].
The following illustrations show how the distance is measured in different scenarios:
